CompilerIdC/a.exe cannot be read

Hello,

I still can’t get my conan-glew package to build with MinGW. I have created a develop branch, in which I corrected the errors I had last time I wrote. But now when I execute:

conan test_package -s compiler=gcc -s compiler.version=5.3 -s compiler.libcxx=libstdc++

(in a command prompt, after I set the path to include Mingw/bin - cmake doesn’t like msys any more)

I get the following error:

CMake Error at C:/Program Files/CMake/share/cmake-3.8/Modules/CMakeDetermineCompilerId.cmake:454 (file):

  cannot be read.

I would appreciate any idea about how I could resolve this 😸

Thanks,

Dimitri

Yes, I copy-pasted the build function from your message, with just a couple of modifications to match my imports. (I did read the documentation first though, I promise 😄 )

I always make sure I am running the latest version of conan. The Visual Studio build worked on my machine too, after I added that little echo hack I mention in my previous message. Before, I was getting an error that the “&& devenv …” command could not be executed (because it was starting with && I suppose). Now it works locally but not on appveyor, but that’s another issue and I haven’t looked into it yet.

As far as mingw is concerned, you’re right. I should try a build without conan first.

Oh I see… I made a little mistake about which command comes from what. But I understand it now. So it makes sense, but it would indeed still help, if it returned an echo or something…
