cocos2d-x-3.14 の external を bitcode 有効にしてビルド
環境
- Mac OS X 10.12.2 (英語)
- Xcode 8.2.1
手順
-
cocos2d-x-3rd-party-libs-src を git clone
$ git clone https://github.com/cocos2d/cocos2d-x-3rd-party-libs-src.git Cloning into 'cocos2d-x-3rd-party-libs-src'... remote: Counting objects: 2385, done. remote: Total 2385 (delta 0), reused 0 (delta 0), pack-reused 2385 Receiving objects: 100% (2385/2385), 443.39 KiB | 138.00 KiB/s, done. Resolving deltas: 100% (1285/1285), done. $ cd cocos2d-x-3rd-party-libs-src -
cocos2d-x-3.14 用に git checkout
-
cocos2d-x-3.14 の v3-deps-16 リリース (2016-12-15) は、日付からコミット b8e116d (2016-11-21) であると仮定
$ git checkout b8e116d Note: checking out 'b8e116d'. You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example: git checkout -b <new-branch-name> HEAD is now at b8e116d... Merge pull request #128 from minggo/v3

-
README.md に従ってビルド用のツールをインストール
$ brew update $ brew install git $ brew install cmake $ brew install autoconf $ brew install automake $ brew install libtool $ brew list --versions autoconf 2.69 automake 1.15 cmake 3.7.1 git 2.11.0 libtool 2.4.6_1 -
README.md に従って bitcode を有効に
-
build/ios.ini の
cfg_build_bitcode=を
cfg_build_bitcode="-fembed-bitcode"に変更
-
-
ダウンロードできない URL を修正
-
http://zlib.net/zlib-1.2.8.tar.gz が
404 Not Foundになってるので-
contrib/src/zlib/rules.mak の
ZLIB_URL := http://zlib.net/zlib-$(ZLIB_VERSION).tar.gzを
ZLIB_URL := http://zlib.net/fossils/zlib-$(ZLIB_VERSION).tar.gzに変更
-
-
https://chipmunk-physics.net/release/Chipmunk-7.x/Chipmunk-7.0.1.tgz が SSL 証明書エラーを起こすので
-
contrib/src/chipmunk/rules.mak の
CHIPMUNK_URL := https://chipmunk-physics.net/release/Chipmunk-7.x/Chipmunk-$(CHIPMUNK_VERSION).tgzを
CHIPMUNK_URL := http://chipmunk-physics.net/release/Chipmunk-7.x/Chipmunk-$(CHIPMUNK_VERSION).tgzに変更
-
- (2017-04) http://heanet.dl.sourceforge.net/sourceforge/freetype/freetype2/2.5.5/freetype-2.5.5.tar.gz が
404 Not Foundになってるので-
contrib/src/freetype/rules.mak の
FREETYPE2_URL := $(SF)/freetype/freetype2/$(FREETYPE2_VERSION)/freetype-$(FREETYPE2_VERSION).tar.gzを
FREETYPE2_URL := http://download.savannah.gnu.org/releases/freetype/freetype-$(FREETYPE2_VERSION).tar.gzに変更
-
- (2017-04) http://heanet.dl.sourceforge.net/sourceforge/libpng/libpng16/1.6.16/libpng-1.6.16.tar.xz が
404 Not Foundになってるので-
contrib/src/main.mak の

iOS 用に release ビルド
$ cd build $ ./build.sh -p=ios --libs=chipmunk,curl,freetype,jpeg,lua,luajit,png,tiff,webp,websockets --arch=all --mode=release -
--libs=allだと rapidjson でエラーが起きるcreate folder for library with specify arch. ios/rapidjson/prebuilt/x86_64 cp: .../cocos2d-x-3rd-party-libs-src/build/../contrib/install-ios/x86_64/lib/librapidjson.a: No such file or directory Copying needed heder files cleaning up yes create fat library librapidjson for error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: no input files specified fatal error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: Usage: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo [input_file] ...

1. コミット b8e116d の contrib/src に存在しているのに cocos2d-x-3.14/external に存在しないもののリスト
1. angle
2. glew
3. iconv
4. ogg
5. openssl
2. 逆に cocos2d-x-3.14/external に存在して contrib/src に存在しないもののリスト
1. Box2D
2. ConvertUTF
3. bullet
4. clipper
5. edtaa3func
6. flatbuffers
8. poly2tri
9. rapidxml
9. recast
10. spidermonkey
11. tinyxml2
12. unzip
13. xxhash
14. xxtea
15. (プラットフォーム固有の *-specific は除く）
3. 両者に共通して存在するもののリスト
1. chipmunk
2. curl
3. freetype (freetype2 in external)
4. glfw (glfw3 in external)
5. jpeg
6. lua (lua/lua in external)
7. luajit (lua/luajit in external)
7. png
7. rapidjson (json in external)
8. sqlite (sqlite3 in external)
9. tiff
10. webp
11. websockets
12. zlib
4. 両者に共通するもの全てを ```--libs``` に指定すると、以下のエラーが出る
Invalid library names! Only png zlib lua luajit websockets curl freetype jpeg tiff webp chipmunk openssl rapidjson is acceptable!
5. 従って glfw と sqlite はビルドしない
6. rapidjson も上記のエラーが出るのでビルドしない
7. external/zlib/prebuilt に ios ディレクトリが存在しないので zlib もビルドしない
8. cocos2d-x-3.14/external/curl/prebuilt/ios に libssl.a が存在するが
1. openssl をビルド指定しなくても libssl.a は curl 配下でビルドされる
2. 同様に、ビルド指定しなくても libcrypto.a と libz.a も curl 配下でビルドされる
-
build の最初の方で以下の警告が出るが
SDKROOT not specified, assuming /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS10.2.sdk-
SDKROOT を設定すると以下のエラーが出てしまったので指定しない
CMake Error at /usr/local/Cellar/cmake/3.7.1/share/cmake/Modules/CMakeTestCCompiler.cmake:51 (message): The C compiler "/usr/bin/xcrun" is not able to compile a simple test program.

- diff で差異が見つかった
- external のバージョンは cocos2d-x-3rd-party-libs-bin 固有のコードで、本家には存在しないし chipmunk/cocos2d.patch にも存在しない
- cocos2d-x-3rd-party-libs-bin は cocos2d-x-3rd-party-libs-src からビルドしているものではないのかも・・・
-
#ifdef WIN32で囲まれた部分での差異なのでコンパイル結果には影響ないはず- この差異はとりあえず無視
