Bluetooth examples don't build after pulling latest from github

[PaulELong]

I'm trying to track down a bug in the ESP code, so first I wanted to see if it's addressed already so I pulled from master. After the pull, I'm no longer able to build my project. I tried building the hello_world from the examples, and that worked. However, the bluedroid/ble examples don't compile and get the same error: "..esp-idf/components/esp32/cpu_start.c:430: undefined reference to `coex_pre_init'.

I reran the install.ps1 and exports.ps1 before building. I also did a idf.py fullclean which didn't help. I also ran menuconfig, though didn't make any changes, and that didn't help either.

Can you help me fix my build?

Thanks -Paul

Here is the output from building gattc_muilti_connect:

I fixed the issue wiping out the esp-idf directory by redoing all the steps again. Not sure what happened, but it's working now.
