Xcode 編譯報錯等問題記錄

  1、IOS編譯時有時出現這樣的錯誤，要注意，錯誤不在Undefined for architecture i386，而是下面下劃線開頭的變量沒定義，此時須要導入libz到項目便可。

 

用zbar和zipachieve這個庫須要導入libz.dylib

二、在import第三方框架的時候（好比自定義的framework import pods），提示找不到文件，能夠檢查引用的頭部文件是否包含

找到 Header Search Paths 添加 $(SRCROOT)/../Pods/Headers/Public

 

三、

CocoaPods 0.38.2 is available.
To update use: `gem install cocoapods`

 

四、記錄錯誤：

提示，找不到AFDownloadRequestOperation,我嘗試着加上正確的地址，仍是不行，而後我在Architectures 添加了armv7s 神奇的編譯經過了，不知道爲何，誰能解釋下

而後 這樣不行的話在Build Settings-> Architechures 中 設置Build Active Architecture Only 設置爲NO

五、XCocde 7 發生一系列警告：

暫且在修改debug 模式的Debug Information Format 爲DWARF

 

六、

編譯的時候，出錯：Undefined symbols for architecture x86_64: "_llvm_gcda_emit_arcs", referenced from:

Undefined symbols for architecture x86_64: "_llvm_gcda_emit_arcs", referenced from: ___llvm_gcov_writeout in libPKRevealController.a(PKRevealController.o) ___llvm_gcov_writeout in libPKRevealController.a(PKAnimation.o) ___llvm_gcov_writeout in libPKRevealController.a(PKLayerAnimator.o) ___llvm_gcov_writeout in libPKRevealController.a(PKRevealControllerView.o) ___llvm_gcov_writeout in libPKRevealController.a(PKSequentialAnimation.o) ___llvm_gcov_writeout in libPKRevealController.a(UIViewController+PKRevealController.o) ___llvm_gcov_writeout in libPKRevealController.a(NSObject+PKBlocks.o) ...

解決方法："Instrument Program Flow" 改成Yes

七、

iOS項目中引入c++庫，編譯連接時報以下錯：

"std::string::_Rep::_M_destroy(std::allocator<char> const&)", referenced from:

"std::_List_node_base::hook(std::_List_node_base*)", referenced from:

"std::string::push_back(char)", referenced from:

"std::string::append(char const*, unsigned long)", referenced from:

"std::string::_Rep::_S_empty_rep_storage", referenced from:

很明顯，以上都是stdc++標準庫函數。

檢查Build Phases->Link Binary With Libraries 也包含了libstdc++.dylib庫，libstdc++.6.0.9.dylib
