[gtkextra] Problem with installation..

[Emre I. <ei...@pa...>]

I suppose this mailing list is not for troubleshooting, but I'll be very
happy if anyone would help me:

I use Slackware 7.1 with Gnome and have already 
gtk+ 2.1.8, gtk+extra 0.99.14, Python 2.1, Numerical Python
installed. After configuring the installation of the source sg-0.6.3
of SciGraphica, the "make" operation gives errors after many successful
"gcc" operations. The errors are alike:

sg.../src/sg_worksheet.c: undefined reference to gtk_sheet_get_type

and many other "undefined reference"s.

What should I do? I hope someone would help..
