Greetings, I am developing a multi-threaded application (written in 'C') on Linux on the AMD x86-64 platform. I would like to know what compile and link options I should be specifying to ensure that the application builds properly. (We are using the posix thread model). The only thread related option info I can find in the AMD x86-64 Options section of the online manual is the -mthreads option, which is for "thread-safe exception handling on `Mingw32'", which is not applicable. Below is my gcc version info and some system info. gcc -v Reading specs from /auto_mnt/local/install/gcc-3.4.1/bin/../lib/gcc/x86_64-unknown-linux-gnu/3.4.1/specs Configured with: ./configure --prefix=/usr/local/install/gcc-3.4.1 --with-system-zlib Thread model: posix gcc version 3.4.1 uname -r -v -p -o 2.6.5-7.283-smp #1 SMP Wed Nov 29 16:55:53 UTC 2006 x86_64 GNU/Linux Your help is greatly appreciated, Frank Tufano
