buildGoPackage still needs a fix to not put all binaries into a subdirectory: |
|
The cross-compiled go compiler suffers from the same problem: @Ericson2314 I am pretty sure there is an easy fix to distinguish between a go compiler |

I wonder if we should remove the prefix already in the buildPhase in case someone breaks it by overriding installPhase?

@dtzWill is cross compilation for pkgsCross.musl64 something we aim for?
The go compiler would break in this case because ${GOHOSTOS}_${GOHOSTARCH} is equal to
${GOOS}_${GOARCH}, which means it would delete the go binaries in that case.

You could probably make make the condition GOOS != GOHOSTOS etc. since go doesn’t use a libc it’s kind of irrelevant here… but it should still work in the sense that you have a working compiler.

It does link against glibc for things like gethostbyname via nss modules.

Putting my thing another way, you can do either way (manual var or depsBuildBuild) the same way for !(build == host == target)
