Question

我一直在努力为python安装matplotlib库几天了。我有freetype，XCode，X11和绑定的绑定，但现在当我尝试安装matplotlib时，我收到以下错误：

building 'matplotlib.backends._macosx' extension

gcc-4.2 -fno-strict-aliasing -fno-common -dynamic -arch i386 -arch x86_64 -g -O2 
-DNDEBUG -g -O3 -DPY_ARRAY_UNIQUE_SYMBOL=MPL_matplotlib_backends__macosx_ARRAY_API 
-DPYCXX_ISO_CPP_LIB=1 -I/Library/Frameworks/Python.framework/Versions/2.7/lib

-c src/_macosx.m 
-o build/temp.macosx-10.6-intel-2.7/src/_macosx.o

In file included from /System/Library/Frameworks/Foundation.framework/Headers/Foundation.h:161,
     from /System/Library/Frameworks/Cocoa.framework/Headers/Cocoa.h:12,
     from src/_macosx.m:1:
     /System/Library/Frameworks/Foundation.framework/Headers/NSUserNotification.h:16:
     error: expected ‘,’ or ‘}’ before ‘__attribute__’

这附带了一些关于弃用的numpy API的警告，但这些似乎没有引起任何问题。谁能告诉我这里的问题是什么？

为了记录，我正在使用gcc-4.2。

Answer 1

只需编辑/System/Library/Frameworks/Foundation.framework/Headers/NSUserNotification.h：

sudo nano /System/Library/Frameworks/Foundation.framework/Headers/NSUserNotification.h

更改第16行：

NSUserNotificationActivationTypeReplied NS_AVAILABLE(10_9, NA) = 3

为：

NSUserNotificationActivationTypeReplied /* NS_AVAILABLE(10_9, NA) */ = 3

然后重试安装matplotlib：

sudo pip install matplotlib

这为我解决了！

检查which -a gcc-4.2的输出。如果它/usr/bin/gcc-4.2你没有使用Xcode提供的gcc。要解决此问题，请运行前缀为CC=/usr/bin/gcc的构建命令（或pip等）。这应该可以解决这个错误。
