Build fails on Ubuntu with kernel 6.8.0 #363

Closed mareklab closed 1 week ago

Just to let you know, the build fails on Ubuntu 24.04 TLS with kernel 6.8.0, I've tried both the latest gcc-13 and older gcc-11

Then it works fine on the same Ubuntu 24.04 TLS with my previous kernel 5.15, built with gcc-13

Some compiler bug. What arch and RAM size ?

mareklab commented 1 week ago

64-bit, RAM 4 GB, CPU i3, SSD

If it's compiler bugs, why the same compiler works fine with kernel 5.15?

crazycat69 commented 1 week ago

swap enabled ? https://github.com/tbsdtv/linux_media/issues/358

mareklab commented 1 week ago

Sure. Let me test the swap utilization when it fails... (update coming soon)

mareklab commented 1 week ago

Okay, you were right. The problem is make -j4 - since it runs 4 processes at once, it requires a lot of RAM to finish all build tasks.

There are 2 solutions: either just run make, or increase swap size (5GB worked for me, it failed with my initial 1GB)

Thanks for the hint!
