9/9/2019 Mac Install Valgrind For Qt Creator
The run settings to specify depend on the type of the project and on the that you build and run the project with. Qt Creator automatically creates run configurations for your project. To view and modify them, select Projects Build & Run Run. The available run configurations are listed in the Run configuration field. To add run configurations for a project, select Add. To remove the current run configuration, select Remove.
Sudo apt-get install valgrind About 50 MB later, you will have valgrind installed Install the (Nokia) Qt SDK or Qt Creator. If you do not already have it, you can install the Nokia Qt SDK, but the procedure below will work with any install of Qt Creator. The approach outlined in this article can be used for desktop, Maemo and Simulator targets. Aug 30, 2012 - Qt is a cross-platform application framework written in C++. Examples: • Qt Creator (Windows, Linux & Mac). Sudo apt-get install valgrind.
To rename the current run configuration, select Rename. To prevent Qt Creator from automatically creating run configurations, select Tools Options Build & Run, and then deselect the Create suitable run configurations automatically check box. The run configurations for qmake projects derive their executable from the parsed.pro files. For more information on how the commands are constructed, see.
Qt Creator automatically adds run configurations for all targets specified in the CMake project file, CMakeLists.txt. Creating Run Configurations for Subprojects To prevent Qt Creator from automatically creating run configurations for SUBDIRS projects, specify the following variable in the.pro file of the SUBDIRS project: CONFIG += qtcrunnable. Qt Creator creates run configurations only for subprojects that also have CONFIG += qtcrunnable set in their.pro files. Specifying Run Settings for Desktop Device Types You can specify command line arguments to be passed to the executable and the working directory to use.
The working directory defaults to the directory of the build result. For console applications, check the Run in terminal check box. To specify the terminal to use on Linux and macOS, select Tools Options Environment System. To run with special environment variables set up, select them in the Run Environment section.
For more information, see. When building an application, Qt Creator creates a list of directories where the linker will look for libraries that the application links to. By default, the linked libraries are made visible to the executable that Qt Creator is attempting to run. Usually, you should disable this option only if it causes unwanted side-effects or if you use deployment steps, such as make install, and want to make sure that the deployed application will find the libraries also when it is run without Qt Creator. To disable library linking for the current project, deselect the Add build library search path to PATH check box.
To disable library linking for all projects, select Tools Options General, and then deselect the Add linker library search paths to run environment check box. The Use debug version of frameworks (DYLDIMAGESUFFIX=debug) option (only available on macOS) enables you to debug (for example, step into) linked frameworks, such as the Qt framework itself. You do not need this option for debugging your application code. You can also create custom executable run configurations where you can set the executable to be run. For more information, see. Specifying Valgrind Settings Qt Creator integrates for detecting memory leaks and profiling function execution.
You can configure the tools according to your needs. You can specify Valgrind settings either globally for all projects or separately for each project. To specify Valgrind settings for the current project:. In the Valgrind Settings section, select Custom. Specify Valgrind settings for the project.
For more information about the settings, see:. Click Restore Global to revert to the global settings.
To specify global Valgrind settings, select Tools Options Analyzer. Specifying Debugger Settings To select the languages to debug, select the Enable C and Enable QML check boxes. Note: Opening a socket at a well-known port presents a security risk. Anyone on the Internet could connect to the application that you are debugging and execute any JavaScript functions. Therefore, you must make sure that the port is properly protected by a firewall.
For more information about debugging, see. Specifying Run Settings for Android Devices To run and debug an application on an Android device, you must create connections from the development host to the device, as instructed in. A default set of Android Activity manager (am) start options is applied when starting applications. You can specify additional start options in the Activity manager start options field.
However, if the default options conflict with the added options, the application might not start. For example, to run the application as a particular user, enter the start option -user 10, where 10 is the user ID of the user account. You can specify shell commands to run before the application is started and after it is quit. For example, enter the following commands to unlock the screen and to switch to the user account 10 on the device before running the application. Am switch -user 0 input keyevent 82 Specifying Run Settings for Linux-Based Devices To run and debug an application on a Linux-based device, you must create connections from the development host to the device and add the device configurations to.
Click Manage Kits to add devices to kits. For more information, see. When you run the application, Qt Creator copies the files to the connected device. The run settings display the path to the executable file on the development host and on the device. To specify that another application launches your application, for example, enter the command in the Alternate executable on device field and select the Use this command instead check box.
