[Pkg-golang-devel] Bug#776401: src:golang: Set CGO_ENABLED for all platforms

[Hilko Bengen]

Package: src:golang
Severity: wishlist
Version: 2:1.3.3-1
Tags: patch

Apparently, it is possible to build a CGO-enabled Golang cross compiler
on all platforms if CGO_ENABLED=1 is set at build-time. I have
successfully built Windows executables that use fopen(), fread()
functions from the C standard library using something like:

$ CC=i686-w64-mingw32-gcc CGO_ENABLED=1 GOOS=windows GOARCH=i386 go build ...

Please consider adding the simple patch attached below.

(I am still trying to figure out if there's a way to set a
GOARCH/GOOS-specific sensible default for CC, CXX.)

Cheers,
-Hilko
