How to add a default include path for GCC in Linux?
just a note: CPLUS_INCLUDE_PATH
and C_INCLUDE_PATH
are not the equivalent of LD_LIBRARY_PATH
.
LD_LIBRARY_PATH
serves the ld
(the dynamic linker at runtime) whereas the equivalent of the former two that serves your C/C++ compiler with the location of libraries is LIBRARY_PATH
.
Create an alias for gcc with your favorite includes.
alias mygcc='gcc -I /whatever/'
Try setting C_INCLUDE_PATH
(for C header files) or CPLUS_INCLUDE_PATH
(for C++ header files).
As Ciro mentioned, CPATH
will set the path for both C and C++ (and any other language).
More details in GCC's documentation.
