Hi, I am using Sun OS 5.8 and we had to reinstall the OS on the machine due to certain problems. We installed gcc on top of that. After this re-installation, gcc doesn't work anymore. If I use the command # gcc test.c, nothing happens and it gets stuck forever. I have to kill the process. There are no error messages or warnings on the screen. It just gets stuck. It appears that gcc fails to find some OS specific libraries or something like that. Is there a way to find out if the problem is with the gcc installation or with the OS installation. Will reinstalling gcc help or should i re-install the OS ?. Thanks mallik
