have installed and am using the GNU based tools from the Sunfreeware site to compile PHP. I already have Apache, MySQL, and Oracle compiled and working properly. Below is my configure string for my PHP build:

./configure --prefix=/usr/local/php5 \

I have ld, make, and various tools linked to /usr/local/bin/<toolname>. The configure string completes with no issue and the make runs for about 30 minutes before it stops with the following warnings/errors:

There are many, many more "undefined reference" messages all mysql related.

Here is my environment and crle output:

crle output

Any ideas as to how I can get around the MySQL errors, etc. would be appreciated.

are you running mysqli ? if not don't compile php with it.

Use blastwave. I was having trouble with the SunFreeware site, especially one of the required packages for PHP wasn't at the appropriate version on SFW. I removed all the SFW packages and went to http://www.blastwave.org. It does package dependencies just like a Linux distro and it was quite seamless when I did the installation on one of our Virtual Solaris machines.
