Hi Jim,
 With the solution given by you my problem solved. Thanks for ur
valuable suggestion. Really I am tired in overcoming this problem from
last 3 days.

 I placed -mno-cygwin in my makefile.mk and DLL is loading into
simulator without giving any trouble to me. But I am in doubt that ,
IDE I am suing is cygwin and supposed to use cygwin libraires, doesn't
it rises any trouble?
I'm not sure I understand the question. If you are using the 'user32' library then you are not building a Cygwin DLL, you are building a Windows DLL. I don't know of any limitation to a Cygwin application using a Windows DLL so I do not see an issue with using your DLL with an application that is using Cygwin.

If you are using a Cygwin application, what functionality are you using in User32 that is not available via the Cygwin API's?
Thanks,
nsp

I installed gcc 3.4.4 and bale to compile the sources properly using
makefiles. Problem I am facing is with DLL. When I tried to build DLL
it is giving eerror as

/cygdrive/c/cygwin/bin/ld: cannot find -luser32
collect2: ld returned 1 exit status
make: *** [prog] Error 1

If you want to use the w32api libs, I believe you have to pass the
"-mno-cygwin" option to the compiler so it builds a native Windows
application instead of a Cygwin application.

I searched all the mailing lists and found the answer to re install
W32app package. But I cross checked with my installed files and
folders and found that "libuser32.a" exists.

If I copy libs in w32api to C:\cygwin\lib, DLL build is completed
sucessfully. But facing problem with simulator. DLL is not loading
into simulator, Simulator got hanged. My simulator lies in different
PC ( XP/ Intel processor ). But I am able to build exe and test it
properly.

My system configuration:

OS : Microsoft Windows XP [Version 5.1.2600]
Processor : AMD Athlon
GCC : gcc version 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)

GCC configuration :

Reading specs from /cygdrive/c/cygwin/bin/../lib/gcc/i686-pc-cygwin/3.4.4/specs

Please help me in resolving this issue. Thanks in advance.
