I have installed Dev-c++ with Mingw64 on a winxp 64-bit machine. Now, when I try to compile my code, Dev-C++ returns the message "CPU you selected does not support x86-64instruction set". In "Project Options" of my project, the target CPU is set as "Pentium4". I have changed it to other types but no one is supports 64-bit instruction set. Has anybody experienced such problem before?
Thanks,
D.

Dev-C++ is not aware of any 64bit versions of GCC. You will have to manually add the compiler switches rather than use predefined dialog-box settings. There is a box for entering arbitrary settings.
Check the Compile Log text to ensure that what you think you are setting has been set, and that no conflicting options are set. Of course posting the compile log text would have been a good idea. You may say you have set an option, but there is nothing better that documentary evidence, and other settings that may be an issue can be checked for you.

The options that may be set are described at http://gcc.gnu.org/onlinedocs/gcc-4.4.1/gcc/i386-and-x86_002d64-Options.html#i386-and-x86_002d64-Options
It would shock me if Dev worked at all in that situation. It is very old, unmaintained,
and was built to support GCC-3.4...
