Hi There, please go through the followings for the problem:
1) I want to create a 64 bit DLL using Cygwin in Windows Serever 2003 64 bit platform. 2) I am using Cygwin to run the make file 3) In the make file I have a macro “CFLAGS” where gave the option “-m64” in the make file for 64 bit build 4) But when I use this option I am getting an error like: $ make -f makefile_64 g++ -c -DWIN64 -D"__int64=long long" -trigraphs -I../include -IC:/Progra~1/Java/jdk1.5.0_10/include -IC:/Progra~1/Java/jdk1.5.0_10/include/win32 -mno-cygwin -m64 Abc.C -o Abc.o Abc.C:1: sorry, unimplemented: 64-bit mode not compiled in make: *** [Abc.o] Error 1 5) The main thing is that I don’t know exactly what should be the option we have to give under cygwin for building a 64 bit DLL (though I have used “-m64” option), but in Linux if you use this option, you’ll get the 64 bit .SO file!!! i tried alot but tillnow didn't get the solution. Please suggest me some alternative options if anybody have. Thanks in advance!
