Netgear A6210 - compiling Linux driver

[Kasperczak]

I recently purchased the Network USB stick and am trying to compile the driver on Linux.  I am running on Linux Mint 19 (Ubuntu 18.04) and trying to follow the thread here:

https://community.netgear.com/t5/WiFi-Adapters/A6210-ADAPTER-ON-LINUX-UBUNTU/td-p/1062677

I downloaded the driver successfully but am getting an error on running make:

$ make
export DBGFLAGS

I am therefore unable to complete compilation. Can anyone help me with this please?

I think I have solved this problem by using the driver from here instead:

git clone -b port-to-4.15 https://github.com/kaduke/Netgear-A6210.git

This version compiled with some warnings but compilation completed successfully. After a 'make install' the A6210 was recognized and functioned correctly at least for a brief test.

Hi, I still get the same error as reported by the OP. Even following these instructions.
