Hi Helge I find something interseting in your reply and i can feel that with this approach i can make my code work. But i need to know how to make use of that personality function for my code. for example my code test.c is in root folder, then where should i have your code?inside my test.c or in a separate file? My test.c is compiled using "gcc -o test.o test.c" Kindly guide me. -- View this message in context: http://www.nabble.com/GCC-Compilation-problem-in-HP-LINUX-server-tp24806245p24820537.html Sent from the gcc - Help mailing list archive at Nabble.com.
