Error building usb-can. 'struct can_frame' has no member named 'len'. #43

Closed Umaroth8419 closed 1 year ago

Umaroth8419 commented 1 year ago

Hi there! I'm trying to build usb-can on kernel 5.10.110-30-rockchip-g12ee46f17a0c. When I run build, I get error: 'struct can_frame' has no member named 'len'. Unfortunately with this sbc, we're all stuck on the older kernel. Is there a way to go about fixing this? I'm trying to run usb-can upon boot so I can communicate between the sbc and a board with a transceiver on the toolhead of my 3d printer! The SBC in question is Rock5B. Thank you!

Hi, have you tried building with the 5.13 or 5.15 branch? They might work for 5.10 too. If not I can look into fixing it but it will be end of the year because I'm on vacation at the moment

I haven't tried building for 5.15 branch. I'll try it. If not I'm SoL. Then I'll have to return this adapter and use mcp2515 adapter instead.

Doesn't work. Could this be because of the new socketcan version? Why wouldn't len be found in can.h?

alexmohr commented 1 year ago

The socket can interface changed a lot over the last few kernel versions. I skipped someintermediate versions because I never tried to target 5.10. It can't find Len because the interface doesn't contain it on 5.10 due to the changes.

I think your best choice at the moment is to use a different adapter. I might be able to look into this at the end of December. Bit I'm definitely not able to get to this any earlier.

It should now work again with 5.10
