Newbie to Programming

[royoni]

Hi,
I am new to Linux C++ programming and I use Anjuta + Glade on FC2.
I would like to make my first little programme which simply open an image then display it on the same window.

Please advise what is wrong on the screen shot and the error message, thank you very much!

I think you'll probably get better help in a more Glade-oriented forum than here, since these fora are more oriented to helping people with Fedora-specific issues.

Thanks cracker,
but where can I find such kind of forum?
can you post a URL?

[imdeemvp]

did you do a google search? but if you did not here is the glade home page

you may find your answer there..........

How are you compiling this program, with a makefile? The problem seems to be that the header file that defines PixbufLoader is not included.

Thank you all! Is this the header file you mean? #include <gdk/gdkkeysyms.h>??
How can I search for the correct header file for Pixbufloader??

[PompeyBlue]

The joy of getting somebody else's code to compile on your machine. The way I find lost functions is to go the include directory for whatever I'm working on (XLIB or GLUT) and simply:

grep -I <symbol> *.h

This will search all header files for whatever symbol you are looking for. So in your cash I think you need to cd to the gdk header directory and then

grep -Ii Pixbufloader *.h

The -I mans all files, -i means ignore case.

It will either tell you which header file it's in or if it comes up blank it suggests that it's probably part of the application source that you are trying to compile.

[PompeyBlue]

Oh yeah, it could also be a namespace problem, it could be compiled under std, not gdk and that's why it's not finding it ?

Thank you!
I did find the following pixbufloader.h files in my system, but I don't know how to configure Anjuta to look for the correct directory while compiling? (Since these files are in the gtkmm directories instead of gdk!)

Please advise,
