python in mac os x error未定義符號：「_PyImport_Import」

Question

在mac os x（10.6.8）中構建SUMO（模擬城市MObility http://sumo.sf.net/）時發生以下錯誤。我不認爲這是特定於SUMO，而是在mac相關的問題python安裝，所以我張貼在這裏。僅供參考，Python版本在這裏是2.7.1。

有關如何解決此問題的任何想法？

Answer 1

我發現了SUMO網站（here）鏈接：

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 

它的工作對我來說，突破這個編譯錯誤。儘管這些行與MacPort一起工作。
