【问题描述】：

当我尝试在我的数据库上启用 PostGis 扩展时，我收到以下信息：

postgis=# CREATE EXTENSION postgis;
ERROR:  could not load library "/usr/pgsql-9.3/lib/rtpostgis-2.1.so": libhdf5.so.6: cannot open shared object file: No such file or directory

我使用 find -name 来查找文件：

[root@digihaul3-pc /]# find -name rtpostgis-2.1.so
./usr/pgsql-9.3/lib/rtpostgis-2.1.so

[root@digihaul3-pc /]# find -name libhdf5.so.6
./usr/lib64/mpich2/lib/libhdf5.so.6
./usr/pgsql-9.3/lib/libhdf5.so.6
./usr/lib/mpich2/lib/libhdf5.so.6

【问题讨论】：

您运行的是哪个操作系统？您可能会找到答案 here - 但如果没有更多详细信息，我无法提供进一步的建议。
CentOS，Ruby on rails 3，ruby 1.9.3
很不幸，我猜你已经找到了我见过的大多数其他帮助，即在 CentOS 中安装似乎存在问题。但是，this looks most useful 和 this may also help, although not about CentOS。抱歉，我帮不上忙，因为这样的问题，我很少使用 CentOS...

感谢 Thinking Monkey @post

它适用于 fordora 15。但我尝试了其他所有方法，这实际上解决了我的问题并允许我安装 postgis 扩展。安装时间不长。

Thinking Monkeys 帖子：

Checked for whether /etc/ld.so.conf has a reference to the path /usr/lib64/mpich2/lib.

by doing  ldconfig -p | grep libhdf5.

Which did not output anything.

On checking that /etc/ld.so.conf had  include ld.so.conf.d/*.conf.

Checked for the files in directory ld.so.conf.d. One of the conf file in include ld.so.conf.d was /etc/ld.so.conf.d/atlas-x8664.conf which contained /usr/lib64/atlas.

So I,

    created a file called gdal.conf in the directory ld.so.conf.d.
    Added the string /usr/lib64/mpich2/lib to the file.
    Ran ldconfig.
    Now, ldconfig -p | grep libhdf5 had the paths to llibhdf5 files.
    After doing the above, postgis raster support installation went smoothly.

它在寻找 .6 但我的 libhdf5 文件都是 .7
