[flext] error while compiling parch PD

[alessandro mason]

I've tried to ling dll library, to make the suggested corrections, but
nothing changes.
So, i've implemented the external under Linux/Debian with codeblocks and I
compile the file with no errors.
I've changed the extention of the created library from .so to .pd_linux and
i've load the external in PD. But the PD console shows this error:
./libplus.pd_linux: ./libplus.pd_linux: undefined symbol:
_ZN17flext_base_single4InitEv

What can I do?

PS. Sorry for my English :-D
