Purging and rebuilding ldconfig cache?
提问by eminemence
I am trying to purge the ldconfig cache of links to libraries to link against. I have a local folder where newly built libraries are placed. I want to update the ldconfig cache to point to these newly built libs.
我正在尝试清除指向要链接的库的链接的 ldconfig 缓存。我有一个本地文件夹，其中放置了新建的库。我想更新 ldconfig 缓存以指向这些新构建的库。
I have tried using the ldconfig -c command, giving it my own .conf file. I also tried replacing the /etc/ld.so.conf file to point to the new path of libs. But even after doing this, when I check the cache using the ldconfig -p command , it is still showing the old libs.
我试过使用 ldconfig -c 命令，给它我自己的 .conf 文件。我还尝试替换 /etc/ld.so.conf 文件以指向 libs 的新路径。但即使这样做之后，当我使用 ldconfig -p 命令检查缓存时，它仍然显示旧的库。
Hence how to purge and rebuild the ldconfig cache? Just to add : I am on Ubuntu 13.10.
因此如何清除和重建 ldconfig 缓存？补充一点：我在 Ubuntu 13.10 上。

Rebuild cache
重建缓存
Open the /etc/ld.so.confas sudo and add a new line with the library directory. In this case, we add /usr/local/lib.
Rerun ldconfig to rebuild the cache:
打开/etc/ld.so.confas sudo 并在库目录中添加一个新行。在这种情况下，我们添加/usr/local/lib. 重新运行 ldconfig 以重建缓存：
$ sudo ldconfig
This worked for me.
这对我有用。
