I am trying to make PHP 4.31 and have mySQL 4.1 already installed and working with my old PHP version before I started this upgrade. When I do the make I get

ext/mysql/libmysql/my_lib.lo(.text+0x3d1): In function `my_dir':

make: *** [sapi/cli/php] Error 1

Any ideas?

Thanks much!

yeah man i am having the SAME problem. i posted on here too, but no luck just yet. i'll let you know what i find out, and you do the same ok?

good luck =)

I remember having a MySQL related PHP compile failure with MySQL 4.x. Turned out the cause of my problem was relying on PHP's built in MySQL support, so I included the dir to my actual MySQL version and it worked fine.
