# Information about Coin instruction templates
|
||
|
|
|
||
|
|
## Build templates
|
||
|
|
|
||
|
|
* ``coin_qtbase_build_template_v2.yaml`` did not exist. The build instructions were directly embedded into
|
||
|
|
``module_config.yaml`` and did not support repos outside of qtbase, also no cross-compilation.
|
||
|
|
* ``coin_qtbase_build_template_v2`` introduced support for building other repos, and also enabled
|
||
|
|
build cross-compiling targets like ``Android`` and ``iOS``.
|
||
|
|
A bit later the template gained the ability to build ``qemu`` cross-compiling configurations.
|
||
|
|
The counterpart to qtbase to build other repositories is ``coin_module_build_template_v2``
|
||
|
|
|
||
|
|
## Test templates
|
||
|
|
|
||
|
|
* ``coin_module_test_template_v1`` did not exist. The test instructions were directly embedded into
|
||
|
|
``module_config.yaml`` and did not support repos outside of qtbase, also no cross-compilation.
|
||
|
|
* ``coin_module_test_template_v2`` introduced support for building tests for other repos, and made
|
||
|
|
sure not to build and run tests on cross-compiling configuration. A bit later the template gained
|
||
|
|
the ability to build and run tests for ``qemu`` cross-compiling configurations.
|
||
|
|
* ``coin_module_test_template_v3`` changed the run test instructions to not ignore the exit code
|
||
|
|
and thus enforce that tests pass in the CI.
|
||
|

# Environment variable description and usage
|
||
|
|
|
||
|
|
The following environment variables are used in Coin instructions when building Qt, tests, etc:
|
||
|
|
|
||
|
|
`CONFIGURE_ARGS` - contains platform-specific ``configure-style`` arguments
|
||
|
|
(e.g. `-shared`), that will be passed to a qtbase configure call
|
||
|
|
`CMAKE_ARGS` - contains platform-specific ``CMake-style`` arguments
|
||
|
|
(e.g. `-DOPENSSL_ROOT_DIR=Foo`) that will be passed to a qtbase
|
||
|
|
configure call
|
||
|
|
`NON_QTBASE_CONFIGURE_ARGS` - contains platform-specific ``configure-style`` arguments
|
||
|
|
that will be passed to a non-qtbase qt-configure-module call
|
||
|
|
`NON_QTBASE_CMAKE_ARGS` - contains platform-specific ``CMake-style`` arguments
|
||
|
|
that will be passed to a non-qtbase qt-configure-module call
|
||
|
|
`COMMON_CMAKE_ARGS` - platform-independent ``CMake-style`` args set in
|
||
|
|
`prepare_building_env.yaml` that apply to qtbase configurations
|
||
|
|
only.
|
||
|
|
`COMMON_NON_QTBASE_CMAKE_ARGS` - platform-independent ``CMake-style`` args set in
|
||
|
|
`prepare_building_env.yaml` that apply to
|
||
|
|
configuration of repos other than qtbase
|
||
|
|
`COMMON_TEST_CMAKE_ARGS` - platform-independent ``CMake-style`` args set in
|
||
|
|
`prepare_building_env.yaml` that apply to configuration of
|
||
|
|
all standalone tests
|
||
|
|
|
||
|
|
All of the above apply to host builds only.
|
||
|
|
|
||
|
|
There is a a set of environment variables that apply to target builds when cross-compiling which
|
||
|
|
mirror the ones above. They are:
|
||
|
|
|
||
|
|
`TARGET_CONFIGURE_ARGS`
|
||
|
|
`TARGET_CMAKE_ARGS`
|
||
|
|
`NON_QTBASE_TARGET_CONFIGURE_ARGS`
|
||
|
|
`NON_QTBASE_TARGET_CMAKE_ARGS`
|
||
|
|
|
||
|
|
`COMMON_TARGET_CMAKE_ARGS`
|
||
|
|
`COMMON_NON_QTBASE_TARGET_CMAKE_ARGS`
|
||
|
|
`COMMON_TARGET_TEST_CMAKE_ARGS`
|
||
|
|
|
||
|
|
Currently, there are no common ``configure-style`` variables for configuring
|
||
|
|
repos or tests, only ``CMake-style` ones.
|
||
|
|
|
||
|
|
|
||
|
|
`COIN_CMAKE_ARGS` contains the final set of cmake args that is passed to
|
||
|
|
`configure` / `qt-configure-module`, it is built up from the variables above + any additional values added
|
||
|
|
by custom instructions, like specification of `CMAKE_INSTALL_PREFIX` etc.
|
||
|
|
|
||
|
|
`INSTALL_DIR_SUFFIX` is used to append either `/host` or `/target` suffixes to install paths in
|
||
|
|
instructions when cross-building.
|
||
|
|
|
||
|
|
`CONFIGURE_EXECUTABLE` contains a platform-specific path to `configure` / `qt-configure-module`
|
||
|
|
or `cmake`/ `qt-cmake` depending on whether `UseConfigure` feature is enabled.
|
||
|
|
|
||
|
|
`CONFIGURE_ENV_PREFIX` contains the value of either `ENV_PREFIX` or `TARGET_ENV_PREFIX` depending on
|
||
|
|
whether it's a cross-build configure call. The values are used when configuring and building, to ensure
|
||
|
|
that things like compilers are found correctly.
|
||
|
|
|
||
|
|
We use `unixPathSeparators` to pass an install prefix with forward slashes even on Windows,
|
||
|
|
to avoid escaping issues when using configure.
