[ERROR] No Linux lib files found during packaging for linux

I compiled UE4 4.3 in windows. I just wanted to test the packaging for linux. All the files semms OK and ine the corresponding directory. Even in the packaging option, the linux shown up.
But when I try to package for linux, it failes with corresponding message:

It can not find the exiting linux .so files.

Any idea, what’s going on?

It seems like you are trying to deploy a content-only project. You need to first build UE4Game binary for Linux (in Development or Shipping configuration - depending on what configuration you are packaging for).

The log messages about ICU are indeed worth investigating, but they aren’t the reason for packaging failure.
