I’m writing this post in english in hope that more people find it useful…
Some times ago i really had bad problems installing the MySQL Gem 2.7 with Ruby 1.8.2 or 1.8.5 in conjunction with Rails 1.1.6 on Mac OS X 10.4
Compilation failed with:
Building native extensions. This could take a while…
mysql.c: In function ‘Init_mysql’:
mysql.c:2015: error: ‘ulong’ undeclared (first use in this function)
mysql.c:2015: error: (Each undeclared identifier is reported only once
mysql.c:2015: error: for each function it appears in.)
mysql.c:2015: error: parse error before numeric constant
mysql.c:2018: error: parse error before numeric constant
make: *** [mysql.o] Error 1

creating Makefile
The gem would then install with Successfully installed mysql-2.7. Creepy!!! But that damn thing just didn’t work.
After quite some googling i found this one:
Running Rails on OS X with MySQL 5.0.24
It’s all about puting a little
#ifndef ulong
#define ulong unsigned long
#endif
somewhere in “/usr/include/stdlib.h”.
This tipp is still necessary for MySQL 5.0.24+. Thanks again mate!!
But here the trouble starts….
I put the define in a nice little conditional just in case but bah… It would come down to hunt me…
For my project DailyFratze.de i also need RMagick. Again, the gem (1.14.1, 1.14.0 and 1.13) failed to compile but didn’t tell (on runtime it said “require “RMagick” LoadError: No such file to load — RMagick.so” … ) and installation from source did fail as well with:
setup.rb:655:in `command': system("make") failed (RuntimeError)

make: *** [all] Error 1Damn! After banging my head against the walls, reinstalling ImageMagick and all it’s depencies either direct from source, via i-installer and finally as mentioned here i took a break, visited some porn sites and stuff like that and though, hmm… stdlib.h….
I removed the little define and bam! It’s that easy, RMagick compiles just fine…
From the forums i found i guess other people with the same error message may have the same problem as i had…
I really wish installing a ruby on rails environment would be a less pain in the ass…. somewhere near as easy as developing with rails.
