Rtl8812au: Installation fails under Linux Mint 19, kernel 4.15

[cristianav]

Hello,

First of all, many thanks for all your work, much appreciated.

Now, I'm trying to install the drivers but I'm stopped at this step:

Any idea about this?
Thanks

Thanks, did you try using "make && make install" instead of DKMS ?

[cristianav]

Yes, both ways but the same result.
Is maybe the compiler too old or something like that?

Thanks for your reply.

@CGarces may you add some Linux Mint checks to Travis? Added you to README.md under credits btw 🥇

[kimocoder]

I'll fix 1 issue shortly, then Mint check should/will be added to Travis CI for watching. I'll notify you when I push a minor compiler fix

[CGarces]

"Mint check"?

I can add checks for some scenarios, but not for one specific distribution. Please point me to the commit that fix this issue and I'll try to understand the problem.

[kimocoder]

I have no idea on Travis 😅 I'll boot up a virtual Mint, it's Ubuntu based so it can't be that serious, just don't have more time right away

I had the exact same error while building this module on a 4.14 kernel.
It appears that the function cfg80211_sinfo_alloc_tid_stats() was introduced in 4.18 with this commit.
The v5.3.4 is building on this kernel.
