PHP compile - with MySQL - under 64-bit Solaris?

Has anybody build PHP from scratch on 64-bit Solaris?

Am running into trouble - in the confguration step - in portion related to MySQL setup. ld is complaining about wrong ELF flags...

Here are some relevant details from the config.log:
--------------------------------------------------------

seems clear to be an error wtih ld - can anyone point mein the right direction? thanks in advance. Lou

gcc 3.3.2 is pretty old - I don't know that it can handle creating 64 bit binaries.

The issue though seems to be that MySQL was compiled for 64 bits but you're compiling with 32 bits. I'd look at the gcc 3.3.2 manual to see how to turn on 64 bit compiling or recompile MySQL for 32 bits.
