I've posted descriptions on how to do this in the past, and so I won't repeat it here. Here's what I've done for small test codes: $ dllwrap --entry __cygwin_noncygwin_dll_entry@12 -o foo.dll \ --export-all --add-stdcall-alias [object files] [libraries needed] Then just use LoadLibrary to load the Cygwin DLL from your MSVC app. You cannot really *link* the DLL into MSVC since they're not compatible at the *link* level; it might work, and then again it might not. Perhaps you could ask Microsoft to make MSVC more compatible with Cygwin; they listen to the customers, right ;-) Note that there is a subtle and nasty bug in GCC that causes STDCALL functions to misbehave when the return type is float or double. It only affects STDCALL functions. Regards, Mumit - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request@cygnus.com" with one line of text: "help".
