Question

我已经通过Mac Ports安装了图形工具。几天前，我跑了

$ sudo port selfupdate
$ sudo port upgrade outdated

图形工具被重新编译（花了大约30个小时（！））现在，当我想在python中包含图形工具时，我得到以下错误：

Python 2.7.6 (default, Nov 22 2013, 13:39:24) 
[GCC 4.2.1 Compatible Apple Clang 4.1 ((tags/Apple/clang-421.11.66))] on darwin

我使用“port installed | grep boost”测试了boost包的版本和变体：结果：

  boost @1.49.0_0+python27
  boost @1.53.0_1+no_single+no_static+python27
  boost @1.53.0_2+no_single+no_static+python27
  boost @1.54.0_0+no_single+no_static+python27
  boost @1.55.0_1+no_single+no_static+python27
  boost @1.55.0_2+no_single+no_static+python27 (active)

对于图形工具本身，“port installed | grep graph-tool”的结果是：

  py27-graph-tool @2.2.25_0
  py27-graph-tool @2.2.29_0
  py27-graph-tool @2.2.29.1_0 (active)

当我检查错误消息中出现的库链接到哪些库时，这是结果：

$ otool -L /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/graph_tool/libgraph_tool_core.so
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/graph_tool/libgraph_tool_core.so:

    /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 56.0.0)

有人有想法吗？

谢谢，

问题已经解决。最新版本的图形工具假定为Mavericks（10.9。）并使用导致的libc ++ 麻烦，因为在MountainLion中，标准版本的MacPorts链接libstdc ++。结果符号被混淆了。

我安装了Mavericks，重新安装了所有端口，现在可以正常工作了！

这么久，

链接器麻烦与MacPorts安装图形工具
