I have a Windows LIB/DLL that I need to link my GCC program with. I have
followed all the instructions I could find: using pexports to create .def
file from the .dll and then using dlltool to create a .a library file from
the .def file. I've dumped the symbols from the .a and noticed each function
is appeded with an underscore (_). Note that a dump of the DLL does not have
underscores prefixed to the function names. Also, the .def doesn't have any
underscores prefixed to the function names. I have been completely unable to
link my program when compiled as C++ getting the "undefined reference to"
error for each function in the DLL, but I am able to compile and link as C
code. Any suggestions? Thanks for any help.
