Possible to allow msvcrtd linking for static builds in debug mode?

[star69rem]

The latest version of Librashader is very nice. It's much easier to compile static release builds now. I'm wondering if anything has changed where it might be possible to allow for debug static builds now. See rust-lang/rust#122268 and rust-lang/rust#39016 for reference.

Currently when you build librashader in debug mode, it still links msvcrt in release mode I think.

I’m not sure what code changes are actually needed for this. librashader-build-script can take arbitrary cargo flags, or you can just build with cargo directly (the build-script does nothing special but move files around)

It looks like it's glslang related.

Maybe glslang is missing a debug flag?

This is what cc says.

Perhaps try building with the environment variable DEBUG=1 set?

Same thing with DEBUG=1.

rust-lang/rust#122268 (comment)

Does doing whats indicated here work?

[chyyran]

This is blocking on support in cc. See rust-lang/cc-rs#1230.

Once cc updates spirv-cross2 and glslang will also need updates.
