Error

After running make or trying to just run go get github.com/lxc/lxd . The gettext errors are produced as shown below.

Fix

Tell cgo to link libintl by changing line 26 of gettext.go from /* to

// #cgo LDFLAGS: -lintl

and then insert /* into line 27 of the same file.

I have not experimented this until very recently on a mac, and your line solved the problem. However it does not compile on Fedora, I still don't know the reason but I added a comment with your solution. I'm gonna keep this open because this is not really fixed. Thanks!

To fix a similar issue on osx, use this instead:

The error:

./gettext.go:29:10: fatal error: 'libintl.h' file not found

The fix:

Install gettext with homebrew brew install gettext

Update gettext.go

// Package gettext provides bindings for GNU Gettext.
package gettext

/*
#cgo LDFLAGS: -L/usr/local/opt/gettext/lib -lintl
#cgo CPPFLAGS: -I/usr/local/opt/gettext/include

#include <libintl.h>

#include <locale.h>
#include <stdlib.h>
*/
import "C" 

import (
    "fmt"
    "strings"
    "unsafe"
)

[Slach]

for cygwin install gettext, gettext-devel and libintl-devel packages
and add following lines

#cgo LDFLAGS: -L/cygdrive/c/cygwin/lib
#cgo LDFLAGS: -lintl
#cgo CPPFLAGS: -I/cygdrive/c/cygwin/usr/include

Also see I get a linker error “undefined reference to libintl_gettext” in the GetText FAQ.
