c++ simple example not compiling under Fedora

mythcat · 10-24-2011, 04:49 AM

Hi i make simple C++ example.
This example is compiling with :

Code:

gcc test-gnome.c -o test-gnome `gnome-config --cflags --libs gnomeui`

...but i got errors with this command:

Code:

$ gcc test-gnome.c -o test-gnome -I /usr/include/gnome-1.0/ -L /usr/include/gnome-1.0/
In file included from test-gnome.c:6:0:
/usr/include/gnome-1.0/gnome.h:12:26: fatal error: gnomesupport.h: No such file or directory
compilation terminated.

I search and i not find the file gnomesupport.h
I use Fedora 15.
Can you tell what it is , or what is wrong.
Also I want use -I /usr/include/gnome-1.0/ , because it is in many distro...
Is true ?
If you have additional infos about how to compile same source code in many distro , please tell me.
Thank you . Regards.

On Fedora 15, you need to install the gnome-libs-devel package, which provides gnomesupport.h.

g++ rather than gcc

I thought that GNOME/GTK+ uses plain C.

Mine was a generic statement telling him that C++ needs g++.

test-gnome.c is a c file. I hope. If its c++ change the ending to .cpp.

And jhwilliams got the anwser to your problem. Install the dev file.

Ah, I didn't pay much attention to the topic, I just noticed that he's using "gcc", the source file name ends in ".c", and it's a GNOME program (and GNOME programs are written in C).

I have already the dev libs .
As I say :

Code:

gcc test-gnome.c -o test-gnome `gnome-config --cflags --libs gnomeui`

working fine.
My issue is about the way of compiling ... because i need to make this with :

Code:

-I /usr/include/gnome-1.0/ -L /usr/include/gnome-1.0/

The big question is way the first compiling line code ( ...--cflags) working well without gnomesupport.h and secondary compiling need this file ?

That's what 'gnome-config --cflags --libs gnomeui' does. Test it from command line:

Code:

gnome-config --cflags --libs gnomeui

Another (perhaps more modern) approach would be using pkg-config:

Code:

pkg-config --cflags --libs libgnomeui-2.0
