GTK programming on Ubuntu5.10

[vk99]

Hi,

I've worked on C,C++,Java(Swing and JDBC) on microsoft windows as a part of my university coursework. I've recently installed Ubuntu5.10, I didn't install 6.06 as my computer has 256MD of RAM and thats the minimum required for 6.06(5.10 requires 128 min, I didnt want a slow system after insalling 6.06).

Ian using Anjuta1.2.4(its the only version that I've been able to get to work on Ubuntu5.10) for C/C++. I was reading SAMS Teach Yourself C for Linux Programming in 21 Days, theres a section on GUI programming using GTK. Iam trying to teach myself GTK...it sure has been a rough ride so far.

Here's the code that I am trying to compile
************************************************** *********************
/*a minimal GTK+ program - its from SAMS Teach Yourself C for Linux Programming in 21 Days*/

#include <gtk-2.0/gtk/gtk.h>

void destroy_func(GtkWidget *widget,gpointer data);

int main(int argc,char*argv[])
{
GtkWidget *main_win;
gtk_init(&argc,&argv);
main_win=gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_widget_set_usize(GTK_WIDGET(main_win),180,120) ;
gtk_window_set_title(GTK_WINDOW(main_win),__FILE__ );
gtk_signal_connect(GTK_OBJECT(main_win),"destroy",
GTK_SIGNAL_FUNC(destroy_func),NULL);
/*make sure window is visible*/
gtk_widget_show(main_win);
gtk_main();
g_print("About to exit main().\n");
return 0;
}
void destroy_func(GtkWidget *widget,gpointer pdata)
{
g_print("Quitting:Received destroy signal.\n");
gtk_main_quit;
}
************************************************** *********************

I have(among other things) gtk-2.0,glib-2.0,pango-1.0,atk-1.0,cairo in /usr/include, gtk2-engines(9 of them) are listed as installed in Synaptic, Synaptic also has libgtk 1.2, libgtk 1.2-common,libgtk 2.0,libgtk 2.0-bin,libgtk 2.0-common,libgtk 2.0-dev. However #include <gtk/gtk.h> gives me an error, saying that not such file or directory exists. I have tried using #include <gtk-2.0/gtk/gtk.h> instead but it gives me a long list of errors.
I have posted the complete list of errors here...srry its a long list, iam hoping it'll be of help to those reading the post...i think iam missing something here...like setting the path (using set path)on windows.

Hope someone knows how to fix this around here, hope Anjuta is the right IDE for working on GTK based apps. I am new to this, trying to find my around linux :)

Thanks

Install libgtk2.0-dev. You may also need other -dev packages; these are the packages that include the header files for the corresponding library.

[lnostdal]

i use this setup instead of anjuta:
http://nostdal.org/~lars/writings/ubuntu-programming1.pdf
http://nostdal.org/~lars/writings/ubuntu-programming2.pdf
http://nostdal.org/~lars/writings/ubuntu-programming3.pdf (this final part contains a howto get started with gtk+/glade)

but in general, regardless of ide/setup - you should use pkg-config to compile/link as shown in the last link above

edit: if glade-3 isn't available on breezy glade-2 will also work ..

hi,

thanks everybody for helping out, I have managed to install glade 2.12.0
along with all the dependencies through synaptic. The program i was trying to run in my initial post now works. Thank you, Lars Nostdal, your tutorials were really helpful. I am using anjuta and then manually compiling the .c file using
gcc -o file_name -Wall -g -std=c99 `pkg-config --cflags --libs gtk+-2.0`
file_name.c
below is code from inostdal's ubuntu-programming3.pdf...its not compiling...i have posted the error iam getting...looks like its having trouble recgnizing XML related function...how do i fix this???
================================================== =======================
#define _GNU_SOURCE
#include<stdlib.h>
#include<gtk/gtk.h>
#include<libglade-2.0/glade/glade.h> /*coz glade is in libglade-2.0 dir
and it doesnt recognize #include<glade/glade.h>*/

GtkSpinButton* spinbutton1;
GtkSpinButton* spinbutton2;
GtkLabel* label1;

void updateLabel(GtkWidget* widget,gpointer data)
{
char* sum_str;
asprintf(&sum_str, "%d",gtk_spin_button_get_value_as_int(spinbutton1)+gtk _spin_button_get_value_as_int(spinbutton2));
gtk_label_set_text(label1,sum_str);

thanks again for helping out :)

try:

gcc -o helloworld-glade -Wall -g -std=c99 `pkg-config --cflags --libs gtk+-2.0` `pkg-config --cflags --libs libglade-2.0` helloworld-glade.c

..the #include must be as in the pdf..

Hi,

I changed the header to glade/glade.h and used the new command for compiling- it compiled but it doesnt run...

thanks for helping out lnostdal, i think iam really close to getting this to work, what do i do next?

[lnostdal]

your .glade-file contains something that does not make sense:


(helloworld-glade:7665): libglade-WARNING **: Expected <glade-interface>. Got <GTK-Interface>.

the root of my .glade-file contains:


<glade-interface>


..while your contains as root:

<GTK-interface>

what glade are you using .. the 1.x one? .... start glade like this: press alt-f2 type glade-3 then press enter .. (edit: well, or at _least_ glade-2 .. but you should really upgrade ..)

