Examples of PVS-Studio integration in QMake (QtCreator)
For PVS-Studio analyzer integration into your project, you can use the PVS-Studio.pri module.
A few examples in this repository will help you learn how to use the QMake module in your project properly.
- Connect the .pri module to your project;
- Add a new configuration, for example, "Analyze";
- In settings of the configuration "Build Steps" -> "Make arguments", add the name of the target (pvs_studio.target = this_name);
- Switch to the created configuration and run "Build All";
- See the results in the analyzer in the Issues Panel.
Analysis without integration (Linux only)
This utility requires the strace utility.
This can be built with the help of the command:
pvs-studio-analyzer trace -- qmake
You can use any other build command with all the necessary parameters instead of make, for example:
pvs-studio-analyzer trace -- qmake debug
After you build your project, you should execute the commands:
pvs-studio-analyzer analyze -o /path/to/project.log -e /path/to/exclude-path -j<N> plog-converter -a GA:1,2 -t tasklist -o /path/to/project.tasks /path/to/project.log
Analyzer warnings will be saved into the specified project.tasks file.
If your project isn't CMake or you have problems with the strace utility, you may try generating the file compile_commands.json with the help of the Bear utility. This file will help the analyzer to check a project successfully only in cases where the environment variables don't influence the file compilation.
If you use cross compilers
In this case, the compilers may have special names and the analyzer will not be able to find them. To analyze such a project, you must explicitly list the names of the compilers without the paths:
pvs-studio-analyzer analyze ... --compiler COMPILER_NAME --compiler COMPILER_NAME ... plog-converter ...
Also, when you use cross compilers, the directory with the header files of the compiler will be changed. It's necessary to exclude such directories from the analysis with the help of
-e flag, so that the analyzer doesn't issue warnings for these files.
pvs-studio-analyzer ... -e /path/to/exclude-path ...
There shouldn't be any issues with the cross compilers during the integration of the analyzer into the build system.
