Hi all,
I've recently started using the cygwin GCC implementation and I'm
having problems trying to create a Win32 DLL. I created a DLL and
exported a single function using __declspec(dllexport). My source
file is called cimp.cc and has only the function definition in it.
I tried executing the following (after compiling using 'g++ -c
cimpl.cc'):
dlltool -l cimpl.lib cimpl.obj
ld -Map cimpl.map -e 0 -E -o cimpl.dll cimpl.lib
The problem is that although the .lib file appears to have my
(decorated) function name in it, the generated .dll file does not.
I'm not really that clear on the full abilities of the dlltool and ld
tools, so I'm probably using them wrong. Do I even need to use ld?
By it's name dlltool sounds like it ought to do th job!
Also, can you tell me if I specifying the entry point correctly (using
'-e 0')? If I don't use this, dlltool seems to think that I want to
build a .exe file and subsequently fails looking for WinMain. Is
using a value of zero going to work (I have not DllMain specified in
my code)?
Best regards,
