[flext] Can't run Flext Template example (or any others) in Pd (OSX 10.6.3, Intel)

[Nicholas Mariette]

I tried several things, and finally, by using the _deployment configuration_ I was able to make the template example load in Pd (as a myext object).

The _development configuration_ doesn't work for me.

I definitely don't have any flext dylibs lying around, but I can see that the "symbol not found" error is looking for a dynamic version of a flext function, so I guess there is an Xcode setting somewhere that is still causing the development configuration to expect a dynamic library.

I tried searching the files within the .xcodeproj package, and found things in the text editor that don't show up in the xcode settings, but it's a bit hit and miss trying to edit project settings in a text editor.

So anyway, the template example now loads in Pd.  I quickly tried my adaptation of the henon example, but I get this error:
load_object: Symbol "henon_setup" not found
(at least it's not as bad as before).

It's a bit late here (Melbourne, AU) for me to bother trying to fix that for now, so I expect I can get it going tomorrow.
I'll also try the Template again from a fresh checkout from svn, just to confirm if development config is faulty for me.

thanks for your help!
Nick
