Question

在mac os x（10.6.8）中构建SUMO（模拟城市移动性http://sumo.sf.net/）时发生以下错误。我不认为这是特定于SUMO，而是mac相关问题中的python安装，所以我在这里发帖。仅供参考，这里的python版本是2.7.1。

关于如何解决这个问题的任何想法？

我在SUMO的网站（here）上找到了一个链接：

 export CPPFLAGS="$CPPFLAGS -I/opt/local/include"
 export LDFLAGS="$LDFLAGS -L/opt/local/lib -lpython2.7"
./configure --with-fox=/opt/local --with-proj-gdal=/opt/local --with-xerces=/opt/local --prefix=/opt/sumo --with-python

我可以通过这个编译错误。这些行正在与MacPort一起使用。

mac os in mac os x error未定义的符号：“_ PyImport_Import”
