Creation of a shared module (gcc -shared) , undefined references


Hi

I try to port on CYGWIN an open source which runs correctly on Linux.
In this open source, a shared module (linked with option -shared) is created and after it's loaded by the main program with lt_dlopen() function.


On CYGWIN, I have a problem when I create the module (gcc option -shared). I have always some undefined references to functions which belongs to the main program. On Linux it's not a problem, there are no errors.
I try to add the option -Wl,-allow-shlib-undefined. I have always the problem.


I don't know what to do. Are there other options to add to the gcc command ?I tried several..or do I have to modify the source code of the module?
I'm not very familiar with shared modules.


Thanks for your help
Best regards
Martine
