Xcode中的鏈接時優化問題

Question

我應該在Xcode中爲「發佈調試符號」打開發布配置嗎？當它和「鏈接時優化」被打開的Xcode顯示警告：

GenerateDSYMFile build/Release/cocoa_tutorial5.app.dSYM build/Release/cocoa_tutorial5.app/Contents/MacOS/cocoa_tutorial5 cd /Users/ariel/Documents/spacesimulator.net/cocoa_tutorial5 /Developer/usr/bin/dsymutil /Users/ariel/Documents/spacesimulator.net/cocoa_tutorial5/build/Release/cocoa_tutorial5.app/Contents/MacOS/cocoa_tutorial5 -o /Users/ariel/Documents/spacesimulator.net/cocoa_tutorial5/build/Release/cocoa_tutorial5.app.dSYM

Answer 1

鏈接時優化和調試信息目前沒有一起工作（如的Xcode 3.2，調試符號之前，他們甚至剝奪到達最終的可執行文件）在LLVM中。

修訂

鏈接時優化和調試信息（DWARF或矮跟的dSYM文件）在Xcode 5或更高版本一起工作。
