Coverity and ESP32-projects

Hi,
Anyone managed to get Coverity to accept your project? When running cov-build all I get is:
Code: Select all
[WARNING] No files were emitted. This may be due to a problem with your configuration
The build process completes like it always do.
I ran Coverity as follows:
Code: Select all
make clean
cov-configure --compiler /home/permal/esp/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc --gcc
cov-build --dir cov-int make -j8

I am interested in using Coverity at some stage, so if you find a solution please return and let us know.

I've not tried again since my initial post so no status change on my end.

I've faced similar issue and found solution. In my case I've found some hints in coverity logs:
[Codebox]This /home/xxxx/.espressif/tools/xtensa-esp32-elf/esp-2019r2-8.2.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc compiler command specifies the following arguments which should be marked as required in your configuration:
-mlongcalls -std=gnu99
Please reconfigure this compiler as follows:
cov-configure -co /home/xxxx/.espressif/tools/xtensa-esp32-elf/esp-2019r2-8.2.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc -- -mlongcalls -std=gnu99
or create a template configuration for it (recommended).

So I've configured compiler as recommended
[Codebox]cov-configure -co /home/xxxx/.espressif/tools/xtensa-esp32-elf/esp-2019r2-8.2.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc -- -mlongcalls -std=gnu99[/Codebox]
And there is not different message at the end of compilation:
[Codebox]974 C/C++ compilation units (100%) are ready for analysis
The cov-build utility completed successfully.[/Codebox]
Hope that helps
