Re: [Mysql-cocoa-users] I've worked it out

[John G. <jo...@jl...>]

Hi Serge, and mailing list,

I'm now ready for public humiliation - ie. I've worked it out and it was=20=

a STUPID error on my part.

The link error should have raised the alarm bells, but anyway, I FORGOT=20=

to add the SMySQL framework to my project!!!

Since my source file compiled, I guessed that it had found the framework=20=

and therfore knew exactly what to do, but I still had to add it to the=20=

project using Project->Add Framework.

So now I can get back to finding errors in my code logic.

JOhn

PS. Serge, I'm not sure if I have Autodoc installed on my system (it=20
isn't in /usr/local/bin) and this may be why the build stopped early and=20=

didn't copy the files over?
