Build 1.12 with ESP-IDF 4.1 stable.

How build micropython with ESP-IDF 4.1 stable, im give error:

make BOARD=GENERIC_SPIRAM

kconfiglib.KconfigError: /root/micropython-1.12/ports/esp32/esp-idf/Kconfig:166: '$COMPONENT_KCONFIGS_PROJBUILD_SOURCE_FILE' not found (in 'source "$COMPONENT_KCONFIGS_PROJBUILD_SOURCE_FILE"'). Check that environment variables are set correctly (e.g. $srctree, which is set to '/root/micropython-1.12/ports/esp32/esp-idf/'). Also note that unset environment variables expand to the empty string.

MicroPython has to be built at specific versions of the IDF as they make breaking changes between versions.

To move to 4.1 requires some changes to MicroPython's ESP32 port. See https://github.com/micropython/micropython/pull/6413 for a starting point.

Ok thanks, but i have next problem in 1.12 and 1.13 is the same:

A specific MicroPython version must be built against a specific ESP-IDF version.

Current MicroPython (i.e. v1.13 and the current master) only work with ESP-iDF v3.3.2 and v4.0.1

If you want to use ESP-IDF 4.1, you must update MicroPython code to match the corresponding changes in 4.1. Otherwise it will not compile. The pull request I linked to is an example of the sort of changes that are involved.
