[Mysql-cocoa-users] MySQL on MacOS X

[Serge C. <co...@em...>]

Hi Robert,

I think it's really the time to go on the mailing list of mysql-cocoa...
I've not at all tested the framework (nor NySQL) on Jaguar, but some=20
people on the list did. I'm sure they would answer you better than I =
can.

What I can tell you is no more than that is in the doc on the project=20
web page (http://mysql-cocoa.sf.net).

There is also a couple of resources one can use:
- http://www.entropy.ch/software/macosx/welcome.html (good one, get=20
binary, and some explanation to compile yourself -if still the same-)
- http://developer.apple.com/internet/macosx/osdb.html (a very=20
comprehensive guide to MySQL installation on OS X... from Apple, that=20
should make a standard at some point)

and I'm sure you can still find some more on google.

By now I'm wondering if what your question is, is how to get libmysqld ?=20=

(the embedded server as they call it at MySQL)?
The guidelines from the resources I pointed you to should be enough. Be=20=

just careful to use mysql4 (libmysqld does not exist in previous=20
versions).

If you have specific problems when building the library (which is not=20
solved by these resources), I'll be happy to provide more help.

Serge.

PS: If you want to use libmysqld, you should be able to use the=20
framework for nearly everything, except starting the server thread (and=20=

killing it), with very little modifications (mostly, modification to the=20=

target, linking it to the static libmysqld instead of the sources of=20
libmysqlclient). In this case be carefull to add -fno-common during the=20=

compilation of the library, and add libz to the library to link the=20
framework with (I'm afraid of being a bit criptic, but you should=20
decipher it while starting "playing" with installation of mysql and the=20=

framework).