You can specify command line arguments to pass to your application in the Arguments field. Specifying Run Settings for QNX Devices To run and debug an application on a QNX device, you must create connections from the development PC to the device.
Click Manage device configurations to create a connection. For more information, see. Specifying run settings for QNX Neutrino devices is very similar to. Specifying Run Settings for Embedded Devices To run and debug an application on an embedded device (commercial only), you must create connections from the development host to the device and add the device configurations to.
Select Manage Kits to add devices to kits. For more information, see the in the documentation. The run settings display the path to the executable file on the development host and on the device. For more information on the deployment steps, see.
Selecting the Run Environment Qt Creator automatically selects the environment used for running the application based on the type. You can edit the environment or select another environment in the Run Environment section. You can edit existing environment variables or add, reset and unset new variables.
When running on the desktop, the Build Environment is used by default, but you can also use the System Environment without the additions made to the build environment. For more information, see.
To run in a clean system environment, select Clean Environment. When running on a mobile device connected to the development host, Qt Creator fetches information about the Device Environment from the device. Usually, it does not make sense to edit the device environment.
To modify the environment variable values for the run environment, select Batch Edit. For more information, see. Specifying a Custom Executable to Run If you use CMake or the generic project type in Qt Creator, or want to run a custom desktop executable, create a Custom Executable run configuration for your project. For example, when working on a library, you can run a test application that links against the library. Specify the executable to run, command line arguments, working directory, and environment variables to use. Specifying Run Settings for Qt Quick UI Projects You can specify run settings for with Desktop device type:. In the Arguments field, you can specify command line arguments to be passed to the executable.

While it is not the only option, Qt Creator is the integrated development environment (IDE) of choice for Qt. It provides good support for developing for embedded systems, including cross-compiling, deploying to a target system, debugging and profiling.
It's free, well documented (1), and actively developed. Configuring Qt Creator for embedded development is sometimes a stumbling block for our Qt training students and consulting customers. In our recent Qt For Beginners webinar series (2) it was suggested we present detailed instructions showing how to configure Qt Creator for a common embedded board. That was an excellent suggestion, so here they are.
For this example, I'll use the Raspberry Pi platform. It is a popular and low-cost board that can be used for embedded applications. The steps would be similar for other boards, such as a BeagleBone Black. I'll outline the procedure to get an embedded development environment up and running, including the commands used and configuration screen shots. For this exercise I'm using a Raspberry Pi 3 running the Raspbian Linux distribution. Development will be on an Ubuntu Linux desktop using Qt 5.7.0 and Qt Creator 4.0.3. Here are the key steps:.
Install Qt Creator. Get a Linux image running on the target system. Set up the toolchain/SDK. Build a cross-compiled Qt.
Configure Qt Creator. Test the configuration and begin embedded development Let's get started. Install Qt Creator To begin, you need to have the Qt Creator IDE up and running on your desktop development system. The latest version at the time of writing is 4.0.3, with a 4.1.0 version in beta. A number of useful features were added in the version 4 series, so I highly recommend you use at least version 4.0.0. You can download precompiled versions of Qt Creator from.
You can choose to either install Qt Creator on its own or use the online installer, which will allow you to install Qt and Qt Creator based on your selection of components. There is also an offline Qt installer that includes all of the components and doesn't require any additional downloads. Of course, you can also build Qt Creator from source code. Make sure your Qt Creator installation works for native development using a native Qt version running on your desktop, as this is a prerequisite to extending it to work for embedded development.
I won't go over configuring Qt Creator for native desktop development as it is covered in the documentation, and in many cases it will automatically detect your installed Qt version and compiler and be ready to go the first time you fire it up. Get a Linux Image Running on the Target System You will need to have Linux running on your embedded system, in this case a Raspberry Pi. There are several choices for operating systems on the Raspberry Pi. We'll assume you are running the Raspbian Linux distribution as it is the most popular and recommended Linux for the Raspberry Pi. For a commercial embedded product you might want to look at Yocto (3) or boot2qt (4), which may be more suitable for an embedded Linux. If you don't already have Raspbian running on your Raspberry Pi, you can download the image from, uncompress it, and write it to a MicroSD card. At the time of writing, the latest Raspbian image file was 2016-05-27-raspbian-jessie.zip. I used these commands from a Linux shell to obtain and install it. Mkdir /raspi cd /raspi wget https: //downloads.raspberrypi.org/raspbian/images/raspbian-2016-05-31/2 2016-05-27-raspbian-jessie.zip sudo dd if = 2016 - 05 - 27 -raspbian -jessie.
