[Glade-users] gtkbuilder and textview - I'm confused

[David Buchan]

Hi guys,

I'm using Glade 3.6.7 on Ubuntu linux and writing a program in c language.

This is likely going to be a dumb question, as I'm new to Glade. Regardless...

I've created a simplified example to illustrate my problem.

I have a UI which consists of window1 which contains a single textview (textview1). In Glade, I added the buffer to be textbuffer1. I saved the file as gtkbuilder format.

Running my makefile results in the following output:

gcc -Wall -g `pkg-config --cflags gtk+-2.0 gmodule-2.0` -c main.c
main.c: In function ‘main’:
main.c:31: warning: ‘textview1’ is used uninitialized in this function
gcc -Wall -g `pkg-config --libs   gtk+-2.0 gmodule-2.0` main.o -o textview

I haven't figured out how to fix that warning but I suspect it is not something to be ignored.

Running the compiled program with./textview results in a seg fault.

gdb has this to say:

(gdb) file textview
Reading symbols from /home/textview/textview...done.
(gdb) r
Starting program: /home/textview/textview 
[Thread debugging using libthread_db enabled]

Program received signal SIGSEGV, Segmentation fault.
0x008531b0 in g_type_check_instance_cast () from /usr/lib/libgobject-2.0.so.0
(gdb) bt
#0  0x008531b0 in g_type_check_instance_cast () from /usr/lib/libgobject-2.0.so.0
#1  0x08048b92 in main (argc=1, argv=0xbffff4b4) at main.c:31

Can anyone clear up my confusion?

The program (textview.c), Makefile, and gtkbuilder file are attached.

Thanks,
Dave
