[Mysql-cocoa-users] Re: Requirement for libmysqlclient....

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

I'm afraid there is a missunderstanding...

The SMySQL_fully_embeded version of the framework does not need=20
libmysqlclient around (it contains the code of it). STILL it is only=20
able to connect to an (existing and runing) MySQL DB server.

In other word, this is not (yet) a version of the framework which=20
contains the DB, it is only able to be client of a DB server. This=20
version will hopefully come (soon ?), but is not existing so far.

To put it in other words:
If you want to use MySQL using the SMySQL framework, you need both:
1. the SMySQL_fully_embeded version of the framework (in your=20
application bundle)
2. a running MySQL server (either on same computer or accross network)


Was that your question?

Serge.
