问题描述
我正在尝试在Centos机器上安装R'sf'.在gdal扩展问题(现在已通过源代码修复)之后，我得到了:
I am attempting to install R 'sf' on a Centos machine. After extended problems with gdal (now fixed by building from source), I now get:
Error: package or namespace load failed for ‘sf’ in dyn.load(file, DLLpath = DLLpath, ...):
无法加载共享对象'/home/my_user_name/R/x86_64-redhat-linux-gnu-库/3.4/sf/libs/sf.so':/home/my_user_name/R/x86_64-redhat-linux-gnu-library/3.4/sf/libs/sf.so:未定义的符号: ZN15OGRMultiSurface18CastToMultiPolygonEPS
unable to load shared object '/home/my_user_name/R/x86_64-redhat-linux-gnu- library/3.4/sf/libs/sf.so': /home/my_user_name/R/x86_64-redhat-linux-gnu-library/3.4/sf/libs/sf.so: undefined symbol: ZN15OGRMultiSurface18CastToMultiPolygonEPS
如何解决此错误?
推荐答案
因此，此问题显然是由于我手动安装的gdal无法正确链接到geos引起的.
So, this problem was apparently caused by my manual install of gdal not correctly linking to geos.
因此，我按照以下说明重新安装了gdal( https://trac.osgeo.org/gdal/wiki/BuildingOnUnix )，其中--with-geos = yes是./configure的标志.
So I just reinstalled gdal following these instructions (https://trac.osgeo.org/gdal/wiki/BuildingOnUnix) with --with-geos=yes as a flag to ./configure.
这解决了问题.
