Amit, Thanks!!! Goof on my part.... That worked (along with c++) I also placed: LIBRARY_PATH="~/gcc/usr/local/lib/ environment variable in my .kshrc file so that I don't have to use the -L. Now I have to go and get boost installed.... Thanks again! -----Original Message----- From: Amit Choudhary [mailto:amit2030@xxxxxxxxx] Sent: Wednesday, September 27, 2006 12:41 PM To: Ferng, Andrew D; gcc-help@xxxxxxxxxxx Subject: RE: Help with gcc installation on AIX 5.3 Unless I am mistaken, you should be using g++.
