# @BLURB: An eclass for GoLang packages not installed inside GOPATH/GOBIN.
|
|
# @DESCRIPTION:
|
|
# This eclass allows to install arbitrary packages written in GoLang which
|
|
# don't support being installed inside the Go environment.
|
|
# This mostly includes traditional packages (C/C++/GUI) embedding tools written
|
|
# in GoLang, and GoLang packages that need to be compiled with GCC instead of
|
|
# the standard Go interpreter.
|
|
#
|
|
# @EXAMPLE:
|
|
# Typical ebuild using golang-single.eclass:
|
|
#
|
|
# @CODE
|
|
# EAPI=5
|
|