Img of = /dev /mmcblk0 bs =4M You will need a suitably-sized MicroSD card to write the image in the step above (at least 8 GB, preferably more). On my laptop system I have an SD slot built in and it appears as the device /dev/mmcblk0. It may be different on your system, particularly if you use a USB to SD card adaptor. Be sure to use the correct device name or you may overwrite some other storage device on your system! Insert the MicroSD card in your Raspberry Pi and boot it up. You should perform the initial setup described on this Wiki page (5). Specifically, run the raspi-config program to set the system to boot to console and change the GPU memory to 256 MB.
While running raspi-config you'll probably also want to resize the MicroSD card, set the locale settings to something suitable for your location and keyboard layout, and enable ssh. You should also update to the latest Raspbian packages (run sudo apt-get update; sudo apt-get upgrade) and possibly configure WiFi (easily done from the desktop GUI) if you are using a Raspberry Pi 3. Then, as described in step 3 on the Wiki page, install the required development files and create the installation directory for Qt. Set Up the Toolchain/SDK The next step is to set up the toolchain to be able to cross-compile code for the Raspberry Pi on the desktop development computer. While you can compile natively on a Raspberry Pi, a modern desktop computer is at least an order of magnitude faster and will quickly pay off in time saved. Continue to follow the steps on the Wiki page (5) as they work well. I particularly like this procedure as it doesn't require repeatedly removing the SD card.
My Raspberry Pi is in a case that makes this awkward to do and risks damaging the ribbon cable for the touchscreen. Follow steps 4 through 6 of the Wiki page article. Your Raspberry Pi will need to be reachable over the network by ssh. After completing those steps you should now have a toolchain and the necessary files from the Raspberry Pi's root filesystem to be able to cross-compile software for it. Build a Cross-Compiled Qt Now let's build Qt for the Raspberry Pi. This is covered in steps 7 and 8 of the Wiki article. Note that I modified the procedure slightly.
Rather that using the source from git, I downloaded the official Qt 5.7.0 source distribution and built all of the Qt modules rather than just qtbase. It will initially take longer, but will provide you with everything you might need in the future. I used these commands to download, configure, and build Qt.

Wget http: //download.qt.io/officialreleases/qt/5.7/5.7.0/single/qt-everywhe xzf qt-everywhere-opensource-src-5.7.0.tar.gz cd qt -everywhere -opensource -src -5.7.0. /configure -release -opengl es2 -device linux -rasp -pi2 -g -device -option CROSSCOMPILE = /raspi /tools /arm -bcm2708 /gcc -linaro -arm -linux -gnueabihf -raspbian /bin /arm -linux -gnueabihf - -sysroot /raspi /sysroot -opensource -confirm -license -prefix /usr /local /qt5pi -extprefix /raspi /qt5pi -hostprefix /raspi /qt5 -v make make install You'll probably want to add a -j option to the make commands (e.g. Make -j4 on a four core CPU) as it will significantly speed up the build. (It may still take an hour or more depending on the speed of your computer.) You can choose to skip building some of the Qt modules if you wish. ( QtWebEngine is very large, for example.) I found one issue: the native rcc binary was missing from the SDK. You'll need this for building applications that use Qt resources. I simply copied the appropriate file into the right SDK bin directory. Cp /raspi /qtbase /bin /rcc /raspi /qt5pi /bin When the Qt build completes, run the rsync command (step 8 of the Wiki procedure) to install Qt on the Raspberry Pi.
At this point, you might want to test the toolchain and Qt install by following steps 9 through 12 in the Wiki article. If you are brave, you can assume it works and move straight to the next step. In any case, be sure to run step 11, which fixes up the OpenGL libraries used. Configure Qt Creator Now let's get to what this blog post is all about, configuring Qt Creator. We have a Raspberry Pi with Qt 5 and a toolchain running on our desktop. We can configure Qt Creator to make it easy to build and run Qt applications for the Raspberry Pi. Here's how to do this. First we need to add a device. Launch Qt Creator and select Tools / Options.
And then click on the Devices tab near the bottom left of the dialog. Click on Add. to open the Device Configuration Wizard. Select 'Generic Linux Device' and then Start Wizard. In the Connection screen, enter the appropriate parameters.
