  1. POInstalling and Linking PhysX Libraries in Debian Linux
    text
    copied!<p>I am trying to get PhysX working using Ubuntu.</p> <p>First, I downloaded the SDK here:</p> <ul> <li><a href="http://developer.download.nvidia.com/PhysX/2.8.1/PhysX_2.8.1_SDK_CoreLinux_deb.tar.gz" rel="nofollow noreferrer">http://developer.download.nvidia.com/PhysX/2.8.1/PhysX_2.8.1_SDK_CoreLinux_deb.tar.gz</a></li> </ul> <hr> <p>Next, I extracted the files and installed each package with:</p> <pre><code>dpkg -i filename.deb </code></pre> <p>This gives me the following files located in /usr/lib/PhysX/v2.8.1:</p> <ul> <li>libNxCharacter.so</li> <li>libNxCooking.so</li> <li>libPhysXCore.so</li> <li>libNxCharacter.so.1</li> <li>libNxCooking.so.1</li> <li>libPhysXCore.so.1</li> </ul> <hr> <p>Next, I created symbolic links to /usr/lib:</p> <pre><code>sudo ln -s /usr/lib/PhysX/v2.8.1/libNxCharacter.so.1 /usr/lib/libNxCharacter.so.1 sudo ln -s /usr/lib/PhysX/v2.8.1/libNxCooking.so.1 /usr/lib/libNxCooking.so.1 sudo ln -s /usr/lib/PhysX/v2.8.1/libPhysXCore.so.1 /usr/lib/libPhysXCore.so.1 </code></pre> <hr> <p>Now, using Eclipse, I have specified the following libraries (-l):</p> <ul> <li>libNxCharacter.so.1</li> <li>libNxCooking.so.1</li> <li>libPhysXCore.so.1</li> </ul> <p>And the following search paths just in case (-L):</p> <ul> <li>/usr/lib/PhysX/v2.8.1</li> <li>/usr/lib</li> </ul> <p>Also, as Gerald Kaszuba suggested, I added the following include paths (-I):</p> <ul> <li>/usr/lib/PhysX/v2.8.1</li> <li>/usr/lib</li> </ul> <hr> <p>Then, I attempted to compile the following code:</p> <pre><code>#include "NxPhysics.h" NxPhysicsSDK* gPhysicsSDK = NULL; NxScene* gScene = NULL; NxVec3 gDefaultGravity(0,-9.8,0); void InitNx() { gPhysicsSDK = NxCreatePhysicsSDK(NX_PHYSICS_SDK_VERSION); if (!gPhysicsSDK) { std::cout&lt;&lt;"Error"&lt;&lt;std::endl; return; } NxSceneDesc sceneDesc; sceneDesc.gravity = gDefaultGravity; gScene = gPhysicsSDK-&gt;createScene(sceneDesc); } int main(int arc, char** argv) { InitNx(); return 0; } </code></pre> <p>The first error I get is:</p> <blockquote> <p>NxPhysics.h: No such file or directory</p> </blockquote> <p>Which tells me that the project is obviously not linking properly. Can anyone tell me what I have done wrong, or what else I need to do to get my project to compile? I am using the GCC C++ Compiler. Thanks in advance!</p>
