Another question:
I need to run C/C++ programs using CRSP for my research. CRSP related
stuff is located at /opt/crsp/. Specifically, I need to include a bunch of
header files (.h) located at /opt/crsp/include/ in my C/C++ programs, and
I want them to be able to include that path by default, i.e., without
having to specify the absolute path in each #include.
I tried to change PATH but it didn't work. Is there anything like
INCLUDEPATH? Thanks a lot.

Thanks. But the problem is, using -I, I can only save by writing
#include "crsp.h" instead of #include "/opt/crsp/include/crsp.h".
But "crsp.h" itself has a bunch of other #include "crsp_xyb.h".
What shall I do?