The screen shot below shows typical values. You will need to enter the appropriate host name or IP address for the Raspberry Pi on your network. Click Next and then Finish. The subsequent Device Test screen should confirm that Qt Creator can communicate with and log in to the Raspberry Pi. If not, go back and correct the settings. After clicking on Close you should see the board show up as a device, similar to the screen shot below: Next, add the cross-compiler.
From the Tools / Options. screen click on the Build & Run left tab and select Compilers. Click on Add / GCC and enter a new compiler with the name 'GCC (Raspberry Pi)' and the Compiler path set to /raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-g (you can click on Browse and navigate to the file). You should then see the new compiler listed, as in the following screen shot.
Next, select the Debuggers tab and add a new debugger. Click on Add, enter a suitable name, like 'gdb (Raspberry Pi)', and the path /raspi/tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf-gdb. The debugger entry should look similar to this: Now we can go to the Qt Versions tab of the Options screen. Check if an entry shows up with the qmake location set to /raspi/qt5/bin/qmake.
If not, click on Add., navigate to qmake, and give it a suitable version name. I used 'Qt 5.7.0 (Raspberry Pi)' as shown below. Finally, we are ready to combine these tools into what Qt Creator calls a kit. Click on the Options screen Kits tab, select Add, and create a kit using a suitable name, and the device, compiler, debugger, and Qt version we just created. The value of sysroot should be /raspi/sysroot and the other fields can be left empty. The kit I created is shown below. Test the Configuration and Start Embedded Development We're now ready to try a sample project!
Let's select File / New File or Project. And then select the template for Application and Qt Widgets Application. Click on Choose. And enter a project name or use the default. Then click on Next and select the desired kits.
Let's select both Desktop (or whatever kit you previously set up for native development) and Raspberry Pi. Click Next and leave the Class Information settings at their defaults. Hit Next one more time, use the default settings, and select Finish. We now have a project to test. I suggest you first build and run it locally on your desktop, which should be the default. Here's some of the code: The default project settings: Compiling it: And the example running on the desktop: If that works, click on the 'Raspberry Pi' kit under the Projects tab.
If you picked the same project type that I did, you'll need to add some lines to the qmake project file so that qmake knows what files must be deployed to the target system to run the application. An easy way to do this is to edit (from Qt Creator) the project file and add these lines at the bottom. INSTALLS = target target.

Files = widgettest target. Path = /home /pi If you go back to the Projects pane, and click on the Run button under 'Raspberry Pi' you should see a file now listed under 'Files to deploy:'. If you click on the build button, the project should successfully build using the Raspberry Pi kit.
Then, clicking on the run button should deploy and run the application on the Raspberry Pi. It won't look very impressive, just a full screen window since we didn't put any widgets in the application.
You might want to go back and add some widgets, like buttons, to the application and try running it again. You can do that from Qt Designer, available in the Design tab.
I suggest you try additional applications, either ones you may already have or some of the Qt examples and tutorials available from the Welcome tab in Qt Creator. You'll probably want to try a QML application, possibly using the Qt Quick Controls 2.
These should all work, although for most of them you will need to add some deployment rules like we did with the first example. Doing More The C debugger works much the same as when running an application locally, but will communicate with the debugger running on the target system through the network. Make sure you are using the Debug build configuration so you get symbolic debug information.
The valgrind profiler and memory analyzer functions should also work. The valgrind program needs to be installed on your Raspberry Pi (to do so, run sudo apt-get install valgrind). I had some issues running valgrind on certain Qt programs where it reported an error about unsupported ARM instructions. The QML profiler should also work. I aim to cover this in detail in a future blog post, but basically you select Analyze / QML Profiler, run your application until it exits or you stop it, and then see the results graphically. A typical screen shot is shown below. Summary These steps were valid at the time of writing but your mileage may vary if using different versions. The basic process should apply to other versions of Qt and other embedded boards. I have a Raspberry Pi 3 with on-board WiFi and the official touchscreen in a case.
It makes for a nice self-contained unit. It will even run for several hours when powered by a low-cost USB power bank. There are other tools available under Qt Creator that we don't have space to cover here.
If you take the time to configure Qt Creator and learn how to use it, I think you will appreciate how productive you can be for embedded development. I'm impressed that with Qt you can build and run your application locally on your desktop and then build, deploy and run the same code on an embedded board, all with just a few mouse clicks.
