Dear buildroot developer,
I'm using buildroot 2024.02.1 with top-level parallel build, and found in
the last step of my build - "Rebuilding kernel with initramfs" - it throws
the following warning and makes the kernel rebuilding single threaded.
*make[1]: warning: jobserver unavailable: using -j1. Add '+' to parent
make rule.*
The previous version 2023.02.4 didn't have this issue. And, I found this
commit: linux: use BR2_MAKE · buildroot/buildroot@0b9efc9 · GitHub
<https://github.com/buildroot/buildroot/commit/0b9efc991f8a2c1b6388e4e575641228262eadd1>,
which changes $(MAKE) to $(BR2_MAKE)". I reverted the change in line 645
back to $(MAKE) in my repo, and the warning was gone, and the kernel
rebuild was in multi-thread again.
Wondering if I missed something in the buildroot configuration or this part
of BR2 code needs some revision? Thanks for your help!
Best regards,
Sam
