Additional context

Hi, I know this is a duplicate of #35500, but in this case my VCPKG_BUILD_TYPE=release. What should I do?

dg0yt commented 2 months ago

The title states "with debug-only triplet", but the post says "VCPKG_BUILD_TYPE=release". The log shows both types are built.

The triplet has an unusual combination: dynamic linrary linkage, static CRT linkage. Is this intentional?

The toolchain customizes cmake root path settings. Maybe this has undesired side effects

What should I do?

Check logs from buildtrees/boost-stacktrace.

FTR boost-stacktrace:x64-mingw-dynamic builds successfully, on a linux host.

Neumann-A commented 2 months ago

boost-build/boost-modular-build.cmake

Also means older boost version

pfhgil commented 2 months ago

Sorry for the confusion about build types. Now it's definitely equals to "release" and builds for release (checked in the log). I also modified the cmake file of my toolchain and triplet. Now my triplet differs from the standard x64-mingw-dynamic triplet only in setting the build type and installing the toolchain.

My triplet (sg-x64-mingw-dynamic-release.cmake):

set(VCPKG_CHAINLOAD_TOOLCHAIN_FILE "/home/ilya/pixelfield/test-windows/cmake/mingw.cmake")

set(VCPKG_TARGET_ARCHITECTURE x64)
set(VCPKG_CRT_LINKAGE dynamic)
set(VCPKG_LIBRARY_LINKAGE dynamic)
set(VCPKG_ENV_PASSTHROUGH PATH)

set(VCPKG_CMAKE_SYSTEM_NAME MinGW)
set(VCPKG_POLICY_DLLS_WITHOUT_LIBS enabled)
set(VCPKG_BUILD_TYPE release)

My toolchain (mingw.cmake):

set(CMAKE_C_COMPILER "$ENV{SUNGEAR_LLVM_MINGW_PATH}/bin/x86_64-w64-mingw32-clang")
set(CMAKE_CXX_COMPILER "$ENV{SUNGEAR_LLVM_MINGW_PATH}/bin/x86_64-w64-mingw32-clang++")
set(CMAKE_ASM_COMPILER "$ENV{SUNGEAR_LLVM_MINGW_PATH}/bin/x86_64-w64-mingw32-clang")
set(CMAKE_RC_COMPILER "$ENV{SUNGEAR_LLVM_MINGW_PATH}/bin/llvm-rc")

I also indicate a preset for the build, which I did not indicate earlier:

{
      "binaryDir": "cmake-build-release-mingw-x86-64",
      "generator": "Ninja",
      "name": "x86-64-mingw-release",
      "cacheVariables": {
        "CMAKE_SYSTEM_NAME" : "MinGW",
        "CMAKE_SYSTEM_PROCESSOR": "x64",
        "CMAKE_BUILD_TYPE": "Release",
        "SG_BUILD_PRESET": "x86-64-mingw-release",

        "VCPKG_OVERLAY_TRIPLETS" : "/home/ilya/pixelfield/test-windows/vcpkg-triplets",
        "VCPKG_TARGET_TRIPLET" : "sg-x64-mingw-dynamic-release",
        "CMAKE_TOOLCHAIN_FILE" : "$env{VCPKG_ROOT}/scripts/buildsystems/vcpkg.cmake"
      }

Now I get the following errors (it seems like the package is being built in the wrong C++ standard location):

Sorry for the possibly stupid questions, I'm still new to cross-compiling projects

dg0yt commented 2 months ago

It is pullling wrong headers, indeed. And the compiler is called with -march=i686 --target=i386-pc-linux which might be less mingw than expected.

Maybe it is better to make yourself familiar with cross-compiling and mingw in more usual setups? You could create your chainloaded toolchain file from the standard mingw.cmake. And there was the hint that you should pull the latest vcpkg changes. The vcpkg boost ports use CMake now.

pfhgil commented 2 months ago

I updated vcpkg, but the cause of the error seems to remain the same. I can’t use the standard x64-mingw-dynamic triplet because spdlog will not be build, which apparently requires the posix multithreading model (it doesn’t find std::thread, std::mutex, etc.), and when using the x64-mingw-dynamic triplet, it seems that a toolchain with a win32 model is used.

My triplet, toolchain and CMakePresets remain unchanged.

The mingw triplets don't enforce a particular multithreading model. It is up to your mingw installation. But many packages simply require C++ features which are only provided with the posix model.

pfhgil commented 2 months ago

Sorry, but this does not solve my problem with llvm-mingw and the reason for the error remains unclear. You're just advising me to use the standard x64-mingw-dynamic. Or did I misunderstand you?

dg0yt commented 2 months ago

my problem with llvm-mingw and the reason for the error remains unclear.

There is still -march=i686 --target=i386-pc-linux. I don't know where it comes from, but I would really expect mingw or win32 instead of linux there.
