gtk programming problems

[solaris235]

Hi all, I'm trying to do some programming with GTK.
I have everything installed libs and includes and GTK applications run fine.
But trying to compile this simple program...

#include <gtk/gtk.h>

int main( int argc, char *argv[])
{
GtkWidget *window;

gtk_init(&argc, &argv);

window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_widget_show(window);

gtk_main();

return 0;
}

I get a whole bunch of errors.

make: *** [Test.o] Error 1



There were some more but I discovered some declarations in various include files that were commented out. I removed the comments and some of those errors were gone.
I'm thinking I have the wrong development package. I'm using the package that installed with Ubuntu 10.10

I've also compared header files with these packages
gtk+-2.22.0
pango-1.28.3
glib-2.26.0
I can't find any differences
Anybody have any ideas ??????

Thanks, but I've been there and done that.
The compiler finds all the files it's looking for.
The linker finds all the files it's looking for.
There are definite problems with the set of development files that I have.
I've tried Eclipse, Netbeans, Codelite, and direct from the command line with the files explicitly entered and with the pkg-config with the same result every time.
Even compiling the assembler version of the same code yields the same results.
I'm getting quite frustrated.

Let's see...

0. You say you installed GTK+... From where? How? You know the best way to do it is by installing the libgtk2.0-dev package... This may seem obvious, but sometimes people that use KDE fear that doing that will install the whole GNOME suite (which won't happen) and try installing GTK+ from source.

1. You're using a really weird compiling command. The way to compile GTK+ applications is the following:

# Using gcc... see below
gcc -o my_app my_app.c -Wall -Wextra -pedantic $(pkg-config --cflags --libs gtk+-2.0)

I see you're using a Makefile. Please, post it... the bug is surely there.

2. Use gcc and g++ properly. Your code, despite having the *.cpp extension is C, not C++... and GTK+ is C (gtkmm is C++). Ok, this may sound a bit snobbish or whatever, but it's always better to use the corresponding compiler... or you may get some quirks. It wouldn't be the first time we come across some error produced by trying to compile C code with g++ (no, C++ isn't a strict superset of C... and moreover, it changes some fundamental parts of C semantics). I compiled your code using g++ and I got no errors. Also, if you're going for C++ GTK+ programming, I highly recommend you to use gtkmm instead... gtkmm will make use of all OOP features C++ has and make everything much easier for you.

[solaris235]

Hey nvteighen, thanks for the response and the things to try.

0. I'm using Ubuntu 10.10 with the gnome desktop, GTK+ is install with the system. I did install the libgtk2.0-dev package through the package manager.

1.The compile command I used is generated by Eclipse, I also tried yours and I get the same errors only worded for C instead of C++

Here's the Eclipse generated make file

2. I know that the code should compile and run because everyone else can get it to work but me. I've tried gcc and g++. Ultimately I want to do my coding in assembler which should work fine using gcc and gtk. I'm just trying to get gtk development package working.

I guess I can always just use X11 directly. (but I don't wanna)

Any more idea's.... anyone....

[nvteighen]

1.The compile command I used is generated by Eclipse, I also tried yours and I get the same errors only worded for C instead of C++

Wait a minute. Did you use my command on Eclipse?

Ugh... I see I didn't mention you to use it on a Terminal, rather than on the IDE. I haven't ever used Eclipse, so I don't know how it is supposed to work; what I want you to check is whether it is an IDE-related thing or something else is preventing the code to compile (I'm able to compile it and I can assure you your code is correct except for a detail that's irrelevant now).

So, please, enter the compile command I posted before into a Terminal.

[solaris235]

I did run your command line in a terminal. Like I said earlier I've tried this with 3 different IDE's as well as the terminal.

I've since done a full reinstall of glib, pango, atk, gtk+ as directed on the GTK+ website. Everything went perfectly.
BUT...
My error count has dropped to 25 errors
So I'm making progress...
But it still doesn't work!!!!! arg!!!
I must still be missing an include file or there is a declare statement missing somewhere.

Your code compiles fine for for me on 10.10 Maverick, written as a C file. The only additions needed were the appropriate pkg-config commands to set CFLAGS and LDFLAGS properly. As with the following makefile:

CC=gcc
CFLAGS=-Wall -O0 -g3
CFLAGS+=$(shell  pkg-config --cflags gtk+-2.0)
LDFLAGS+=$(shell pkg-config --libs   gtk+-2.0)

hello_gtk1: hello_gtk1.c
        $(CC) $(CFLAGS) $(LDFLAGS) -o hello_gtk1 hello_gtk1.c

What version gcc are you using?

$ gcc --version
gcc-4.4.real (Ubuntu/Linaro 4.4.4-14ubuntu5) 4.4.5

Here's how the make expanded (without CODE blocking so the line wraps):

gcc -Wall -O0 -g3 -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 -pthread -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgio-2.0 -lpangoft2-1.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lm -lcairo -lpng12 -lpango-1.0 -lfreetype -lfontconfig -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lrt -lglib-2.0 -o hello_gtk1 hello_gtk1.c

Hey gmargo, thanks for the input...
I'm using...

gcc (Ubuntu/Linaro 4.4.4-14ubuntu5) 4.4.5
Copyright (C) 2010 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

I've used pkg-config in every way that it can be used,
I tried your makefile,
I tried your gcc command line,
I still get the same errors.


I know the C code it good. (everyone else can get it to compile and run)
I know that gtk+ runs on my Maverick system. (Other apps that use gtk+ work fine)
I know that gcc works fine.(I can compile and run other programs that don't use gtk)
I know that g++ works fine.(for the same reason as gcc works)

That leaves my development package as the problem
Here are the libgtk2.0 packages that I have installed

libgtk2.0-0
libgtk2.0-doc
libgtk2.0-0-dbg
libgtk2.0-common
libgtk2.0-bin
libgtk2.0-dev
libgtk2.0-cil

installed versions of everything are 2.22.0-0ubuntu1 except libgtk2.0-cil ver: 2.10.12-1
in case it matters I have Gimp Version 2.6.11-1~getdeb1~maverick installed as well.

am I missing something or should I remove something ??????

/usr/include/glib-2.0/glibconfig.h:38: note: this is the location of the previous definition

I find this error message very interesting.

I do not have this file: /usr/include/glib-2.0/glibconfig.h. "locate glibconfig.h" on my system shows it at this path: /usr/lib/glib-2.0/include/glibconfig.h, and it does not contain the G_GNUC_EXTENSION definition. It is from the libglib2.0-dev package.

So where did that file come from? Try "dpkg -S /usr/include/glib-2.0/glibconfig.h". And take a look at it. Is it a symbolic link? Or a misnamed copy of something else?
