OK, that's clear.


>I have written my main function in c which should use this dll. 


So you mean you've created a main.c with main() and main() will call into the
windows DLL via some function exported from the DLL.  Is that right?


>I would like to compile the code using gcc. 


I'm assuming main.c linking against the .LIB created by VC++ for your DLL,
right?


>I have tried to use the export dll concept explained in cygwin user guide but that is not working for my case and generating ld error.


OK, but we don't know what main.c looks like, what function in the windows
DLL you're calling, how it was exported (as a C or C++ function), how you 
compiled and linked all this, and what the error was.
