Multiple compilers, ConanMultiPackager and CMake troubles

Hi!

I wish to package multiple packages for Linux x64, compiler with GCC/Clang.

To do so, I have two terminals. One has env vars CONAN_GCC_VERSIONS & cie, the other has the Clang variables.

The problem is that the chosen compiler (clang) is not detected by CMake when running test_package. Here is the output I get:

– The C compiler identification is GNU 7.2.0 – The CXX compiler identification is GNU 7.2.0 – Check for working C compiler: /usr/bin/cc – Check for working C compiler: /usr/bin/cc – works – Detecting C compiler ABI info – Detecting C compiler ABI info - done – Detecting C compile features – Detecting C compile features - done – Check for working CXX compiler: /usr/bin/c++ – Check for working CXX compiler: /usr/bin/c++ – works – Detecting CXX compiler ABI info – Detecting CXX compiler ABI info - done – Detecting CXX compile features – Detecting CXX compile features - done – Conan: called by CMake conan helper CMake Error at build/9fad4defe7e3af96f74f9172f136f8e10e7bf90a/conanbuildinfo.cmake:381 (message): Incorrect ‘clang’, is not the one detected by CMake: ‘GNU’

When creating a single package with conan create theo/stable -pr clang50, everything works fine:

– The C compiler identification is Clang 5.0.0 – The CXX compiler identification is Clang 5.0.0 – Check for working C compiler: /usr/bin/clang – Check for working C compiler: /usr/bin/clang – works – Detecting C compiler ABI info – Detecting C compiler ABI info - done – Detecting C compile features – Detecting C compile features - done – Check for working CXX compiler: /usr/bin/clang++ – Check for working CXX compiler: /usr/bin/clang++ – works

Upgrade and try!

The @uilianries fix to iterate the builds and alter the env sounds good to me, not very hacky. I’m going to try the approach of passing a profile and will report again.
