UE 4.19.2 packaging not possible. Can't produce UE4-UnrealEnginePython.lib

[bernhardrieder]

I've tried every possible constellation with either the embedded Python or a system-wide Python but I just can't package a game with the latest plugin version. I've also included an empty ue_site.py file like described in the readme.

My testscenario is a blank C++ project in UE 4.19.2 with the Python plugin.

This is my output log:

(I checked the ominous FSoftSkinVertex errors but couldn't detect any issues with that)

What am I doing wrong? Do I miss something?
Thank you very much in advance for the help!

I haven't tested or confirmed packaging yet. It's possible it is broken atm. Check the parent unrealenginepython branch and see if it packages for you, I might be missing a few upstream commits to ensure it compiles in monolithic mode.

Hi, first of all, thanks for the great work.
i also have the same problem, it wont let me package your fork, 20tabs works fine.
i use your fork because of the multithreading functions you added, unfortunately i cannot locate the changes you talk about here:
20tab#181
Anyways - realy cool work, i would be stoked if you could make it package somehow...
best,

Hey @sepppirch, do you still use UE4.19? I've integrated a changelist to fix the issues for UE 4.22 a while back, so that version should work if you get the latest code version. (Pull Request for that fix)
