just a tip for you. [target.x86_64-pc-windows-gnu]
dockerfile = "Dockerfile"would automatically build the dockerfile for you. But also it could be replaced with [target.x86_64-pc-windows-gnu]
image = "ghcr.io/cross-rs/x86_64-pc-windows-gnu:main"
pre-build = ["apt-get update && apt-get install --assume-yes --no-install-recommends libclang-dev clang"] |

This is partially a duplicate of #1112, and also linked to #1110. However, there's still issues afterwards. The relevant part of the log is below, and as we can see, the toolchain and CMake configuration is done, however, the build script is now unable to find This should be part of the search path, but oddly, it's not found: $ `x86_64-w64-mingw32-gcc-posix -print-prog-name=cc1plus` -v

End of search list.We might need to modify the bindgen sysroot or something. EDIT: A similar issue seems to occur on Here, for some reason, it's trying to include the host |

I've run into a similar case in: where I get a stack trace of: On a native runner, just installing multilib is sufficient there, but here, I can't seem to get this to work unfortunately: [workspace.metadata.cross.target.aarch64-unknown-linux-gnu]
pre-build = [
"dpkg --add-architecture $CROSS_DEB_ARCH",
"apt update && apt install -y g++ g++-multilib libclang-dev clang"
]
[workspace.metadata.cross.target.armv7-unknown-linux-gnueabihf]
pre-build = [
"dpkg --add-architecture $CROSS_DEB_ARCH",
"apt update && apt install -y g++ g++-multilib libclang-dev clang"
]I tried going extra with dependencies, e.g. [workspace.metadata.cross.target.aarch64-unknown-linux-gnu]
pre-build = [
"dpkg --add-architecture $CROSS_DEB_ARCH",
"apt install -y g++:$CROSS_DEB_ARCH gcc:$CROSS_DEB_ARCH g++-9:$CROSS_DEB_ARCH gcc-9:$CROSS_DEB_ARCH cpp:$CROSS_DEB_ARCH binutils:$CROSS_DEB_ARCH"
]But that didn't do the trick either. |
