[package] glew/2.2.0: The GLEW library

[rudolfheszele]

Description

Looks like the package cannot be built on Windows using clang.
Here is the profile I am using:

[settings]
arch=x86_64
build_type=Debug
compiler=clang
compiler.cppstd=20
compiler.version=19
compiler.libcxx=libstdc++11

[buildenv]

tools.cmake.cmaketoolchain:generator=Ninja
tools.cmake.cmaketoolchain:extra_variables={'CMAKE_EXPORT_COMPILE_COMMANDS': '1'}
tools.build:compiler_executables={'c': 'clang', 'cpp': 'clang++'}

When invoking conan install wirth --build=missing is start building glew, but it fails with the following error message:

ninja: build stopped: subcommand failed.

I think it is actually an issue with the CMakeLists.txt file in the original repository, since it always includes .rc files on Windows, and probably they should only be included with MSVC. I did a quick test locally and then it worked with clang if those .rc files were not included.

[rudolfheszele]

I made a pull request on the glew repository with the proposed fix: nigels-com/glew#428

[jcar87]

Hi @rudolfheszele - thanks so much for opening this issue and even more so for reaching out to upstream.

However, I can see that CMake is correctly using llvm-rc to process the file - I think the logic in is perfectly valid if CMake knows to redirect the compilation to the resource compiler regardless of the compiler.

The issue seems similar to this: curl/curl#7765 , where it has issues with the unicode copyright character
