Incredibuild hangs during linking when building engine from source


This happens very consistently whenever trying to link various engine dlls. The link appears to take forever. For example, I left one evening letting a build run overnight, and came back in the morning to see that it was trying to link an engine dll for 16 hours. Stopping the build and then starting the build again seems to consistently get past the hang, but you sometimes have to do this 3 or 4 times to get through a full rebuild.

What’s going on?

I am building 4.10.2-release - 498016edc91a76b30f29f4f2caa752be68ed3e89 with visual studio 2015 Version 14.0.24720.00 Update 1 and incredibuild version 7.12 (build 1679)

Hi nteymory,

There was a bug in Incredibuild that resulted in an Engine build sometimes getting stuck on a file indefinitely. This should have been corrected in version 7.11 of Incredibuild, but you need an updated Windows UCRT as well. I do not believe this has been released as a Windows update yet. You can download the new UCRT here.

Try installing the new UCRT and see if that helps with the issue you are experiencing.

It looks like this has solved the problem. Thanks !
