MSVC target on Windows does not work with any C++ code #18685

Open vdemichev opened 10 months ago

vdemichev commented 10 months ago

Zig Version

0.11.0, x64 Windows; same problem with the latest master

Steps to Reproduce and Observed Behavior

Create any cpp file, try to compile with -target native-native-msvc - does not work. Target gnu works fine. Compiling as C code works fine.

Output:

PS C:\Temp\Test> gc test.cpp
#include <iostream>

int main() {
        std::cout << "Hello World!\n";
        return 0;
}
PS C:\Temp\Test> zig version
0.11.0
PS C:\Temp\Test> zig c++ C:/temp/test/test.cpp -target native-native-msvc

Expected Behavior

I guess it should work? My goal is try to compile a project that relies on third-party code that is MSVC-specific.

kassane commented 7 months ago

Please, try replacing to zig cc over zig c++ or zig build-exe -lc no -lc++

Zig toolchain can't build libcxx for MSVC yet.

Hey I experience the same issue I depend on c++ project (Whisper.cpp) and it failed to build / link with the same error with zig and MSVC. How can I still use it? if I remove -lc++ then It failed with undefined external symbols

Yes! Currently, replace -lc++ to -lc on Windows host with winSDK and VC++buildtools installed to zig-clang detect files (include & libs). How? checking, run zig libc to see vcruntimelib on msvc_lib_dir.

And cross-compile (linux/macos to windows-msvc), try use xwin to download include & libs, like https://github.com/kassane/xwin-zig-test

Yes!

You mean it's possible with MSVC + zig + whisper.cpp?

Currently, replace -lc++ to -lc

But then it failed to compile because of missing symbols

Windows host with winSDK and VC++buildtools

I have both

zig-clang detect files (include & libs)

What do you mean?
