Compiler OS go packages

[jakirkham]

Appears there are builds of the compiler OS go packages for OSes they shouldn't be used on. For example, go_linux-64 is not only available on Linux, but also on macOS and Windows. This is also true of go_osx-64 and go_win-64. In fact there are no Windows builds of go_win-64.

Go generates static binaries and is capable of doing so cross-platform. On Linux, I can do:

# Install the cross-compiler
$ conda install -y go_win-64

# Hello world!
$ cat <<EOF > hw.go
package main

import "fmt"

func main() {
    fmt.Printf("Hello, World!\n")
}
EOF

# Re-check target platform
$ env | grep -i GOOS=
GOOS=windows

# Build the exe
$ go build hw.go

# What did I build?
$ file hw.exe
hw.exe: PE32+ executable (console) x86-64 (stripped to external PDB), for MS Windows

[nehaljwani]

I can run it too ;-)

$ wine64 hw.exe
hello world

[jakirkham]

I see. So they are for cross-compilation?

[nehaljwani]

Indeed.

Known issue ( conda-forge/conda-forge-ci-setup-feedstock#14 ). We have had a hard time fixing it. If you would like to take a look, we would certainly appreciate the help. Interestingly it does not block uploading.

I deprecated the cross compiler go packages. If we need this again lets open an issue.
