Bug compiling MyGui 3.0 demos

Dear all,

I'm a new user to this forum, my name is Joaquim Duran.

I've downloaded MyGui 3.0 source and I've compiled it under Fedora 12 using OpenGL render. The library has been compiled with no problem but when compiling the demos this error appeared:


[ 49%] Building CXX object Demos/Demo_Colour/CMakeFiles/Demo_Colour.dir/DemoKeeper.cpp.o

cmake command: cmake -DMYGUI_RENDERSYSTEM=3 .

I would like to know if I could use MyGui to develop rich user interfaces (animations,...) in applications that are not games (as a replacement for Gtk or QT).

Thanks and Best Regards,
Joaquim Duran

Well, actually we implemented demos based on OpenGL for windows only right now. Renderer is cross-platform, but base demos code - not.
We had no experience with pure OpenGL apps and found no clear way to make cross-platform OpenGL application.
So if you familiar with OpenGL you can look at Common/Base/OpenGLBaseManager.h and Common/Base/OpenGLBaseManager.cpp and try to make it working under GNU/Linux. Everything else is cross-platform.

No, I don't have experience with OpenGL and X11 to port de OpenGL render to Linux. To test myGui I've changed the compilation and I've used Ogre lib. By recompiling the library and demos, the compiler (gcc 4.4.2) have detected an error: Ogre::UTFString stores its data in UTF-16, c_str return a pointer to uint16, meanwhile fstream need the path to file to open in UTF-8 and it needs a pointer to char. I've fixed the problem, compiles fine, but I haven't tested the change.

I've tested some demos, and I see that 3D acceleration is needed, for example Color demo was running at 2 FPS (with the current driver, I only 2d acceleration is available). It's very nice, but I don't feed my needs.

Hello,

Thx for patch. Applied.
