All Programs output distorted on certain angles

[Yamakuzure]

Hello everybody,

I would like to try out CrystalSpace, but can't even get the demo programs to run properly.

Everything compiles fine, but when I start walktest for example, it looks like this: Picture A. But when I turn around a bit I see this: Picture B.

My System:

• Version of CS : 1.4.0
• Version of winlibs package : none
• Operating system : Gentoo Linux x64
• Compiler : gcc-Version 4.4.4 (Gentoo 4.4.4-r2 p1.2, pie-0.4.5) [Thread-Modell: posix]
• Video card : Intel Corporation Mobile GME965/GLE960 Integrated Graphics Controller (rev 0c)
• Driver : (Video) Module intel: vendor="X.Org Foundation", compiled for 1.9.2, module version = 2.13.0 ; (OpenGL) 2.1 Mesa 7.9

Running with -verbose=-vcs (for taking those screenshots) printed out the following:

What could cause those distortions, and how can I get rid of them?

Edit: After doing some tutorials I noticed, that those distortions appear in all CS Apps. (see below)

[Yamakuzure]

I do not know whether this is of relevance but I tried CrystalSpace with the following versions of the nvidia cg-toolkit: (All with the same result)

• 2.1.0012
• 2.1.0016
• 2.1.0017
• 2.2.0017 (current version on my system)

[Yamakuzure]

While playing around with the Tutorials in the CS-1.4 Manual, I had to witness the same distortions. It should look like in Picture A and when I move around a bit it looks like Picture B.

This is starting to get really frustrating, because I can't find the reason for that.

One additional thing:

I have to configure CrystalSpace with "--enable-make-emulation". When I try compiling without make emulation (aka using system jdk?) the compilation fails with:

But this can't be the reason, can it?

Java version : sun-jdk-1.6.0.22

JAM version : ftjam-2.5.3_rc2-r1


btw.: This warning about "suggest parentheses around assignment used as truth value" appears 835 times, and *only* if I try to build CrystalSpace without make emulation.

Hello,

  about the graphic glitches, it may well be due to the generally poor quality of
Intel graphic cards or driver. I'd suggest you to show this post with pictures
to people (especially res/res2k) in the #crystalspace IRC channel on chat.freenode.net server.
Maybe that's fixeable, but that will require quite some follow-ups with people in the know
(eg. debug shaders, using tools like buGLe, ...)

For the Java related errors, it may be due to your Swig versions being too recent.
You could either try using Swig 1.3.33 or maybe 1.3.36, or disable it,
so that the pre-generated files (present in CS source) are used.

[Yamakuzure]

Hi, and thanks for the reply!

Well, I surely suspected the intel drivers. But I made some tests, and everything else works fine. I tested GLFrontier, Briquolo (OpenGL), FreeOrion (Ogre3D) and all Irrlicht demos. (The latter look like this, this and this.)

*Sigh*

I guess it has something to do with CXXFLAGS. So I will rebuild CrystalSpace today without any additional flags, and see whether the issue goes away. If it does, I can add single flags until the distortions re-appear. If not, I'll go and look what the people on IRC say.

For the java issue, the lowest version of swig directly available on gentoo linux is 1.3.40. But it's not a problem, because CS compiles fine with "--enable-make-emulation".

[Yamakuzure]

Nope, it is no compilation issue due to C(XX)FLAGS or LDFLAGS... *sigh*
