Occi problems while compiling in linux

Question

hi guys
i've been trying to compile the occi programming examples but i always get the following error.

i tried following the instructions in this forum about installing gcc 2.95.3. since i was using 3.2.2. I installed gcc ok but i still get the same problem. i think its something to do with the shared libraries or include paths but i cannt figure how. any help will be appreciated. am running redhat 9.0 and oracle 9 rs 2.
regards solomon

Hi all.
I've same problems. I try to download and install 2.95.3 from http://gcc.gnu.org/releases.html (since there isn't any refercence to 2.96!) but the problems persist again.
So I tryed to analyze the library with 'nm -CD $ORACLE_HOME/lib/libocci' and I saw there isn't no exported symbols, then I rebuild it with the object files found in $ORACLE_HOME/lib/libocci9.a' and now the library exports all function oracle::... but when I try to recompile the example demo/occidml I get the error
/opt/gcc2.95/bin/g++ -o occidml -I. I/opt/oracle/oracle92/rdbms/public -L/opt/oracle/oracle92/lib -L/opta/oracle/oracle92/rdbms/lib -locci -lclntsh 'cat $ORACLE_HOMElib/sysliblist' occidml.cpp
/opt/oracle/oracle92/lib/libocci.so: undefined reference to '__ctype-toupper'
collect2: ld returned 1 exit status
WHERE I CAN DOWNLOAD THE gcc2.96????
