./build.sh command ends in ERROR: Can't reliably evaluate relative path without context: ../rmaker_common

[AC-Mike]

Maybe its because I'm using WSL on windows 11 rather than a real ubuntu install.

I deleted:

set(RMAKER_PATH ${CMAKE_SOURCE_DIR}/components/esp-rainmaker)
set(EXTRA_COMPONENT_DIRS ${RMAKER_PATH}/components/esp-insights/components ${RMAKER_PATH}/components ${CMAKE_SOURCE_DIR}/components/esp-insights/components)

from the CMakeLists.text file and it seems I have put the build in an infinite loop.

I'm trying to build the Arduino core so that mbedtls uses less heap. I have an active MQTT connection - also using mbedtls when I have to make a and https POST request.

Please no suggestions to use a different part with more memory. I have over 30K installed units that need an update.

The mbedtls documents say the memory profile is 48K heap. The mbedtls debug shows:

[ 7564][V][ssl_client.cpp:61] start_ssl_client(): Free internal heap before TLS 96496

The value returned from heap_caps_get_free_size(MALLOC_CAP_8BIT); just before the request is 50620 bytes.

Is the difference meaning the biggest block I can allocate of the 96496 available is only 50620?

I get this error from mbedtls:
[ 7697][V][ssl_client.cpp:316] start_ssl_client(): Performing the SSL/TLS handshake...
[ 8710][E][ssl_client.cpp:38] _handle_error(): [start_ssl_client():322]: (-16) BIGNUM - Memory allocation failed
