Hi,
It works now.!
I tried "-mwin32" in the makefile at the highiest level and I 
don't have any problems in building the gdb.

thanx for the suggestions

hello,
Thanks for the info.
According to the following link:
http://www.vas-gmbh.de/software/mpcbdm
for running the bdm,I have to use the Insight-GDB 5.0 version 
itself.

I could solve the undefined reference in libgui using -D_WIN32.
But the few other error still persists as fallows:

*****************************************************

make[1]: *** [gdb.exe] Error 1
make[1]: Leaving directory

make: *** [all-gdb] Error 2
******************************************************


I searched for the function "FreeConsole()" and could find it in 
the /cygwin/lib/w32api/  in the libkernel32.a.
The following was output after nm.exe:



*****************************************************

$ nm libkernel32.a |grep FreeConsole
00000000 T _FreeConsole@0
00000000 I __imp__FreeConsole@0

****************************************************

So I guess that the definition of the unreferenced function is 
present in the libkernel32.a.
I added the libkernel32.a to the final linking of gdb.exe.
But still the error persist , what could be the problem?
Am I using the right library or does the order of the linking 
matters?

Regards
Prasanna

Ah, ok. I see. Too bad: insight 5.0 is really, ummm, marginal.

Yes, you are correct: you need to link against kernel32.

It often does. Did you put it last in the list of libraries?
