Thanks. I found that on Solaris 11 the 64 bit libs are generated under /usr/gnu/lib/64 when gcc was configured with --prefix= /usr/gnu. Everything works on Solaris 11. However, I am facing problems on Solaris 10 as it seems there are no 64-bit libs generated there. I will ask another question if I can't seem to find a way.
Thanks so much for helping out on this.
