My school Red Hat system has gcc 3.2 as well as 3.4 installed on it. By default, all programs make use of 3.4. I am trying to compile a program that should work with 3.2 but not with 3.4. However, I do not know how to force the program to compile using 3.2 instead of the default 3.4. I use: ./configure --prefix=/path Could someone please help me with this ? I assume we can set a certain flag to specify the old gcc version but dont know which. Also, how do we check all the gcc versions available ? Thank you Vinayak. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