[vk99]

hi,

alt+F2 glade3 - no go
alt+F2 glade2 - no go
alt+F2 glade - brings up glade 0.6.4

under Applications>>Programming: i have two links to Glade:
one says Glade and points to Glade 0.6.4
The other says Glade Interface Builder points to Glade 2.12.0

under /usr/include i have both libglade-1.0 & libglade-2.0

i used glade 2.12.0 to create the GUI.

[lnostdal]

right .. try doing

sudo aptitude install glade-2

edit: it's "glade-2" or "glade-3" .. not "glade2" or "glade3" ...

[vk99]

hi,

i did sudo aptitude install glade-2

so i downloaded glade3-3.0.0.tar.bz2 and did the sudo ./configure...sudo make...sudo make install routine. It installed itself. So right now i can alt+F2 to launch glade,glade-2 & glade-3.
Now, when i try the compilation code i get a new error

-------------------------------------------------------------------------------------------------

i have tried reinstalling libglade a couple of time through synaptic...it didnt work...so i went ahead and downloaded libglade-2.6.0...did sudo ./configure...it worked without errors...however when i did sudo make i get the same undefined reference to `g_object_ref_sink' error

i am lost, i think i am something wrong here :(

[lnostdal]

/usr/local/lib/libglade-2.0.so: undefined reference to `g_object_ref_sink'

that looks strange .. why is that file in the /usr/local/ -directory? or why does pkg-config refer to that file?

have you installed your own version of libglade or something? reason i'm asking is because stuff installed via ./configure && make && make install usually end up in /usr/local

this shows my setup, everything using ubuntu-packages:


lars@ibmr52:~/programming/lisp/swgtk$ pkg-config --list-all | grep glade

just upgrade to edgy and be done with it .. you'll find more updated packages there so you won't have to mess with this yourself

[vk99]

hi,

I managed to lay my hands on a Dapper Drake installation CD - its installed now, cudnt find edgy.

Installed libglade-2.0,glade-2.0,libgtk-2.0... the whole bunch. Iam getting a little mad at myself coz after all this...it STILL doesnt work!

heres the latest list of errors :(

Hello,

I followed the 3 .pdf files instructions and installed everything.

typed in the codes, and tried to compile and got these errors and warning.
Can you tell me why?

The code is from the first example on the 3rd pdf

CrazyTn:
you're using quote-characters: '
what you need to use is back-quote: `

like this: `pkg-config --cflags --libs gtk+-2.0`

edit:
you can copy/paste directly from the text by highlighting using your mouse then middle-press (or press both-mouse buttons at once) in the console (or any destination)

vk99:
you're still drawing the interface with an old version of glade .. or you're still using the old .glad-file

if you open your .glade-file in a text-editor you'll see that it contains <GTK-Interface> like described in the message:

lol I feel like a newbie.... I am so I guess that works out

Thanks

are there simpler ways to compile these programs?

[CrazyTn]

How would I compile without emacs?
Since I use vim

Is this the right script?


1 dbg = Environment(CCFLAGS = '-g -Wall -std=c99',
2 CXXFLAGS = '-g -Wall)

[lnostdal]

you start the build-process by typing scons -u at the console .. no changes to the SConstruct-file is needed .. you can call scons -u from any editor; just define a shortcut key that executes it

what you've pasted is not what the complete SConstruct-file should look like though

[vk99]

hi lnostdal ... thanks for being patient & sticking it out with me here :)
it worked...i goofed up earlier...used the same old glade file...made a new glade file and it works like a dream :)

i get these warnings

(helloworld-glade:6507): Gdk-WARNING **: locale not supported by Xlib

(helloworld-glade:6507): Gdk-WARNING **: cannot set locale modifiers


any ideas why?

[lnostdal]

do you get the same messages when starting other GTK applications from the terminal?

try to start gedit from the terminal for instance

edit:
i think i remember seeing this happen for GTK applications in general for both dapper and (early?) edgy

[vk99]

yeah looks like it happend for all GTK apps...those warnings showed up fot Gedit.

[CrazyTn]

in the guide, 2nd pdf

dbg = Environment(CCFLAGS = '-g -Wall -std=c99',
CXXFLAGS = '-g -Wall)

missing a ' after g -Wall

[CrazyTn]

I am getting this error:

main.cpp:11: error: 'delete_event' was not declared in this scope
I checked to see if I have the file gtk.h and found it, so I dnt know what is causing it.

from

g_signal_connect(G_OBJECT(mainWindow), "delete_event",
G_CALLBACK (delete_event), NULL);


I changed the above code to

g_signal_connect(G_OBJECT(mainWindow), "destroy",
G_CALLBACK (destroy), NULL);

destroy is defined before the main method.

so is there a reason why the first code didnt work?

[CrazyTn]

silly me I didnt define delete_event

nm

[lnostdal]

in the guide, 2nd pdf

dbg = Environment(CCFLAGS = '-g -Wall -std=c99',
CXXFLAGS = '-g -Wall)

missing a ' after g -Wall
thank you; this is corrected now
