Question

How do I get rid of the console when writing GUI programs with gtk in C?

Answer 1

+1 A:

When you link, use the argument -mwindows

gcc -o simple simple.c `pkg-config --libs --cflags gtk+-2.0` -mwindows

Thanks!Let me try if it works. What about the `GLib-WARNING` issue?

Seems it's not working for windows. Though I've installed gcc environment already.

Gtker 2010-05-02 05:54:50

No idea about that; as it's a warning, I'd probably just ignore it.

Matthew Talbert 2010-05-02 05:55:28

What isn't working?

Matthew Talbert 2010-05-02 05:56:10

But there will be thousands of the same warning as long as I don't cancel right click on the icon.

Gtker 2010-05-02 05:56:46

It reports: `gcc: `pkg-config: No such file or directory`,`gcc: gtk+-2.0`: No such file or directory`

I was just copying from the tutorial you linked. Presumably you've successfully compiled it before? Just do what you already did and add the "-mwindows"

Matthew Talbert 2010-05-02 05:59:14

I'm using cmake to build, and it can't recognize the -mwindows switch: `set(CMAKE_CXX_FLAGS "-Wall -mwindows")`

Gtker 2010-05-02 06:02:41

It wouldn't be CMAKE_CXX_FLAGS. I don't know CMAKE, but it would possibly be something like CMAKE_LXX_FLAGS (Look for "L")

Answer 2

A:

The console opens then an application outputs text (which perhaps was obvious). By default the application outputs text then an error occurs. Use g_set_printerr_handler() change that behaviour (into displaying an error dialog, writing to a file or whatever you want).

That's not the problem; on Windows, gcc builds console binaries by default, which open a console whether text is output or not. You have to link with the `-mwindows` switch to get a binary that doesn't open a console, as in @Matthew Talbert's answer.
