Can not build a simple program

rlp1938 · **Joined:** Thu Oct 13, 2011 5:50 pm **Posts:** 3

Here is my makefile:
all:
gcc -Wall $(pkg-config --cflags gtk+-2.0) -o statusbar.o -c statusbar.c
gcc -Wall $(pkg-config --libs gtk+-2.0) -o statusbar -c statusbar.o

Here is the error:
gcc -Wall -o statusbar.o -c statusbar.c
statusbar.c:2: fatal error: gtk/gtk.h: No such file or directory
compilation terminated.
make: *** [all] Error 1

#locate gtk.h
/usr/include/gtk-2.0/gtk/gtk.h

#pkg-config --cflags gtk+-2.0
-pthread -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/pango-1.0 -I/usr/include/gio-unix-2.0/ -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libpng12

The #includes from the program:
#include <stdlib.h>
#include <gtk/gtk.h>
#include <glib.h>

I must be missing something.

Hello and welcome to the GTK+ forums.

I don't think make understands $() notation. You should probably use backticks or $(shell ) notation. Your example code should look somewhat like this:

Code:

all:
   gcc -Wall $(shell pkg-config --cflags gtk+-2.0) -o statusbar.o -c statusbar.c
   gcc -Wall $(shell pkg-config --libs gtk+-2.0) -o statusbar statusbar.o

Cheers,
Tadej

You are right. Thank you!

Your makefile lines work and so do backticks.

Thanks,

Code:

CC=gcc
CCFLAGS=-Wall `pkg-config --cflags --libs gtk+-2.0`

all:
    $(CC) $(CCFLAGS) -o statusbar.o -c statusbar.c
    $(CC) $(CCFLAGS) -o statusbar statusbar.o

or for all cases in life

Code:

CC=gcc
CCFLAGS=-Wall `pkg-config --cflags --libs gtk+-2.0`
PROGNAME=statusbar
SOURCES=statusbar.c

OBJECTS=$(SOURCES:.c=.o)

$(PROGNAME): $(OBJECTS)
    $(CC) $(CCFLAGS) -o $@ $^

$(OBJECTS): $(SOURCES)
    $(CC) $(CCFLAGS) -c $^

clean:
    rm -f $(OBJECTS) $(PROGNAME)
