1 This directory contains files that make it possible to use system libraries. 2 3 For more info please read the following: 4 5 - https://fedoraproject.org/wiki/Packaging:No_Bundled_Libraries 6 - https://wiki.gentoo.org/wiki/Why_not_bundle_dependencies 7 - http://www.debian.org/doc/debian-policy/ch-source.html#s-embeddedfiles 8 9 For more Chromium-specific context please read 10 http://spot.livejournal.com/312320.html . 11 12 This directory is provided in the source tree to follow above guidelines. 13 It is a compromise solution which takes into account Chromium developers 14 who want to avoid the perceived burden of more conditional code in gyp, 15 and expectations of Open Source community, where using system-provided 16 libraries is the norm. 17 18 Usage: 19 20 1. remove_bundled_libraries.py <preserved-directories> 21 22 For example: remove_bundled_libraries.py third_party/mesa 23 24 The script scans sources looking for third_party directories. 25 Everything that is not explicitly preserved is removed (except for 26 gyp files), and the script fails if any directory passed on command 27 line does not exist (to ensure list is kept up to date). 28 29 This is intended to be used on sources extracted from a tarball, 30 not a repository. 31 32 NOTE: by default this will not remove anything (for safety). Pass 33 --do-remove flag to actually remove files. 34 35 2. replace_gyp_files.py <gyp-flags> 36 37 For example: replace_gyp_files.py -Duse_system_harfbuzz=1 38 39 The script ignores flags other than -D for convenience. This makes it 40 possible to have a variable e.g. ${myconf} with all the options, and 41 execute: 42 43 build/linux/unbundle/replace_gyp_files.py ${myconf} 44 build/gyp_chromium ${myconf} 45
