add mingw cross-compiler

[abeimler]

Hi, I was experimenting with gcc-mingw for ubuntu and cross-compiling. So I added gcc-mingw-w64 into setup-cpp.

It seems to work in a docker container and builds. pnpm build && docker build -f ./dev/docker/ubuntu_node.mingw.dockerfile -t setup_cpp:ubuntu-mingw .

TODOs:

• [x] ~~add powershell into setup-cpp - ./setup_cpp.js --powershell true (this is a task on it's own) [help wanted]~~ #105
  • need powershell for vcpkg (Could not find Z_VCPKG_BUILTIN_POWERSHELL_PATH using the following names powershell)
• [x] add more platforms
  • [x] Arch Linux: install mingw-w64 via AUR (We need something like setupAURPack)
  • [x] Fedora: install mingw64-gcc
  • [x] Windows: uses the already existing installation
• [ ] update alternatives and CC/CXX env. in Ubuntu ??? @aminya
  • Not sure about this one ... Do I really want to switch the compiler in on my HOST System ? (still good for docker and CI?)
• [x] ~~setup toolchain for cmake~~ - https://github.com/aminya/project_options/issues/140
  • need to setup triplets -DVCPKG_TARGET_TRIPLET="x64-mingw-dynamic" for vcpkg and cmake toolchain -DVCPKG_CHAINLOAD_TOOLCHAIN_FILE="/home/cmake/x86_64-w64-mingw32-toolchain.cmake"
• [ ] default version for Ubuntu etc. ??? - getVersion, DefaultUbuntuVersion, etc. @aminya
• [x] spellchecker and formatting

Notes:

• add new task in dev/cpp_vcpkg_project for testing

  mingw_build:
    - task: build_template
      vars:
        FEATURE_TESTS: OFF
        CMAKE_BUILD_TYPE: Release
        CONFIGURE_FLAGS: -DVCPKG_CHAINLOAD_TOOLCHAIN_FILE="/home/cmake/x86_64-w64-mingw32-toolchain.cmake" -DVCPKG_TARGET_TRIPLET="x64-mingw-dynamic"

LLVM installations fail on Ubuntu 22. The reason is that the default versions for LLVM don't include Ubuntu 22

Powershell support is added. Do you want to update this PR?

Yes ... Sry, I will update it later.

Note Docker (ubuntu-20.04, ubuntu_node.mingw.dockerfile, 14, 6, 0) fails, cuz dev/cpp_vcpkg_project didn't have this task:

  mingw_build:
    - task: build_template
      vars:
        FEATURE_TESTS: OFF
        CMAKE_BUILD_TYPE: Release
        CONFIGURE_FLAGS: -DVCPKG_CHAINLOAD_TOOLCHAIN_FILE="/home/cmake/x86_64-w64-mingw32.toolchain.cmake" -DVCPKG_TARGET_TRIPLET="x64-mingw-dynamic"

I added it for Testing in my local repo

I have some problems running yay (in the docker container)
ERROR: Running makepkg as root is not allowed as it can cause permanent, catastrophic damage to your system.

  // yay can't run as root, so skip update
  if (!didUpdate && aur != 'yay') {
    execRootSync(pacman, ["-Sy", "--noconfirm"])
    didUpdate = true
  }

  if (!didInit && aur != 'yay') {
    // install base-devel
    execRootSync(pacman, ["-Sy", "--noconfirm", "base-devel"])
    didInit = true
  }

I skip the update part, idk if this is OK. @aminya

I also did a big mistake in "update", change it to pacman -Sy .. x.x I'm sry

Not an fedora user, just installed mingw with setupDnfPack("mingw64-gcc", version).

Have some problem building the example:

Could you make a PR to add the MinGW toolchain in project_options?

[abeimler]

I fixed the docker builds and add fedora- and arch-linux-support. Seems to work when I test it with pnpm run test.docker.ubuntu.mingw, pnpm run test.docker.fedora.mingw and pnpm run test.docker.arch.mingw

tbh I don't really know how, I can add a cmake/toolchains-folder, but then what. This needs to be done in https://github.com/aminya/project_options/issues/140

When using vcpkg, for a successful build I need to add some flags: -DVCPKG_CHAINLOAD_TOOLCHAIN_FILE="/home/cmake/toolchains/x86_64-w64-mingw32.toolchain.cmake" -DVCPKG_TARGET_TRIPLET="x64-mingw-dynamic" (idk about conan...)

• [x] Waiting for build_cross_mingw task.

Installing mingw (in linux) itself seems to work ... but installing powershell in arch or building the cpp example in fedora didn't work.

1. Ubuntu-Mingw Build (+ powershell):

2. Arch-Mingw Build (without powershell):

2.1. Arch-Mingw (+ powershell):

3. Fedora-Mingw (+ powershell):

[abeimler]

@aminya For the "arch linux + yay"-Problem, I would suggest to auto-detect some popular AUR-Helper/pacman wrapper.

A CLI option for arch-linux-user would be also nice:

--pacman-wrapper yay

We can comment out the Fedora Mingw and Arch Mingw inside CI for now if the errors are not fixable.

agree, the powershell problem is a bug of its own and for the fedora error, I need to do more testing with project_options (MinGW installation works though)
