Defining CMake variables from the command-line or from another CMake project,
such as `-DCMAKE_C_FLAGS= -DCMAKE_CXX_FLAGS=`, caused a link failure as ESP
CMake was unable to set its proper compilation flags.
Additional CMake compiler flags can now be provided by another project.
* Closes https://github.com/espressif/esp-idf/issues/7507
Some tests check if certain files are rebuilt when source files are
'touch'ed. With ccache, 'touch'ing source files doesn't cause a
rebuild, hence the test fails. In case IDF_CCACHE_ENABLE was set in
the environment, unset it before starting the tests.
Replaced hyphens with underscores in examples
project definition for all examples which had
hyphens in their project name. dpp-enrollee is
an exceptions because the name matches the
project directory name while the project
directory also contains hyphens.
This feature was added when we thought that target components might be
added out of IDF tree. That never became possible, and with recent
changes in IDF architecture it is unlikely that this feature will be
necessary any time soon. Remove it, simplifying the code.
Add docs subcommand with options:
--no-browser - Prints url for current documentation instead of opens browser with documentation
--language - Select documentation language
--starting-page - Choice section of documentation to open
--version - Choice version of esp-idf
--target - Choice model of your target
Currently IDF_VERSION_* variables are not available to the component
CMakeLists.txt files at the requirements expansion stage. This makes
it harder to write component CMakeLists files compatible with
different IDF versions.
Include version.cmake from the requirements expansion script, add a
build system test.
Also add some explanation about configuring the project in the README
Previously with the default build-esp32.sh script, the build directory was
deleted and recreated so the project would always be built with default config.
idf.py bootloader runs very quickly on some build servers, so when
sdkconfig is modified, the next idf.py invocation doesn't pick up the
timestamp difference. Add some delays to make sure the change is
noticed.
This solves the issue that target is changed to the default one after
idf.py fullclean.
Also allow setting the default target using sdkconfig.defaults, e.g.
CONFIG_IDF_TARGET="esp32s2"
Closes IDF-1040
