Ryan,

does that mean that I don't need freeglut for building apps using klimt? If so (I can't believe) what's the difference and why do I (might) need freeglut?

Georg

Georg,

That is correct, freeglut is not required for building apps directly using Klimt, anymore than you need to use freeglut on your PC to build OpenGL apps. It just provides a windowing toolkit with event handling and some additional utility functions. From the freeglut homepage  "GLUT (and hence freeglut) allows the user to create and manage windows containing OpenGL contexts on a wide range of platforms and also read the mouse, keyboard and joystick functions."

If you look at the examples provided in the source archive, you'll find examples of both types of applications. simple_linux_qte and KlimtDemo_qws, in the klimt/test directory, just use libKlimt and the regular Qt api. The test appliction in the freeglut/test directory uses the GLUT api to perform a similar task.

Ryan

Ok, I will try klimt first to go on with freeglut thereafter ... as soon as there's enough time for it - too much work at the moment :-(

thank you. Now I can compile but then the linker fails with 'cannot find lXext' although XFree86-devel is installed and the libs (libXext.a and libXext.so) are in the X11-libs-dir.

Georg,

Looks like its still pulling native libraries in... linking againt Qt/Embedded does not require any X libraries to be present at all... and in fact linking against them is generally a sure fire way to have your app fail when you try to run it on the Z.

Ryan

Ryan,

finally I made it (somehow) to build a freeglut.so. Could you please be so kind and
explain the dependencies and meanings of the several libs contained in your source-package to me? What are the minimum requirements to use klimt on the
Z5500? I can't await to start with that stuff ... g*

Thanks a lot,
Georg

Ryan,

I see, probably I'm mixing up something with my dev-configuration. Which libraries/includes do I need for building freeglut/klimt? I'm using qt-emb. 2.3.7
for my other qpe-projects - is that ok for klimt?
Thanks,
Georg

Georg,

I'm running a self compiled version of Kdevelop from CVS, but that shouldn't matter, as you can manually run qmake to build the makefiles assuming you have the correct qmake setup.

Extract the attached qws.tgz somewhere, and then either export the QMAKESPEC environment variable to ${PATH_WHERE_YOU_EXTRACTED_IT}/qws/linux-sharp-g++ or specify that on the qmake command line with the -spec argument. You'll have to set your QTDIR variable to your qt/embedded directory first to ensure you dont pull in any native qt3 directories.

Ryan

Ryan,

Hi,

it's quite interesting for me what you're discussing about. I'm thinking about
implementing a terrain modeler for my (and others) Zaurus 5500 for visualization
of DEMs. I'm running OZ3.3.5. I just tried to compile klimt for linux ... but I failed when
building freeglut. Does anybody have a collection of all (working) required sources to
build klimt for Linux and QPE?
Thanks,
Georg

Georg,

What errors do you get when trying to build it? The source archive I posted is a straight copy from my work directory, and it all builds fine for me in there. The only other requirements to build it would be a working development enviroment AFAIK.

Ryan

Hi Ryan,

in the meanwhile I've found your sources but I still can't build the libs. Which KDevelop version do you use? I'm using 2.1.5 so that I can't use your project files. I tried to
build freeglut_qws with qmake and the .pro file. Make fails with something like 'no rule defined to build /usr/lib/qt3/mkspecs/qmake.conf'. I don't intend to upgrade to KDevelop 3.0.x at the moment because then my Zaurus-Dev-Env. might not work anymore. Any suggestions?

Thanks,
Georg

Ryan,

sorry, I'm new in the forum. I tried it using the sources from freeglut's website.
Where can I find your sources? My development environment (KDevelop) works
fine for my other qpe-projects ...

Thanks,
Georg
