Re: Makefile for GTK2 programs?

 What CFLAGS and LIBS I should use in Makefiles?
 I installed GTK2 to home directory, and thus I won't use lddconfig.
 My programs should take all from ~/gtk2/, and nothing from
 /usr/include/gtk-1.2/ and nothing gtk-related from /usr/lib/.
 
 GTK2 does not have gtk-config program. It made things easier
 in gtk1.2:
 
   CC=gcc -O2 -Wall
   CFLAGS = `gtk-config --cflags`
   LIBS= `gtk-config --libs` -lm -ljpeg -lpng
 
 Is there away to get all CFLAGS and LIBS by checking the pkgconfig file?
   ~/gtk2/lib/pkgconfig/gtk+-2.0.pc

CFLAGS=`PKG_CONFIG_PATH=~/gtk2/lib/pkgconfig:$PKG_CONFIG_PATH pkg-config 
--cflags gtk+-2.0`
LIBS=`PKG_CONFIG_PATH=~/gtk2/lib/pkgconfig:$PKG_CONFIG_PATH pkg-config --libs 
gtk+-2.0`

(you might have to replace ~ by the real path)

hope this helps,
regards,
Jean

 
 I have now the following in Makefile. Very messy. It does not work;
 I get errors: undefined reference to `gtk_text_view_new' and the like.
 
   CC=gcc -O2 -Wall
   CFLAGS= -I/home/juhana/gtk2/include/glib-2.0 
 -I/home/juhana/gtk2/include/gtk-2.0 -I/home/juhana/gtk2/lib/glib-2.0/include 
 -I/home/juhana/gtk2/include/cairo -I/home/juhana/gtk2/include/pango-1.0 
 -I/home/juhana/gtk2/lib/gtk-2.0/include -I/home/juhana/gtk2/include/atk-1.0
   LIBS= -L/home/juhana/gtk2/lib -lgtk -lgdk -rdynamic -lgmodule -lglib -ldl 
 -lXi -lXext -lX11 -lm -ljpeg -lpng
 
   O_ESPBROWSER=mylib/filesdirs.o mylib/buffer.o mylib/image.o 
 mylib/gsl_taus.o mylib/clock.o mylib/mmapfile.o mylib/sprint.o mylib/arrays.o 
 espbrowser.o
 
   all:: espbrowser
 
   espbrowser: $(O_ESPBROWSER)
   $(CC) $(CFLAGS) -o espbrowser $(O_ESPBROWSER) $(LIBS)
 
 
 I use this include command in the C code:
   #include /home/juhana/gtk2/include/gtk-2.0/gtk/gtk.h
 I'm afraid it won't help because gtk.h uses
   #include gdk/gdk.h
 which may be /usr/include/gtk-1.2/gdk/gdk.h.
 
 
 How the linked ld works? My programs are simple. Perhaps I could
 write a script to compile and link everything explicitly. But this
 include file business worries me still.
 
 This is so frustating. I will return to GTK 1.2 soon.
 First Ubuntu failed to install GTK2, and now this!
 
 I could start writing my programs under demos/gtk-demo/ and compile
 the demo. But then I don't understand how to add my mylib/mmapfile.o
 etc. files to the configure system. :-(
 
 Help needed.

If you are using ubuntu it will already have gtk2 installed, as it
depends on it.  No distribution has used gtk+-1.2 as the basis of its
desktop environment for about 8 to 10 years.

You probably just need to install the ubuntu development package
containing the gtk2 headers.

When does the error happen? If it is at run time, you may want to add
-Wl,-R/home/juhana/gtk2/lib to LIBS...

Cheers,

apt-get install libgtk2.0-dev? And maybe libglib2.0-dev?
