I have tried to compile gdb 5.1 (20010910) on Solaris 8 (using gcc 3.0). It successfully compiles, it works on 32 bit binaries, but when I try to debug a 64 bit binary it is not able to set a breakpoint in main. Has anyone made gdb 5.1 work on Solaris 8 on 64 bit binaries? Eric Aversa eaversa@omnesys.com Omnesys Technologies, Inc.
