Holy compilation marathon, Batman!
I knew qtwebengine was big, but that big? Although I had USE=-jumbo-build.
Has anyone measured how much jumbo-build reduces the compilation time? In percents? |
It's been a while since I actually tried, but I would still guess it should be about 50% of the time with 'jumbo-build' disabled (assuming the increased memory-use will not be a problem). |
Back in the days of jumboo-enabled chromium builds it was something like 7 hours compared to more than 35 hours for my poor old E6200 - dual core dual thread processor with 6 GB of RAM.

There was Qt Webkit [1], which kind of fell into slumber, and eventually lost its outside-Qt maintainers as well.
1. https://code.qt.io/cgit/qt/qtwebkit.git/ |
Chromium was initially based on webkit but that was more than a decade ago. That's why it was fast and compiled quickly. Then I abandoned Linux for a while and I don't know when it dropped the webkit part and became the monster that it now is.
Webkit itself was an internal Apple project that I think Safari was based on. It may still be.
p.s. I just checked because I remember something about KDE. Webkit is a fork of KHTML.

Ah. I didn't think that... Good (counter)point. ;)
Anyways... webkit-gtk seems quite lighter to compile: | Code: | | 2024-10-15T03:44:16 >>> net-libs/webkit-gtk: 5:38:39 |
.
I might as well now rebuild both with USE=jumbo-build... Let's gather some statistics.
