Question
I was trying a PAPI code to attach itself to an already running code but on compilation it gives an error papi_test.h : no such file or directory

exit( 1 );
}
Even when compiling the file attach_target.c in the papi-5.3.0/src/ctests folder same error comes. I want to monitor an already running C code using PAPI and attch the counters to it.
Solution
You are missing the include PATH (and probably the library path too), compile with:
gcc -I/path/to/papi/include/dir -c <filename> -L/path/to/papi/libs -lpapi
Additionally, you might benefit from a Makefile. Here is very fine explanation in "How to write a simple Makefile" and presumably everything you need to start with make
