Re^2: XS linking problem

Thanks a lot for the use objdump on the object file and for the explanation !

I saw that there is a ExtUtils::XSpp module but it use build.pl instead of make and I have no experience with this.

I will translate my cpp code in c

No need to stoop that low! Instead prefix the functions you want to have C linkage with `extern "C"`: `extern "C" void send_string (const wchar_t * str);` [download] If you are forward declaring the function in a header you don't need to provide the extern declaration in the definition. Now you can provide a C API and still have the power of C++ to go forth and conquer the world. Premature optimization is the root of all job security	[reply] [d/l] [select]
