Hello all.

The GTK examples work after installing the now more hard to find GTK/Glib 1.2. Even so, I get this error:

Code:
$ ./button

Gtk-WARNING **: Failed to load module "libcanberra-gtk-module.so": libcanberra-gtk-module.so: cannot open shared object file: No such file or directory
Button was clicked...

Button was clicked...

closing application...
$
    


A fix for this is to do:

Code:
$ unset GTK_MODULES    


However anyone who uses the program may have to do this, until the next Linux update breaks it completely.

What changes are needed to make them current? I want to use these templates in my first programs.

Hi,

I assume you're using the gtk-button example. I got it working by doing the following.

1) Install libgtk2.0-dev (at least that's what it's called on Ubuntu)
2) Install the program pkg-config if you haven't already got it.
3) Change the second line of "makefile" to read:

Code:
gcc -Wall -s -O3  button.o -o button `pkg-config --cflags gtk+-2.0` `pkg-config --libs gtk+-2.0`
    


4) open "button.asm" and change this:

Code:
extrn gtk_signal_connect
    


to this:

Code:
extrn g_signal_connect_data
    


Now change the two calls to gtk_signal_connect so they read:

Code:
    ccall g_signal_connect_data, [hWindow], szDeleteEvent, DeleteEvent, dword 0, dword 0

    ccall g_signal_connect_data, [hButton], szClicked, ButtonClick, dword 0, dword 0

I don't know why it doesn't work in Fedora 32, any ideas?
Code:
[mythcat@desk fasm]$ ./fasm.x64 button.asm button.o

[mythcat@desk fasm]$ ./fasm button.asm button.o
...
[mythcat@desk fasm]$ gcc button.o $(pkg-config --cflags --libs gtk+-3.0) -o button

When all else fails, read the source

I suspect you need to tell GCC to output a 32-bit file. Or you might need to link it to a 32-bit library. Or both.

Use -m32 when invoking gcc.

The c source code with GTK simple button works ... and the run of the result ...
Code:
[mythcat@desk fasm]$ gcc -Wall -g  `pkg-config --cflags gtk+-3.0` test.c -o test `pkg-config --libs gtk+-3.0`
    

Why not this ?
Code:
[mythcat@desk fasm]$ gcc -Wall -g  `pkg-config --cflags gtk+-2.0` button.o -m32 -o button `pkg-config --libs gtk+-2.0`
/bin/ld: cannot find -lpangocairo-1.0
/bin/ld: cannot find -latk-1.0
/bin/ld: cannot find -lcairo
/bin/ld: cannot find -lpangoft2-1.0
/bin/ld: cannot find -lpango-1.0
/bin/ld: cannot find -lharfbuzz
/bin/ld: cannot find -lfontconfig
/bin/ld: cannot find -lfreetype
collect2: error: ld returned 1 exit status
[mythcat@desk fasm]$ gcc -Wall -g  `pkg-config --cflags gtk+-3.0` button.o -m32 -o button `pkg-config --libs gtk+-3.0`
/bin/ld: cannot find -lgtk-3
/bin/ld: cannot find -lgdk-3
