the problem with rtl.h and the make file

navderm · 12-22-2008, 03:12 AM

i have included rtl.h within <> signs.
and the Makefile has the code

hello.o: hello.c
gcc $(CFLAGS) hello.c

(this program was copied from one of the pdfs to learn real time controling and i got stuck so would need help please)

after this the rtl.mk was copied to the same folder

typing make -f rtl.mk hello.o doesn't help and i am not being able to create hello.o.

if i try to create it using normal gcc code it shows error as the code includes rtl.h header.

what should i do??

You can also use the -I and -L options to point to the directory where rtl.h resides (recommended).

If it's in the same subdir as the source, then use "" as in:

Code:

#include "rtl.h"

But, I doubt that's the case with that file.

Just a small nitpick with -I (upper case i) you will specify additional directories to search in when compiling (thus directories that contain files you need to include in your code; -L is used to specify additional directories to search in when linking ( so as to find libraries specified with -l (lower case L) to link your code against).
