我在ubuntu 14 64位版本上使用r 3.1.1。我安装了saga gis 2.1.2和rsaga 0.93-6。
到目前为止一切似乎都很好。
rsaga.env（）有效，我使用：
work_env <- rsaga.env(modules='/usr/lib/x86_64-linux-gnu/saga/')
因为在64位上，模块位于其他地方。
获取库也很有效：
> rsaga.get.libraries(path=work_env$modules)

[61] "ta_preprocessor" "ta_profiles" "ta_slope_stability" "tin_tools"

但当我试图获取模块或其他任何东西时，它会给出一个奇怪的错误：
> rsaga.get.modules("ta_preprocessor", env=work_env)
Error: tool
$ta_preprocessor
NULL
我发现rsaga官方并不支持更高版本的saga gis 2.1.0，但是当我尝试2.1.0时，我得到了另一个问题中描述的错误：https://gis.stackexchange.com/questions/109497/rsaga-saga-cmd-2-1-0-error-inconsistency
我该如何解决这个错误？
最佳答案
我通过从源代码（http://sourceforge.net/p/saga-gis/wiki/Compiling%20a%20Linux%20Unicode%20version/）编译saga gis 2.1.1来解决了这个问题。当我用rsaga执行一个工具时，我确实会得到另一个错误：“error:module”，但是执行似乎很好。
此外，萨加地理信息系统有时退出与分割断层…但不是经常。
