beginner coder here.
I'm trying to set up gtk+ to set up a GUI for a program. I'm following the procedure section of these instructions: https://wiki.gnome.org/Projects/GTK+/OSX/Building
I have downloaded the code they provide, but cannot get further than that. I am attaching a screenshot of commands that I ran and the error that I got.
If anyone has any ideas, would really appreciate any help.
