Linker script generator produces build/esp32/esp32.common.ld from components/esp32/ld/esp32.common.ld.in This works fine until IDF is downgraded to V3.1 which uses components/esp32/ld/esp32.common.ld and doesn't track build/esp32/esp32.common.ld at all. At this point, the linker runs in the build/esp32 directory and "-T esp32.common.ld" picks up the linker script generated .ld file, which causes mis-builds. As reported on forums: https://esp32.com/viewtopic.php?f=13&t=9684&p=40105

# Test the build system for basic consistency
|
|
#
|
|
# A bash script that tests some likely make failure scenarios in a row
|
|
#
|
|
# Assumes PWD is an out-of-tree build directory, and will create a
|
|
# subdirectory inside it to run build tests in.
|
|
#
|
|
# Environment variables:
|
|
# IDF_PATH - must be set
|
|
# ESP_IDF_TEMPLATE_GIT - Can override git clone source for template app. Otherwise github.
|
|
# NOCLEANUP - Set to '1' if you want the script to leave its temporary directory when done, for post-mortem.
|
|
#
|
|
#
|
|
# Internals:
|
|
# * The tests run in sequence & the system keeps track of all failures to print at the end.
|
|
# * BUILD directory is set to default BUILD_DIR_BASE
|
|
# * The "print_status" function both prints a status line to the log and keeps track of which test is running.
|
|
# * Calling the "failure" function prints a failure message to the log and also adds to the list of failures to print at the end.
|
|
# * The function "assert_built" tests for a file relative to the BUILD directory.
|
|
# * The function "take_build_snapshot" can be paired with the functions "assert_rebuilt" and "assert_not_rebuilt" to compare file timestamps and verify if they were rebuilt or not since the snapshot was taken.
|
|
#
|
|
# To add a new test case, add it to the end of the run_tests function. Note that not all test cases do comprehensive cleanup
|
|
# (although very invasive ones like appending CRLFs to all files take a copy of the esp-idf tree), however the clean_build_dir
|
|
# function can be used to force-delete all files from the build output directory.
|
|

# Set up some variables

# override ESP_IDF_TEMPLATE_GIT to point to a local dir if you're testing and want fast iterations
