AllBulletDemos & Linux

[Enrico]

Hi,

I just got the new Bullet 2.64 and the "AllBulletDemos" does not compile with GCC 4.x (tested on AMD64 and x86):

Code: Select all

In file included from Demos/AllBulletDemos/Main.cpp:21:
./Extras/glui/GL/glui.h:377: error: ISO C++ forbids declaration of ‘GLUI_Rollout’ with no type
./Extras/glui/GL/glui.h:377: error: ‘GLUI_Rollout’ declared as a ‘virtual’ field

Demos/AllBulletDemos/Main.cpp: In function ‘void Resize(int, int)’:
Demos/AllBulletDemos/Main.cpp:68: warning: unused variable ‘ratio’
Demos/AllBulletDemos/Main.cpp:46: warning: '<unnamed>::z' defined but not used

With GCC 3.2.3 it compiles and works

All in all it would be better to use a maybe available GLUI installation. Most Linux distributions come with GLUI and GLUI-dev packages, so it should be no problem. Don't care for Windows though

I have seen some new warnings...I will see if I can find time to fix them



Best regards,
Enrico

Bullet includes a modified version of glui that doesn't require run-time type checking (RTTI).

It should be a simple fix, can you try if the latest SVN version works fine (or attached glui.h) ?

Thanks for the report,
Erwin

Great, works now

Find attached a patch which removes some unused variables in the bullet library. I will look at the demos later.

Are you interested in some more documentation, maybe for the wiki? I have written lots of notes (for myself) about what a physics engine is, what it does, what it does not, basic principles of physics and stuff like that...
