[gtkada] Building on Fedora 8

[R. B. Love]

My goal is to eventually build GPS for my system but I'm hung up on 
getting the SVN source of GTKADA to build.  I'll take all advice gladly.

When I run configure, I get this result:

checking for pkg-config... /usr/bin/pkg-config
checking for GTK - version >= 2.2.0... no
*** Could not run GTK test program, checking why...
*** The test program failed to compile or link. See the file config.log 
for the
*** exact error that occured. This usually means GTK was incorrectly 
installed
*** or that you have moved GTK since it was installed.

As far as I know, the default GTK+ that came with the system is here 
untouched:
rlove at falcon> rpm -q gtk2
gtk2-2.12.5-1.fc8
gtk2-2.12.5-1.fc8
rlove at falcon> rpm -q gtk2-devel
gtk2-devel-2.12.5-1.fc8
gtk2-devel-2.12.5-1.fc8

The gtk software is installed and at a version > 2.2.0.

The config.log tells me:

configure:2985: checking for GTK - version >= 2.2.0
configure:3072: gcc -o conftest -g -O2 -I/usr/include/gtk-2.0 
-I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0

-I/usr/lib/glib-2.0/include -I/usr/include/cairo     conftest.c  
-L/usr/lib -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgdk_pixbuf-2.0

-lglib-2.0   >&5

function 'exit'
/usr/gnat/libexec/gcc/i686-pc-linux-gnu/4.1.3/ld: cannot find -lcairo
collect2: ld returned 1 exit status

When I look for cairo, I clearly see it:

rlove at falcon> locate libcairo
/usr/lib/libcairo.so.2
/usr/lib/libcairo.so.2.11.7
/usr/lib64/libcairo.so
/usr/lib64/libcairo.so.2
/usr/lib64/libcairo.so.2.11.7
/usr/lib64/libcairojava-1.0.so
/usr/lib64/libcairojni-1.0.so
/usr/lib64/libcairomm-1.0.so.1
/usr/lib64/libcairomm-1.0.so.1.1.0

Now I'm also told to see the INSTALL file.  I don't see anything there 
applicable.  I don't have any prior version of gtkada installed, I have 
the required tools such as GNU Make, pango, atk etc.

Does anybody see what is wrong or what else I can try?  Why won't 
configure run successfully?

Thanks in advance for all pointers.
