Installing on Mac OS-X os a convoluted process

[jaytaylor]

"Don't forget, that you need the GTK-Development-Packages." isn't particularly helpful.

Please update the docs to include the following info for mac users:

# Install dependencies.
$ brew install cairo pixman fontconfig freetype libpng gtksourceview

# Ensure they can be found by exporting the PKG_CONFIG_PATH.
$ export PKG_CONFIG_PATH=":/usr/local/opt/cairo/lib/pkgconfig:/usr/local/opt/pixman/lib/pkgconfig:/usr/local/opt/fontconfig/lib/pkgconfig:/usr/local/opt/freetype/lib/pkgconfig:/usr/local/opt/libpng/lib/pkgconfig:/usr/X11/lib/pkgconfig:/usr/local/opt/gtksourceview/lib/pkgconfig:${PKG_CONFIG_PATH}"

$ make all

Hi,

I'm trying to install the package, with

go get github.com/mattn/go-gtk

and I get

# github.com/mattn/go-gtk/pango
clang: error: argument unused during compilation: '-fno-eliminate-unused-debug-types'
# github.com/mattn/go-gtk/glib
clang: error: argument unused during compilation: '-fno-eliminate-unused-debug-types'
# github.com/mattn/go-gtk/gdk
clang: error: argument unused during compilation: '-fno-eliminate-unused-debug-types'

if I clone the repo. and then

make all

cd pango && go get -x

Not sure why, could you please help? Thanks!

[mattn]

Could you please try: CC=gcc go get github.com/mattn/go-gtk ? Probably your go is using clang?

[allochi]

Thanks! Sorry, I didn't check my emails, now I get this:

can't load package: package github.com/mattn/go-gtk: no Go source files in /Users/allochi/Projects/gocode/src/github.com/mattn/go-gtk

Clang is default compiler on os x 10.9, gcc is only symbolic link to it. You have to install gcc to use go's C package:

sudo port install gcc49
sudo ln -nsf $(which gcc-4.9) /usr/bin/gcc

You also need to meet some dependencies which I still haven't met. I'll report if I manage to do that.

I managed to run it on OS X 10.9. There is how it looks:

I used macports to install all dependancies. Some of them were:

sudo port install gtk2
sudo port install gdk-pixbuf2
brew install pango

XQuartz is also needed, couple other things probably too. Compilation of everything took about 2-3 hours.

Compilation of everything took about 2-3 hours.

:-(

Are the dependencies listed just to compile, as in distributed compiled apps only need macs with XQuartz to run? I ask as I might write some software using this. Asking users to install XQuartz isn't bad, asking them to compile libraries is another matter.

Thanks.

[solusipse]

You don't have to ask them to compile libraries on their own, you can provide them with your program. XQuartz isn't also always needed. I found some informations on this subject (but haven't tested): http://bfwiki.tellefsen.net/index.php/Building_a_native_(no_X11)_MacOSX_binary https://github.com/conformal/gotk3/wiki/Installing-on-OSX#osx-native
