As the title. I have a program must be compiled only in DEBUG mode. (testing purpose) So I want to prevent compilation in RELEASE mode by this way.

Place anywhere:
#ifndef DEBUG
#error Only Debug builds are supported
#endif

If you simply want to report an error:
#ifdef RELEASE
#error Release mode not allowed
#endif
will work with most compilers.

You can use a error directive for that. The following code will throw an error at compile time if DEBUG is not defined:
#ifndef DEBUG
#error This is an error message
#endif

You didn't specify and `#pragma` statements. Your preprocessor directives are valid and portable.

Sorry, I mix pragma and error while typing. Corrected in answer.

C provide a #error statement, and most compilers add a #warning statement. It is recommended to quote the message.
