Hi,

I cross compiled my project to run it on Linux (Debian 10.2). This is the server version of the project. The compilation seems to work but when I try to run the server (./GameServer-Linux-Shipping -log) I get the following error :  
“error while loading shared libraries: libApexFramework.so: cannot open shared object file: No such file or directory”

From my understanding, this concerns a Nvidia library used for physics.

This is pretty clear some libraries are missing, but I have some questions about it :

- Where can I get this library for my Linux server ? And where should I put those libraries ?
- Is there a way to include it in my packaged server ?
- If I don’t use Apex destruction, can I remove this dependency from my project ? How ? Maybe by disabling the plugin ? (I didn’t test this yet)

Any answer will be appreciated. Thanks 🙂

Hey,

It was 3 years ago but from what i remember my packaged project was missing this folder :  
`LinuxNoEditor/Engine/Binaries/ThirdParty/PhysX3/Linux/x86_64-unknown-linux-gnu/`  
with these files :  
`libAPEX_Clothing.so``libApexCommon.so``libApexFramework.so``libAPEX_Legacy.so``libApexShared.so``libNvParameterized.so``libRenderDebug.so`

So I think I found them in :  
`UnrealEngineFolder\Engine\Binaries\ThirdParty\PhysX3\Linux\x86_64-unknown-linux-gnu\`  
Then copied them to my package folder.

Hope it will solve your problem.

The issue was on UE 4.26.2 btw
