Jignesh,
On which OS are you compiling Apache? If on UNIX, you can specify the flag
with ./configure, like:
./configure --prefix=<INSTALL_PATH> CFLAGS="-DDEBUGGING"
and then compile.
If on Windows, you have to add "-DDEBUGGING" for compiler flags in all the
.mak files.
The other way is to use "#define DEBUGGING" or "#define DEBUGGING 1" in the
file in which you want it to be enabled.
Regards,
Tejas Sanghavi.
