Description

It seems that, for Windows platforms, the libnethost.lib static library shipped with the .NET SDK is built with LTCG enabled, rendering it entirely unusable by non-MSVC toolchains such as Zig or just plain LLD on its own.

I'm not sure LTCG meaningfully benefits libnethost anyway, so I would argue it should just be disabled here.

Reproduction Steps

#define NETHOST_USE_AS_STATIC

#include "nethost.h"

int main()
{
    char_t buffer[4096];
    size_t buffer_size = sizeof(buffer) / sizeof(char_t);

    (void)get_hostfxr_path(buffer, &buffer_size, NULL);
}

zig cc test.c /path/to/libnethost.lib

Expected behavior

The program should link successfully.

Actual behavior

$ zig cc test.c libnethost.lib
lld-link: error: unknown file type: nethost\CMakeFiles\libnethost.dir\nethost.cpp.obj

Regression?

No.

Known Workarounds

Building from source with LTCG off (presumably), but this is a pretty big inconvenience.

Configuration

• .NET SDK 6.0.6
• Windows x64
