building gcc-4.4 with graphite

[Olivier Marsden]

Hello,
I'm trying to build gcc-4.4 with graphite support in order to test loop 
optimizations.
I can build gcc successfully without graphite, but if I add the cloog 
and ppl flags,
I get an error during make, indicating that libcloog.so.0 cannot be found.
Libcloog & ppl are correctly built, and the library files are located 
where I want.
The configure command used is the following:

./configure --with-cloog=/opt/cloog --with-ppl=/opt/ppl 
-with-gmp=/usr/local --enable-languages=c,c++,fortran

the error message obtained is as follows:

/home/marsden/sources/gcc_build_graphite/./gcc/xgcc 
-B/home/marsden/sources/gcc_build_graphite/./gcc/ 
-B/home/marsden/sources/gcc_final/x86_64-unknown-linux-gnu/bin/ 
-B/home/marsden/sources/gcc_final/x86_64-unknown-linux-gnu/lib/ -isystem 
/home/marsden/sources/gcc_final/x86_64-unknown-linux-gnu/include 
-isystem 
/home/marsden/sources/gcc_final/x86_64-unknown-linux-gnu/sys-include 
-dumpspecs > tmp-specs
/home/marsden/sources/gcc_build_graphite/./gcc/xgcc: error while loading 
shared libraries: libcloog.so.0: cannot open shared object file: No such 
file or directory



This is on rhel5.2 x86-64.

Can anyone tell me what is happening?
Many thanks
