libpngのUniversal Binaryを作成 - 途中
libpng-1.2.12のUniversal Binaryを作成する。
下記の３つの環境でlibpng-1.2.12をビルドしてみる。
下記のように３つの環境でlibpng-1.2.12をビルドする。
configure make sudo make install
fileコマンドでlibpng12.aを確認
Mac OS X 10.3.9 , Power Mac G3でビルドしたlibpng12.a
Macintosh:13.Projects kuru$ file lib_ppc/libpng12.a lib_ppc/libpng12.a: current ar archive random library
Mac OS X 10.5.8 , iMac (Intel)でビルドしたlibpng12.a
Macintosh:13.Projects kuru$ file lib_i386/libpng12.a lib_i386/libpng12.a: current ar archive random library
Mac OS X 10.6.1 , MacBook Pro (Intel)ビルドしたlibpng12.a
Macintosh:13.Projects kuru$ file lib_x86_64/libpng12.a lib_x86_64/libpng12.a: current ar archive random library
複数のライブラリを結合してUniversal Binaryにする
lipoコマンドで結合
Macintosh:13.Projects kuru$ lipo -create lib_x86_64/libpng12.a lib_ppc/libpng12.a lib_i386/libpng12.a -output lib/libpng12.a Macintosh:13.Projects kuru$ file lib/libpng12.a
fileコマンドで確認
lib/libpng12.a: Mach-O universal binary with 3 architectures lib/libpng12.a (for architecture x86_64): current ar archive random library lib/libpng12.a (for architecture ppc): current ar archive random library lib/libpng12.a (for architecture i386): current ar archive random library
ファイル自体はUniversal Binarynになっている。
ビルド
Universal Binaryになっているlibpng12.aをリンクしビルドしてみるが、
「ビルド設定のアクティブアーキテクチャのみをビルド」をOFFにするとリンクエラーが発生。
「ビルド設定のアクティブアーキテクチャのみをビルド」をOFFのビルド結果

実行
ビルドしたテストプログラムを実行してみると正常に動作したが、
試しに/usr/local/libの下のlibpng関連のファイルを削除して実行すると下記のエラーになった。
dyld: Library not loaded: /usr/local/lib/libpng12.0.dylib Referenced from: /Users/kuru/Documents/00_Atotok/11.atotok-dev/13.Projects/LibPngTest/build/Debug/./LibPngTest Reason: image not found Trace/BPT trap
このあとやること
- dylibを要求しないようにビルドする
- 「ビルド設定のアクティブアーキテクチャのみをビルド」をOFFでもビルドできるライブラリを作成する
- CFLAGSなど設定しconfigureとmakeでUniversal Binaryを作成
こんな感じか？
