[OpenWrt-Devel] broadcom-wl @ bcm63xx fails on kernel 4.19

Thu Apr 2 11:18:43 EDT 2020

Hi all,

since bcm63xx still has 4.19 as testing kernel for five months already, I today tried to build it.

Interestingly, the build fails for package/kernel/broadcom-wl, and this issue persists even when I go back to the initial commit introducing 4.19 support (so, the problem is no regression).

For some reason, the problem seems to not affect bcm47xx, which uses kernel 4.19 as default ATM.

Since I have no idea what broadcom-wl does, I cannot provide much more than the build errors below.

Best

Adrian
