This forum is English only.
You probably need to add the library implementing __imp__pcre_free to the linker project settings.

Yes but I thought that the definition of pcre_free is in pcre.lib cause it is declared in pcre.h.
I linked it but it doesn't work, only for this function, the other function pcre_xxx don't seem to pose problems
?.? :(

If you want to statically link against the .a file, you must define PCRE_STATIC before including pcre.h, otherwise the pcre_malloc and pcre_free exported functions will be declared __declspec(dllimport), with hilarious results.

I didn't read the documentation, pcre is wellknown library, it is amazing that we have to do some stuff like that...

anyway

great thanks, I'll try that

If you wish to become a real Windows programmer, you will find out that reading the documentation is needed to use any slightly complex Windows Library shipped as an DLL because of import/export issues.
