Zepyhr: make PRESET=ZEPHYR fails #103

Closed mikevoyt closed 4 years ago

mikevoyt commented 4 years ago

v1.0.2 fails to build for Zephyr when following the Zephyr RTOS example: Getting Started on Ubuntu 20.04 LTS:

$ make PRESET=ZEPHYR
# Using build PRESET "ZEPHYR" to set CONFIG and TARGET variables:
.    IOTC_BSP_PLATFORM: [zephyr] 
.    IOTC_BSP_TLS:      [mbedtls] 

# 
# Google IoT Core Embedded C Client Makefile 
#  Please see ./README.md for more information.
# 

.    CONFIG:          [memory_fs-tls_bsp]
.    TARGET:          [zephyr-static-debug]
.    COMPILER:        [cc] 

#  
# NOTE! Makefile executing 3rd Party TLS build:

Note: switching to 'zephyr-v1.14.0'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at cebe11544e release: Zephyr 1.14.0

Fixed this issue with: sudo apt-get install device-tree-compiler gperf. Perhaps Zephyr RTOS example: Getting Started can note this requirement.

Hi mike thanks for your feedback and how you fixed the issue!, i'll add the fix to the getting started guide.
