Finally, I found a nice solution for the RoR 2.2 MySQL problem. The initial problem was that the MySQL library isn’t bundled with RoR anymore, and you need to install it as a gem. No big deal at first, but we Leopard users are “plagued” with the fact that Apple has somewhat of an exotic installation method of web programming.
The stock MySQL and Apache are both 64bit, but the Ruby interpreter is 32 bit. That’s why you can’t use the 32 or 64 bit MySQL library gem. I found a lot of “idea’s” on the net, but none of them helped out, or I didn’t think they where good enough.
One of them was to run a second MySQL instance on 32bit. A lot of users solved that way but I found it just stupid running 2 MySQL instances. So then it struck me, why not recompiling the stock MySQL as a universal build that supports both 32 and 64 bit?
So I did. I downloaded the source from the MySQL website and compiled it like this:
MACOSX_DEPLOYMENT_TARGET=10.5 \ CFLAGS='-O3 -fno-common -arch i386 -arch x86_64' \ LDFLAGS='-O3 -arch i386 -arch x86_64' \ CXXFLAGS='-O3 -fno-common -arch i386 -arch x86_64' \ ./configure \ '--disable-dependency-tracking' \ '--prefix=/usr/local/mysql' \ '--localstatedir=/usr/local/mysql/data' \ '--libexecdir=/usr/local/mysql/bin' \ '--with-comment=MySQL Community Server (GPL)' \ '--enable-thread-safe-client' \ '--enable-local-infile' \ '--enable-shared' \ '--with-zlib-dir=bundled' \ '--with-big-tables' \ --with-readline \ '--without-docs' \ '--with-plugins=myisam,innobase'
And my problem was solved. I had one MySQL instance running, and I finally could use RoR 2.2. Now the only problem remaining is getting PHP to run properly.
