error: 'ESP_PARTITION_TABLE_ADDR' undeclared

I'm trying to build the chooser. It seems to be getting stuck on building the bootloader, which surprises me, since this code hasn't been touched in 2 months, it seems.

The above snippet is from my second run. On my first make, I was prompted for lots of options, which I said n to all. You can see that full version here: full-make-error.txt
