Failure upon building project on Windows

gary-desroches opened this issue 4 years ago · comments

I'm attempting to build a new project using this template and Clang.

I followed the instructions to install the apps via choco, expect I already had Visual Studio Enterprise installed, so I skipped that bit. I added everything to the Path. I also added CC and CCX environment variables. I selected "Visual Studio 16 2019" as the generator, ClangCl as the Optional toolset, and checked "use default native compilers" Upon configuring in cmake-gui, I get the following output.

Selecting Windows SDK version 10.0.18362.0 to target Windows 10.0.18363.

@gary-desroches this appears to be a bug specific to building docopt.cpp on MSVC/Clang configuration. Have you been able to resolve this problem since you reported it?

@lefticus I managed to get the build process working on my Windows setup using MSVC/Clang. Unfortunately I'm pretty new to C++ and CMAKE and I don't have a proper solution for this but maybe this info can help someone more knowledgeable address this.

From what I could tell it seems that CMAKE_COMPILER_ID, which is "Clang" under these conditions results in a misconfiguration in build/conan.cmake around lines 154 and 174 which looks to be expecting the CMAKE_COMPILER_ID to be MSVC. I don't know if this is Conan making an incorrect assumption or some issue in this setup.

I managed to get everything building fine by setting the CMAKE_CXX_COMPILER_ID to MSVC and CMAKE_CXX_GENERATOR_TOOLSET to ClangCL before Conan.cmake invokes conan.cmake/conan_cmake_run() and it results in conan generating a working batch of settings that look something like this:

[settings]
arch=x86_64
arch_build=x86_64
build_type=Debug
compiler=Visual Studio
compiler.runtime=MDd
compiler.toolset=ClangCL
compiler.version=16
os=Windows
os_build=Windows
[options]
[build_requires]
[env]

I do revert the CMAKE_COMPILER_ID and CMAKE_GENERATOR_TOOLSET after this call but because I'm pretty clueless about most of this I'm not sure what the repercussions would be. I'm don't know if any of this is useful but hopefully someone here has an idea how this should be fixed up correctly.

For my own purposes I have worked around this by checking against these variables and modifying the cmake/Conan.cmake file to look something like this:

set (PROJECT_IS_MSVC_CLANG (${CMAKE_CXX_COMPILER_ID} STREQUAL "Clang" AND ${CMAKE_CXX_COMPILER_FRONTEND_VARIANT} STREQUAL "MSVC"))

if (PROJECT_IS_MSVC_CLANG)
  set(PREV_CMAKE_CXX_COMPILER_ID ${CMAKE_CXX_COMPILER_ID})
  set(PREV_CMAKE_CXX_GENERATOR_TOOLSET ${CMAKE_CXX_GENERATOR_TOOLSET})
  set(CMAKE_CXX_COMPILER_ID MSVC)
  set(CMAKE_CXX_GENERATOR_TOOLSET ClangCL)
endif ()  
  
conan_cmake_run(
  REQUIRES
  ${CONAN_EXTRA_REQUIRES}
  catch2/2.13.3
  docopt.cpp/0.6.2
  fmt/6.2.0
  spdlog/1.5.0
  OPTIONS
  ${CONAN_EXTRA_OPTIONS}
  BASIC_SETUP
  CMAKE_TARGETS # individual targets to link to
  BUILD
  missing)

if (PROJECT_IS_MSVC_CLANG)
  set(CMAKE_CXX_COMPILER_ID ${PREV_CMAKE_CXX_COMPILER_ID})
  set(CMAKE_CXX_GENERATOR_TOOLSET ${PREV_CMAKE_CXX_GENERATOR_TOOLSET})
endif ()

Probably a horrendous hack but it works for me until the conan packages handle this correctly.

Has anyone tried the fix proposed in #122 for this problem? I don't know if it works, but it looks a little cleaner.

I'm not able to reproduce this problem myself, otherwise I would try the fix.

I tried it, and I got the following error upon configuring.

Conan executing: C:/Program Files/Conan/conan/conan.exe install . -s build_type=Release -s compiler=clang -s compiler.version=11 -s compiler.libcxx=libc++ -e=CC= -e=CXX=C:/Program Files/LLVM/bin/clang-cl.exe -e=catch2/2.13.3 -e=docopt.cpp/0.6.2 -e=fmt/6.2.0 -e=spdlog/1.5.0 -g=cmake_multi --build=missing
ERROR: Invalid input 'catch2/2.13.3', use 'name=value'

Also, is this just setting environment variables to Clang? Setting them is a part of the instructions, so I already have them.

Edit: Actually, I had CC and CXX not the CMAKE_ versions. I set them as environment variables and tried again. I get the same errors, even the ones saying I'm missing those.

Not yet.

Has anyone tried using Conan profiles (https://docs.conan.io/en/latest/reference/profiles.html)? This is one of the approaches frequently suggested by people in the Conan community who are having trouble building with a specific toolchain. I think you can use a Conan profile to mimic what @BrendonSmuts was doing, without adding any compiler-specific code to Conan.cmake.

You would need to pass the path to your profile into cmake_conan_run:

conan_cmake_run(
    ...
    PROFILE ${PATH_TO_USER_CONAN_PROFILE}
    ...
)

I think you can use PROFILE default if the user doesn't have a Conan profile.

See https://github.com/conan-io/cmake-conan#profile and https://docs.conan.io/en/latest/using_packages/using_profiles.html for docs.

Edit: Whoops, seems like this is an ongoing issue with Conan and clang-cl, depending on the dependency you're building. According to this comment, (conan-io/conan#1839 (comment)), which includes a working clang-cl Conan profile, "some third-party Conan package recipes that we use haven't accounted for the possibility of compiler=clang when os=Windows".

I think we can close this issue now, as cpp-boilerplate-project has builds for windows/llvm
