[SOLVED] Coverity build in linux env (cmake project) is failing

Coverity build in linux env (cmake project) is failing

I am working on implementing the static code analyzer for our linux env code base and I am facing NO FILES EMITTED issue in it.

These are the steps I followed:

I have linux version Coverity 2023.9.2. We use cmake to build our projects with “Ninja” as the build system. I have configured Coverity with various templates in “myConfig.xml” file so that I don’t miss any compiler. My project is in C++ and C#.

Below is the command how I configure our cmake project before cov-build capture.

*az73@lin*:**/usr/bin/cmake -G "Ninja" -DCMAKE_BUILD_TYPE:STRING="Debug" -DCMAKE_INSTALL_PREFIX:PATH="/mnt/d/microservices/InteropServices/src/Services/Modules/HxGN.PPM.Interop.Readers/out/install/WSL-GCC-Debug" -DCMAKE_TOOLCHAIN_FILE="/mnt/d/microservices/repos/vcpkg/scripts/buildsystems/vcpkg.cmake" /mnt/d/microservices/InteropServices/src/Services/Modules/HxGN.PPM.Interop.Readers/CMakeLists.txt**

This is the cov-build command which I give while building the configured cmake project. (You can see that build is in progress without any issues)

*az73@lin*:**/mnt/d/microservices/InteropServices/src/Services/Modules/HxGN.PPM.Interop.Readers/build/WSL-GCC-Debug$ cov-build --dir cov-int --config /mnt/d/linux-coverity/cov-analysis-linux64-2023.9.2/bin/myConfig.xml /usr/bin/cmake --build /mnt/d/microservices/InteropServices/src/Services/Modules/HxGN.PPM.Interop.Readers/build/WSL-GCC-Debug --clean-first --config Debug**

And the error I have been facing is this:

**[WARNING] No files were emitted. This may be due to a problem with your configuration
or because no files were actually compiled by your build command.
Please make sure you have configured the compilers actually used in the compilation.**

When I tried for a sample cpp file which two issues, I could see that Coverity is able to capture it:

*az73@lin*:**/mnt/c/Users/ashaik2/Desktop$ cov-build --dir cov-int-samp --config /mnt/d/linux-coverity/cov-analysis-linux64-2023.9.2/bin/myConfig.xml g++ sample.cpp -o sample**

Emitted 1 C/C++ compilation units (100%) successfully

1 C/C++ compilation units (100%) are ready for analysis

I am not sure why Coverity is unable to emit any files when I am trying at project level. I would like to know if I am missing anything.

Solution

I have gone through the build-log and learned that the actual command during build is c++ -options file.cpp. c++ is an alias of g++ in linux env I guess. A cov-configure with c++ solved my problem and I can see cov-build emits files to get them analyzed.
