我想在Postgis中安装SFCGAL支持，所以我尝试从源代码安装它。
Ubuntu 13.04，PostgreSQL是从软件包安装的。
PostGIS现已配置为i686-pc-linux-gnu

我总是遇到这个错误如果我安装它--without-raster或--with-raster：
./configure --with-raster --with-topology --with-geosconfig=/etc/geos-3.4.2/tools/geos-config --with-sfcgal=/usr/include/SFCGAL --with-projdir=/etc/proj-4.8.0
