    Description

      Hello,

      I'm working on a bazel project where compile_commands.json are generated.

      I'm using the `compile_commands.json` (AKA Compilation Database file) project to open it.

      I'm getting this kind of error messages (one per source file) whenever I'm opening it.

      Compiler feature detection failure!

      It seems that QtCreator tries somehow to use the host compiler while the `compile_commands.json` points to something else. And of course the host compiler doesn't recognize

      gcc: error: unrecognized command-line option '-mfloat-abi=soft' 
gcc: error: unrecognized command-line option '-mno-unaligned-access' 
gcc: error: unrecognized command-line option '-mthumb'

      Since this is an x86 machine.

      I also try to make an ARM kit where I selected the arm cross compiler for C and C++ but it isn't taken either

       

      I think the best solution would be to use the compiler from the kit to detect the compiler feature.

       

      Can we fix this?

       

      Many thanks.

       

      Laurent
