Hi,

I'm trying to build the mt7610u driver from https://github.com/ulli-kroll/mt7610u/

It fails with multiple kernel versions and always at the same file:

Code:

This seems to be a Gentoo specific problem as I don't have any problems building the module on Debian.

I reported this on the upstream repo, but got no response so far: https://github.com/ulli-kroll/mt7610u/issues/79

Any ideas on what to do?

From https://github.com/jurobystricky/Netgear-A6210/issues/36 it's talking about 4.9 series kernel, but probably still applies.

Code:

I fixed that error by enabling CONFIG_WIRELESS_EXT in the kernel. You cannot enable it directly though, you have to enable some wireless module which pulls CONFIG_WIRELESS_EXT in.
The module compiles now.

When you built the module on Debian, did you use the same configuration as you used on Gentoo? If not, then it's not an accurate comparison. Looking at the source, the issue that Anon-E-moose found seems to apply in v4.17 as well.

I was just wondering, why it worked on Debian, but not Gentoo.

You are right of course, I was using the stock kernel from Debian, so it includes CONFIG_WIRELESS_EXT.

On the other hand I had removed all of the in-tree drivers for WIFI in the Gentoo config. :?

So it's not a Gentoo specific problem after all.

Thank you both very much! :D

I tried your suggestion and now the driver builds successfully.

I enabled CONFIG_IPW2200 (Intel PRO/Wireless 2200BG and 2915ABG Network Connection) which did the trick just fine.
