cmake errors, cant find bullet root?

[flintFred]

trying to build osgbullet, cmake is displaying errors:

what are the needed enviroment vars? or anything else?

cheers.

I'm assuming you got past your osgWorks build issue?

For info on finding Bullet, see the wiki:
http://code.google.com/p/osgbullet/wiki/BuildingOsgBullet#Finding_the_OSG_and_Bullet_Dependencies

Updates would be appreciated, if you find any info is out of date.

yes osgWorks now build fine.

if i manually set the bullet lib and include directorys within cmake,
then when i come to visual studio i get errors with the bullet
headers,

#include <somebulletheader>
if i change the include to #include "somebulletheader" (change <> to
""'s)
then it will compile, but theres a lot of headers to change.

So im guessing its all about environment vars.

I have BULLET_ROOT and BULLET_HOME and BULLET_INCLUDE_DIR set within
my enviroment vars.

anything else?

If you think you need to change the source code just to get it to compile,
please look for another solution. osgBullet builds fine as it is for several
users on all three major platforms.

The FindBullet.cmake script that comes with CMake (which osgBullet uses) is
usually in a location like this on Windows:
C:\Program Files\CMake 2.8\share\cmake-2.8\Modules\FindBullet.cmake
I do believe it supports environment variables to help find Bullet.

In that script, you can see that it sets BULLET_INCLUDE_DIR to the directory
that contains the file btBulletCollisionCommon.h. osgBullet's CMake script just
adds ${BULLET_INCLUDE_DIR} to the list of directories to search for header
files. So, osgBullet source might have something like this:
#include <BulletCollision/CollisionDispatch/btCollisionObject.h>
I believe this is correct because BulletCollision is a subdirectory of the
directory that contains btBulletCollisionCommon.h.

Does that help?

Thanks.

I managed to get osgBullet to compile, I manual added the bullet lib
and headers.
I was adding C:\Program Files (x86)\BULLET_PHYSICS\include when it
should be C:\Program Files (x86)\BULLET_PHYSICS\include\bullet

It works, that will do , am happy now.

Thanks Paul.
