Hmm, oddly enough you've only got static libraries there... but you do have gtk (libgtk.a). You would also need to check /usr/include though - if you don't have the include files for the libraries, you can't use them, and it's possible to install them without having the include files (several binary distributions do this - such as Red Hat, where to develop GTK software you need to install the gtk package, and gtk-dev as well).

Yeah, I only listed the static ones. Are any of these libraries likely to use dynamic ones? If so, I can make a bigger list. However, I'll check out gtk tomorrow. Thanks.

thanks.

Development's usually done by linking to dynamic libraries. I assume you have them anyway.

Ah, OK. I'm still getting used to linux/unix programming having mostly used visual c++ which makes it far too easy to not know about exactly what is going on with things like that.

One of the reasons I don't like it...

You't think how I feel, I've only developed in Visual C++ a little, most of my windows work was in VB (for 7 years) thats along time to get used to some things, and it took me a while just to get used to the Curly braces . I'm OK with C++ and C now, but I'm not sure how to aprotch Linux programming.

because I could do with porting a few things.

Linux programming is immense, probably down to there being absolutely no standard GUI libraries whatsoever. GTK+ and Qt are the most common for new stuff at the moment though.

You young kids and your fancy "Graphical User Interface"... Back in my day all we had was the command line. And we liked it!


Seriously though, you can directly compile ANSI C console applications in Linux without changing much. That doesn't really help with GUI, but...

If you don't need a grapical user interface just fire up a copy of vim, emacs, or and start writing your C code. And remember, printf is your friend.

Funny you should say that, my friend made a Turing Machine emulator for windows, and I made a binary adder, if that isn't going back to you roots, I don't know what is.

GUI shouldn't be that hard, surly?

-- DoctorMO --

No idea. I've never done GUI in Linux, only console.

Ah! Don't mention Turing Machines! I've been learning all about Alan Turing and Church-Turing, and am up to eye ball with it.

As far as Graphics are concerned, I have attempted to write ordinary c programs using BGI graphics using Borland in Windows but I always get an error, which wont let me run the program. I would be interested how to get around this as well.

MaW, thanks for the gtk recommendation. They do indeed have the relevant header files for it and (at the very least) the simplest program at the beginning of the gtk tutorial compiles and runs fine on at least one of the department computers. (This is enough because I can always ssh to this one from wherever I am in the department.) However, I've also just discovered that allegro can be installed and used as a non-root user as long as you don't use the direct memory access routines (which is fine because I can run it in windowed mode).

Woohoo! That's excellent news.

The good thing about GTK+ is that it's got a fairly decent API. Personally I use gtkmm, the C++ wrappers for it, which has an even more decent API that knocks anything Microsoft have ever produced into a cocked hat, but that's just me, and of course gtkmm might not be installed for you.

Although you can install and use it as a non-root user if you wish

I gotta learn about the GTK.

Whenever possible I write console applications. A GUI interface can be added later... look at the way WinCVS is just a front end to the regular cvs executable...

Sometimes you just have to write something GUI-only though - especially if you're the one writing the frontend for someone else's console program

Good point.

hmmm yes
