ok, maybe this is now working? can you try..
# setenv GOPATH /usr/local
# go get github.com/andlabs/ui
(barfs with errors as you mentioned)
cd /usr/local/src/github.com/andlabs/ui
take a look at the cgo specs in uitask_unix.go for example:
// #cgo pkg-config: gtk+-3.0
// #cgo CFLAGS: --std=c99
// #include "gtk_unix.h"
// extern gboolean xdoissue(gpointer data);
import "C"
it's using pkg-config to get the CFLAGS, LDFLAGS etc.. so it should work.
I think there is an issue with cgo using 'cc' when it is undefined... try this?
# cd /usr/local/src/github.com/andlabs/ui
# setenv CC clang
# go build
(wait .. hey there are no more errors, YAY)
# cd examples/basicwindow
# go build
# ./basicwindow
* a window pops up *
OK so i think this is working with setenv CC clang (or use export
depending on your shell)
{ but I'd change your CXX to clang++ }
