Thread: Problem with Makefile

Hi Everyone,
I am new to c++ programming I got a full code in c++ with a Makefile. In Makefile i have to use header files which are in a sub directory in the directory I am working. Like I am working in PEM directory and src directory is in PEM and I have header files in src. So to include this src directory in makefile i am using the command
CPPFLAGS = -I../src
now if i compile makefile then it gives me an error like
IoSimple.h: No such file or directory
but this header file is in src i ahve checked it by listing files.
Can anybody help me i think so i am not properly mentioning the path to include the src directory???

Two dots goes up a directory. This would make src a sibling directory to where you are, rather than a subdirectory.

Thanks for your reply so what you suggest what should I used now rather than above mentioned statement??
