Re: [pygccxml-development] Compilation problem

[Vincent F. <vin...@gm...>]

I tried to comment all the virutal method definitions in my generated .cpp file.
If I understand what was said on your link, the linker makes dynamic
links for virtual functions which are not redefined in the same file
while compiling which causes errors on runtime if it doesn't find
them, just like in my case.

But without any virtual function left, it should work.

I compiled again and still have the same error when importing the module...
