Thank you all for your advice. One of the reasons I chose Code::Blocks was the form editor and it manages the make toolchain. Eric Tavenner ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: Porting Between Linux and Windows
Eric, I would suggest to go with Gtkmm [1] as it is the official Gnome C++ wrapper. It is pretty mature by now, has plenty of documentation, and used by a plethora of real world applications. The one I would recommend to look at and learn from is WorkRave [2]. You can quickly install and try it out both on Linux and Windows to explore the possibilities. Although, Gtk/Gtkmm is my personal choice,there are other C++ GUI toolkits to consider such as Qt [3] and wxWidgets [4] which might be tighter coupled with C++. Both have superb documentation and books written to help you started. In his latest book [5], Stroustrup uses FLTK [6]. Another angle to consider is commercial applicability. Here, along US Eastern Shore, you would be hard-pressed to find any Linux work that requires anything by Qt (sadly enough). By the same token, employers value Java [7] and C#/.NET [8] skills more than C/C++ these days. good luck, --Vlad [1] http://www.gtkmm.org/en/ [2] http://www.workrave.org/ [3] http://qt.nokia.com/products/ [4] http://www.wxwidgets.org/ [5] http://www.amazon.com/Programming-Principles-Practice-Using-C/dp/0321543726/ref=sr_1_1?s=books&ie=UTF8&qid=1340506852&sr=1-1&keywords=stroustrup [6] http://www.fltk.org/index.php [7] http://www.java.com/en/java_in_action/ [8] http://msdn.microsoft.com/en-us/vstudio/hh388566.aspx On Fri, 2012-06-15 at 17:33 -0700, Eric Tavenner wrote: > I am trying to teach myself C++.

To put the counter argument for someone who says he is a newbie, I think you are looking at this from the wrong direction. The GTK+ headers are in the subset common to C and C++, and can be used in either language (there is also no need to use gtkmm in C++, and sometimes good reasons not to do so). The real question is what language best suits the problem space the program is trying to solve. For some things, C++ is better (in my opinion). With C++11 auto variables, variadic templates and particularly lambda expressions, it is quicker to write code for some problem areas using C++ than C. The GTK+ code you write for a graphical interface will look pretty much the same in either language, if you are not using a wrapper, for the reasons I have mentioned. In other words, GTK+ is the servant and not the master in language choice here.

There are "Hello World" C source files in GTK documentation.

Fedora allows you to cross-compile with MinGW and I use Fedora myself to build 32-bit and 64-bit, Linux and Windows executables. I'd highly recommend you compile on one platform. It makes life much easier and you can use GDB on Windows for any debugging needs. Fedora carries GTK 2.24 for both Linux and Windows and I'd recommend sticking to this version as the Windows build of GTK 2.24 is very stable. Previous GTK versions were very unstable. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Yes, I have a largish C/C++ program which I can build for Windows and Linux from the same source code. I think the difficulty is likely to be in your build system rather than the source code. I've found building gtk programs on Windows rather painful. I build WIndows programs on Linux with a cross-compiler. > I have Code::Blocks 10.05 on both OSes, (Fedora 17 and Windows 7) on a 64 > bit machine. I've never used code blocks, perhaps it removes some of the pain from building on win. Try a hello world program and see if you can get it to build and run.
