# This script will update Skia's dependenciess as necessary and run
|
|
# gyp if needed.
|
|
|
|
# Example usage (assumes Posix-standard shell, git installed):
|
|
#
|
|
# git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
|
|
# export PATH="${PWD}/depot_tools:${PATH}"
|
|
# git clone https://skia.googlesource.com/skia
|
|
# cd skia
|
|
# bin/sync-and-gyp && ninja -C out/Debug
|
|
# out/Debug/dm
|
|
#
|
|
# Once changes are made to DEPS or gyp/ or the source, recompile Skia with:
|
|
#
|
|
# ${skiadir}/bin/sync-and-gyp && ninja -C ${skiadir}/out/Debug
