After reading the above, I had a look hoping to find more (updated) information on this DLL business. Am I looking at the same links? The one for relocatable DLLs http://cygwin.com/building-reloc-dlls.txt is dated 1997, the one for helpful hints references Cygwin b17 http://cygwin.com/dll-hints.txt and the one for more information doesn't work at all at the moment http://www.cs.mu.oz.au/. I was told months ago on this list that use of dlltool was deprecated and no longer necessary at all, yet that is commonly invoked in the above references. As I recall, the latest dllhelpers does not even use dlltool? So I am confused. Although I have muddled my way through building DLLs with Cygwin, I cannot find the updated dox mentioned. Sorry, I simply don't understand DLL's well enough myself to submit anything... but I can say that dllhelpers did allow me to figure how to build DLLs using what I believe to be the most modern means of doing so with Cygwin/GCC.

Re: .dll.a, .dll files and other questions
Chris, thanks a lot! http://cygwin.com/cygwin-ug-net/dll.html seems to be indeed up-to-date! However, I strongly recommend to wipe or update related sections on http://cygwin.com/docs.html, just to avoid future confusions! Now that we straightened that one out, we can get to more interesting questions. I want to build an dll that uses Win32 global hooks. With the dll built under MS Visual Studio, I use dlltool on it to create a .dll.a from it and link it with my app under cygwin, everything works! When I build the dll directly under cygwin (what I really want to do, as I don't have VisualStudio!) using the instructions from http://cygwin.com/cygwin-ug-net/dll.html, and link it with my app, it does NOT work! Are there any restrictions under cygwin about the kinds of dlls that can be built?

Re: .dll.a, .dll files and other questions
Elfyn, those links on (http://cygwin.com/docs.html) describing how to build dlls seem to be utterly outdated. I was digging thru the doc trying to figure out how to build dlls myself and found much of conflicting information. can you point me to some info about to build dlls using state-of-the-art cygwin/gcc? in particular I'm interested in how to build dlls that use system wide win32 hooks. thx a lot.

Im not sure exactly what you mean. The gcc `-shared' option compiles shared objects (in this case dll's). If you mean something like `gcc -shared foo.o bar.o ...' then gcc expects object code.

Hi folks, Just had a couple of questions. Attempting to head off a problem at the pass... When using gcc -shared, what is default output (ie. what is expected from gcc - shared in order to read the .dlls/shared files) by Cygwin? Second question: If g++ -shared is used will the output .dll/shared files be loadable and/or useable by Win32 api?
