| |
| This directory is provided in the source tree to follow above guidelines. |
| It is a compromise solution which takes into account Chromium developers |
| who want to avoid the perceived burden of more conditional code in gyp, |
| and expectations of Open Source community, where using system-provided |
| libraries is the norm. |
| |
| Usage: |
| |
| 1. remove_bundled_libraries.py <preserved-directories> |
| |
| For example: remove_bundled_libraries.py third_party/mesa |
| |
| The script scans sources looking for third_party directories. |
| Everything that is not explicitly preserved is removed (except for |
| gyp files), and the script fails if any directory passed on command |
| line does not exist (to ensure list is kept up to date). |
| |
| This is intended to be used on sources extracted from a tarball, |
| not a repository. |
| |
| NOTE: by default this will not remove anything (for safety). Pass |
| --do-remove flag to actually remove files. |
| |
| 2. replace_gyp_files.py <gyp-flags> |
| |
| For example: replace_gyp_files.py -Duse_system_harfbuzz=1 |
| |
| The script ignores flags other than -D for convenience. This makes it |
| possible to have a variable e.g. ${myconf} with all the options, and |
| execute: |
| |
| build/linux/unbundle/replace_gyp_files.py ${myconf} |
| build/gyp_chromium ${myconf} |
