Hi there,  
not sure why but gtksourceview seems to give me slight problems. The  
other ruby-gnome bindings work well, i.e. buttons etc… are all working,  
just not getting ruby-gtksourceview to compile.

Maybe one of you has a hint that can help me.

For the record, I am using latest CVS checkout of ruby-gnome module.

In /usr/lib I have these gktsourceview relevant files:

libgtksourceview-1.0.la libgtksourceview-1.0.so.0  
libgtksourceview-2.0.la libgtksourceview-2.0.so.0  
libgtksourceview-1.0.so libgtksourceview-1.0.so.0.0.0  
libgtksourceview-2.0.so libgtksourceview-2.0.so.0.0.0

In /usr/include I have both gtksourceview-1.0 and gtksourceview-2.0.  
Removing gtksourceview-2.0 from  
/usr/lib and /usr/include does not influence anything.

My Gcc Version is: gcc 4.2.0

Now to the error of the rubygnome binding, running the following in  
gtksourceview/ directory:  
ruby extconf.rb

Results into:

checking for GCC… yes  
checking for rb\_define\_alloc\_func()… yes  
checking for rb\_block\_proc()… yes  
checking for new allocation framework… yes  
checking for attribute assignment… aliayes

Could not create Makefile due to some reason, probably lack of

You may need to install a dev package of gtksourceview.  
What the result of pkg-config ?

$ pkg-config gtksourceview-1.0 --libs --cflags --modversion

If it returns error messages, check it carefully.
