-I directory
In order to find include files the compiler driver arranges for the compilers to search a number of standard directories. You can add directories to the search path using the -I switch which is passed on to each of the language processors.
To set the directories searched for include files for a project:
To set the directories searched for include files for a particular file:
To tell the compiler to search the directories ../include and ../lib/include for included files when compiling file.c use the following:
hcl -I../include -I../lib/include file.c
You can speciify more than one include directory by separating each directory component with either a comma or semicolon, so the following command lines have the same effect as the one above.
hcl -I../include,../lib/include file.c hcl -I../include;../lib/include file.c
