Any sane C/C++ will not produce a binary with syntax errors in the source code.
My guess is that you had a package.txt with a different source file defined in it, so that source file and resulting shared lib didn't correspond, which explains the type of error on object instantiation in Pd.
Attached is the package.txt i just used for compiling your code.

Can the buildsystem build the extern without beeing a propper code on it? cause when I tried that I was expectting to get no file but a lot of errors so I could start mending my code!

Now I'm trying to compile an external "of my own" (not really mine, actually it's a ripoff of someother guy (a nicer one)). The thing is that I got it compiled but when I call it from pd (after putting the dylib on the extra folder) I can't get any instance!

I've written some silly externs in C following the tutorial on pd's site, and it was fairly easy with xcode, so I thougth that with flext could be similar. I'll try what you suggest, thanx for the advice!
