Not surprising - the import library is specific to the compiler
- in fact VC5 chokes on VC6's import libraries.
I'm not exactly sure how you would begin to export dll symbols
for gcc under cygwin.
One possible option is to use the dumpbin
utility from VC to find out the export functions in the DLL and
then use LoadLibrary etc. to manually load the DLL and find
the function addresses etc. to manipulate it.
Cheers,
Eliot

Hello List:
I'm building a program and trying to link against a vendor supplied .dll
using their .lib file. The code in question has successfully been built
under VC. I'm now attempting to build under cygwin.
This is supposed to be a Win32 console application.
Using this command:
gcc -Wall -omyapp.exe mysource.c c:/universe/lib/universe.lib
This results in myapp.exe being built.
Then I run myapp, and get a Win GUI message box:
"The procedure entry point could not be located in the dynamic link
library universe.dll"
I'm thinking either I gave incorrect arguments to gcc or that I have
some installation issue with the dll. The absence of any procedure name
in the message box makes me suspect arguments for some reason.
Anyone have any experience with this that could shed some light?
Thanx
Charles
