Re: [GtkGLExt] 回复： help

[John Darrington <john darrington wattle id au>]

If you really must use that particular version of gtkglext, my advice would be 
to carefully read through the release notes of that version.  And note what versions
of Pango and Gtk+ they require.  Then build against *those* versions *and no later version*.

For example if it says "Pango 1.2 or later", use 1.2 exactly, not a later version.

I realise this is a very non-ideal situation, but unfortunately there are  a lot of compatibility 
issues with gtk libraries :(

     I  just want to use the gtkglext of version 1.0.6, but it doesn't provide the pre-compiled version.
     
     
     I have treid so many days to compile an install the gtkglext-1.0.6. At last, I give up. I have to use 
the pre-compiled version of 1.2.0 thought it's not I want.
     
     
     Thank you~~

     I am not sure, but I think this is because of version mismatches between GtkGlExt and other libraries.
     
     You need an older version of pango and gtk+ OR a newer version of GtkGlExt.  o
     
     Or just use the pre-compiled version which comes with your operating system.

          hi~
          I am a student and now I am using the gtkglext in linux (Fedora), and I have some problems. So I 
Want to get some help from you, thank you very much ^_^
          
          I download the source code gtkglext-1.0.6, as README tells, I compile and install it.
          Here is my command lines and results:
          # ./configure --prefix=/usr
          ...
          configuration:
              OpenGL CFLAGS:        
              OpenGL LIBS:         -lGLU -lGL
              multihead support:    yes
              debug:            minimum
              extra defs: 
          # make
          ...
          # make install
          ...
          Till now,everything seems good (no error is proposed). But when I use the command line "make 
examples",there are some link errors:
          ../gdk/.libs/libgdkglext-x11-1.0.so: undefined reference to `pango_x_font_subfont_xlfd'
