量子GIS（qgis）是一個開源的GIS軟件。 qgis的功能可以通過用python或C++編寫的插件來擴展。這個問題與基於C++的DTClassifier有關。 DTClassifier使自動化柵格地圖分類成爲可能，例如自動化遠程感測數據上的森林分類。編譯量子gis dtclassifier C++插件
我要安裝QGIS 1.8.0（Ubuntu的12.04 64位）的插件，其是通過將已編譯的Linux DTClassifier plugin file做成
/usr/lib/qgis/plugins
然而，這是一個32位的二進制сompiled在使用OpenCV 2.3.1的32位Slackware 13.1下，而我的操作系統是Ubuntu 12.04 64位。將文件放入
/usr/lib/qgis/plugins
不被qgis識別。也許是因爲我有64位操作系統和OpenCV 2.4.1。所以我試圖編譯提供的源代碼，但沒有這樣做。 任何人都可以爲我提供如何編譯插件或提供已編譯文件的幫助？
這是我迄今完成：
我安裝了OpenCV的2.4.1，以及Qt4，並下載源DTClassifier
svn co http://svn.gis-lab.info/dtclassifier/trunk dtclassifier
此源被放入QGIS-1.8 .0來源。然後cmake運行CMakeLists.txt：
我發現這(forum message)這是指向Ubuntu 11.04的64位版本，但我無法使它的工作。
的是我迄今爲止嘗試過的細節可以發現如下：
