Trying to compile gnome-libs - help...

[Michael Brodbelt <michael scorn org>]

Hi,

I've succesfully compiled and installed GTK, glib, and imlib, and I'm
trying to compile the gnome libraries next, but I keep getting an error. 
>From looking at the webpages, I thought this was caused by zlib (I have 
a RedHat 5 system, though it's been modified from base now), so I installed 
new rpm's, but I still have this trouble:-

ranlib .libs/libgtkxmhtml.a
creating libgtkxmhtml.la
(cd .libs && ln -s ../libgtkxmhtml.la libgtkxmhtml.la)
gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I./.. -I/usr/local/include

[root@mordor gnome-libs-0.27]# 

Any idea what causes this?

Zlib versions are:-

[root@mordor gnome-libs-0.27]# rpm -q zlib zlib-devel
zlib-1.1.2-2
zlib-devel-1.1.2-2

Any help would be appreciated,

Mike.
