# Your build script should simply source this script, optionally override any build hooks and then invoke `build`.
|
|
# The build product should be available under `build-<platform>~/out`, under the library path.

# Hook lifecycle:
|
|
# - build
|
|
# - initialize
|
|
# - needs
|
|
# - clean & exit (only if script was ran with "clean" argument)
|
|
# - prepare
|
|
# - clean
|
|
# - config
|
|
# - target
|
|
# - prepare
|
|
# - configure
|
|
# - build
|
|
# - finalize
|
|
# - merge
|
|
# - clean
|
|

|
|
# You can override any of these hooks to provide a custom implementation or call their underscore variant to delegate to the default implementation.

# For example:
|
|
# target_prepare() { make -s distclean; }

# target_configure() { _target_configure "$@" --enable-minimal; }
