New comment by Chocimier on void-packages repository https://github.com/void-linux/void-packages/issues/31055#issuecomment-1012447457 Comment: Xbps behaviour seen here is that while installing `libgomp-devel`, it sees `cross-vpkg-dummy` currently installed with `provides=libgomp-devel`. So it wants to remove `cross-vpkg-dummy`. That, in turn, makes `libc.so` of shlib-provides not available, and transactions is declined. I think it would be enough to fix https://github.com/void-linux/xbps/issues/363. Then, `cross-vpkg-dummy` would satisfy dependency on `libgomp-devel`, not install it, and `cross-*-libc` files would be used during build.
