Xcode中的wxWidgets項目中的未定義符號

Question

我想在Mac OS X 10.8.3上使用wxWidgets-2.9.4在Xcode中配置項目。我使用以下選項配置wxWidgets：

./configure --enable-debug --disable-shared --enable-unicode --with-osx_cocoa --enable-monolithic 

然後成功編譯庫。所有演示工作正常。

我使用wx-config獲取的標誌配置了我的項目。特別是：

./wx-config --libs 
-L/wxWidgets/wxWidgets-2.9.4/build-release/lib -framework IOKit -framework Carbon - framework Cocoa -framework AudioToolbox -framework System -framework OpenGL /wxWidgets/wxWidgets-2.9.4/build-release/lib/libwx_osx_cocoau-2.9.a -framework WebKit -lwxregexu-2.9 -lwxtiff-2.9 -lwxjpeg-2.9 -lwxpng-2.9 -lz -lpthread 

./wx-config --cxxflags 
-I/wxWidgets/wxWidgets-2.9.4/build-release/lib/wx/include/osx_cocoa-unicode-static-2.9 - I/wxWidgets/wxWidgets-2.9.4/include -D_FILE_OFFSET_BITS=64 -D__WXMAC__ -D__WXOSX__ -D__WXOSX_COCOA__ 

當我嘗試建立我的項目，我得到很多的未定義符號：

以及更多。

該項目工作正常，如果我使用wxMac-2.8.12，但我有一些圖形問題，所以我想嘗試新版本。

感謝您的任何幫助。 平安夜

您可能只爲x86構建了wxWidgets。無論如何，您絕對是爲單一架構而構建的，而您的Xcode項目可能是爲x86和x86_64構建的。

如果您確實需要64位版本的應用程序，則應該使用--enable-universal_binary=x86,x86_64選項重新配置wxWidgets。但我建議僅在32位中構建Xcode項目（即僅適用於x86），至少在開發期間。
