problems with gtk+, and xlib

First off, I'm kind of curious as to what other people use... gtk+? xlib?

any suggestions? before I get too deep into one?

Secondly, I was first trying to make some sample code compile using Xlib, I got it to compile, but I was getting link errors...

So I tried to get some sample code working that used gtk+, I got it to compile finally, but I'm still getting similar link errors.....


Such as:
/tmp/ccIGk5Yw.o: In function `create_bbox':
/tmp/ccIGk5Yw.o(.text+0xd): undefined reference to `gtk_frame_new'
/tmp/ccIGk5Yw.o(.text+0x20): undefined reference to `gtk_hbutton_box_new'
/tmp/ccIGk5Yw.o(.text+0x2d): undefined reference to `gtk_vbutton_box_new'
/tmp/ccIGk5Yw.o(.text+0x42): undefined reference to `gtk_container_get_type'
/tmp/ccIGk5Yw.o(.text+0x50): undefined reference to `gtk_type_check_object_cast'
/tmp/ccIGk5Yw.o(.text+0x5b): undefined reference to `gtk_container_set_border_width'
/tmp/ccIGk5Yw.o(.text+0x6f): undefined reference to `gtk_container_get_type'
/tmp/ccIGk5Yw.o(.text+0x7d): undefined reference to `gtk_type_check_object_cast'
/tmp/ccIGk5Yw.o(.text+0x88): undefined reference to `gtk_container_add'
/tmp/ccIGk5Yw.o(.text+0x9c): undefined reference to `gtk_button_box_get_type'
/tmp/ccIGk5Yw.o(.text+0xaa): undefined reference to `gtk_type_check_object_cast'
/tmp/ccIGk5Yw.o(.text+0xb5): undefined reference to `gtk_button_box_set_layout'

These are only a few, but they are all similar to this, even the Xlib ones..... I don't know what this is telling me, can someone explain it? and give me some hints as to how I can fix the problem? I'm just trying to get SOMETHING that brings up a window so that I can learn and play with it from there....

Thanks much,

Hi!

Try this:
gcc mygtkprog.c -lgtk -lgdk -lglib -lm

(maybe you need still some more libraries)

Hi there!

i'm new in linux but i like it very much. Does anyone out there wanna give me a briefing on what exactly is Gtk?
and where can i find a good enviornment for compiling C++ programs. I mean, this gcc thing is really killing. I am using right now a Borland 3.1 compiler because i am working in DOS.




Thanks.

I had the same problem, took me a good time to figure out.

type gtk-config --libs --cflags<ENTER> in the console.
copy the output
type cc
paste the output

what you have here is a command lying in the console wich calls the compiler with all the info gtk+ needs.

this could look like this:
cc -I/usr/include -I/usr/local/include -L/usr/lib -L/usr/local/lib
-L/usr/lib/gtk -lgtk -lglib -gdk

(typed it from memory)

now add to the command line the name of your file(s) and the program name like you do usually (file.c -o program e.g.)

press <ENTER> and you are good to go!

However, pasting this into the command line all the time is a tedious thing to do. You could set up an alias to do this automatically:

alias cc='cc alltheflagsareputhere '

this does the trick, type it into ~/.bashrc

But rember, this doesn't work in a Makefile.

There is also supposed to be possible to type:
cc 'gtk-config --libs' 'gtk-config --cflags'
to accomplish the same thing, but it's never work with me.
