Slower build times in 4.8?

Henry_Read · July 9, 2015, 3:48pm

This commit still not integrate to 4.8 branch.

That CL missed the 4.8.2 cut-off date, unfortunately. It will likely be integrated if a 4.8.3 release gets planned.

That’s a really bad news…
We will stay with poor build times for weeks…

Is there a way for you to provide a “manual” patch for this? Isn’t it just the exe ou 1 dll to change?

Is there a way we can fix this? We don’t want to wait another month to get decent compile times…

Hello SentinelSigma,

Unfortunately until a version that is released that has this fix integrated, there is no way to workaround this in a binary version of the engine. If you are using a version of the engine built from source code however, you can feel free to integrate the commit (the GitHub link that he provided) into your source code instead of waiting for it to be integrated.

Hope this helps!

DO the patch have been included in 4.8.3?

Thanks,

Well it is not in the patch notes

Elvince · July 30, 2015, 10:04am

yeah… that’s so sad…
we will have to wait about 3 weeks to get this fix in 4.9

I have just updated to 4.8.3 and the build times haven’t changed.

So the current 4.9 preview also doesn’t have the patch?

anonymous_user_9051f221 · August 1, 2015, 12:00pm

As pointed out, this is not in the patch notes, and as I started using unreal engine now with 4.8 I had assumed that the compile times of 18 sec were normal…
Now I understand that they are not!
Any update as to the progress of this patch for the Binary build? And yes, I would really prefer not having to compile it myself…

maikklein · August 1, 2015, 2:14pm

Yes, it probably comes with 4.9, but I am not sure if it is in the current 4.9 preview.

maikklein · August 1, 2015, 8:51pm

Yay, the compile times are really fast in 4.9 preview 1. For my character.cpp it went down from 24seconds to 4seconds.

anonymous_user_9051f221 · August 1, 2015, 9:02pm

Good to hear, gonna download asap!

Jambax · August 1, 2015, 11:50pm

Haha, looks like I’m moving to 4.9 already then

anonymous_user_02360bb5 · September 13, 2016, 2:38am

I have similar issue using 4.13, UHT always run when i make a cpp change (like changing a letter inside a comment). It’s pretty annoying. Can someone help me make it work like it is supposed to. I use the engine from Github.
