> I've never seen a version of GCC on Solaris x86 or Solaris SPARC that could build 64-bit binaries, so I've never tried it.
GCC compilers that were used for compiling 64-bit binaries: - GCC 3.4.6 for Sun Sparc / Solaris 10. - Download from http://www.sunfreeware.com/indexsparc10.html - (I think GCC that comes with Solaris 10 in /usr/sfw/bin can build 64-bit as well.) - GCC 3.4.3, that comes with Solaris 10 x86 OS installation, can build 64-bit. "If you need to do 64-bit compiles, you should use the gcc-3.4.3 that comes with Solaris 10 in /usr/sfw/bin." (See comments at http://www.sunfreeware.com/indexintel10.html for gcc-3.4.6-sol10-x86-local.gz) Note: Xerces-C 2.8 support 64-bit on Solaris x86 or Solaris SPARC. I have built successully.
