-----Original Message----- From: Anik Pal [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 05, 2008 8:17 PM To: '[EMAIL PROTECTED]' Subject: RE: RE: undefined reference to `_msgDebug' in GCC Phil, Thanks for the info you provided. Im not conversant with GCC. I remove the path for regular library like libm.a, and all the paths specified in posix , now my linker option is as follows -L/cygdrive/f/geolog6.6.1/lib -lcgg -llicence -llogs_dll -lPGILc_dll -lPGILcTool_dll -lcgs -lgeolog6 -L/cygdrive/D/cygwin/lib/mingw -lmsvcrt -Bstatic -lm But Im not sure how to remove the dependency on libmsvcrt.a (that comes with mingw lib in cygwin). What is the equivalent lib in cygwin/lib? Moreover I followed the solution stated in the following url to get rid of linking undefined reference symbol __chkstk http://eegeerg.blogspot.com/2008_01_01_archive.html#4158852069709002699 which actually states to copy chkstk.OBJ from MSVC/lib and rename to chkstk.o and link with this. Now linking error goes but when try to execute this exe, it doesnt gives any error message but terminate unexpectedly.

Cygwin is a POSIX environment, so use POSIX pathnames (I.e. "/cygdrive/f/" instead of "F:/") Second, you're linking with cygwin AND msvcrt and potentially also mixing cygwin and mingw libraries. Don't do that. The cygwin, msvcrt and mingw are fundamentally incompatible. [Although it is possible under very specific circumstances to mix cygwin and msvcrt, it requires knowledge of the internals of both libraries, and if you had that knowledge, you wouldn't have posted your question, so the advice stands] Make your mind up whether you want to write a POSIX program or a Windows program and stick to your decision. Third, let the compiler choose the C runtime library. You don't specify -lcygwin, nor the path to the standard library locations, so the only -L you need is "-L/cygdrive/f/geolog6.6.1/lib" Fourth, libm is integral to cygwin1.dll, so you don't need -lm. The math library supplied with cygwin is only a stub to support makefiles such as yours that assume it's necessary.
