All it does is create a menu. However, when I tried to use AGUP, I get a bunch of linker errors:
[Linker error] undefined reference to `agtk_theme'
[Linker error] undefined reference to `agup_init(AGUP_THEME const*)'
..and so on. Is there a library that I can link to my project for agup? Because I cannot seem to find one.
]]>If you have the source version of this library, build it first. Then you should be able to link with it.
]]>I have no idea how to build a library, I've always used DevPaks.
I found an agup devpak, one that included the libagup.a, but I still have the same problem even after linking the library.
]]>Same problem? Or some other problem?
]]>It's fixed. agup is a library written in C, so it was compiled in C. All I have to do is:
extern "C"{ #include <agup.h> }
And it works fine.
]]>That extern "C" should ideally be inside agup.h, so nobody else trips on it. Headers are great for hiding verbiage like this.
