[flext] dlopen: Symbol not found

[Patrick Gampp]

Hi Thomas,
thank you very much for your answer.

I checked my linker flags in Xcode and I actually link to the static library libflext-pd_sd.a with -lflext-pd_sd. 

The flext-libraries were generated using your  flext.xcodeproj, which I checked out from https://svn.grrrr.org/ext/trunk/flext. I adapted the header search path to /bin/pdextended/src and built it. I didn't execute the make and install scripts via terminal.
Then I used the template.xcodeproj and built it with the given settings. Again i adjusted the header search path to /[location of flext]/source/.

I checked flext-pd_d.dylib, libflext-pd_sd.a, libflext-pd_td.a with GNU's nm and none of them contained the symbol __ZN18flext_obj_single_d8FinalizeEv.

Is there a setting in the flext.xcodeproj I have to adjust? What can be a solution to this error?

Thanks again,
Patrick
