I managed to make this work with the following steps:
[*]run
git log in arduino-esp32 to find the latest tagged IDF (3.1 in my case)
[*]checkout that tag in
esp-idf
[*]copy
sdkconfig from arduino-esp32/tools/sdk/sdkconfig to esp-idf/examples/get-started/blink/sdkconfig
[*]run
make menuconfig in esp-idf/examples/get-started/blink, turn on the options mentioned above
[*]make
[*]copy
build/freertos/libfreertos.a to
Arduino/hardware/expressif/esp32/tools/sdk/lib/
[*]copy
build/esp32/libesp32.a to
Arduino/hardware/expressif/esp32/tools/sdk/lib/
After doing these steps, I was able to compile this example:
https://www.freertos.org/uxTaskGetSystemState.html
with the following changes
[*]use
uxTaskGetNumberOfTasks() instead of
uxCurrentNumberOfTasks()
[*]hack the task status data out of memory. I've still messed something up because sizeof(TaskStatus_t) evaluates to 36, but the actual struct size in memory was 40. I offset the pointers manually. Please do pardon my language.

This forum is fine, but BBcode is an awful impediment. Good Night.
