Linux 在Ubuntu中哪里可以找到libopenexr.so？

我想构建一些依赖于libopenexr库的代码示例

我发现了这两个包：

wiesniak@wiesniak-Precision-M4800:~/OpenGLSB5E_build$ apt-cache search openexr
...
libopenexr-dev - development files for the OpenEXR image library
libopenexr6 - runtime files for the OpenEXR image library
...

我尝试安装它们，但它们已安装：

wiesniak@wiesniak-Precision-M4800:~/OpenGLSB5E_build$ sudo apt-get install libopenexr6 libopenexr-dev
...
libopenexr-dev is already the newest version.
libopenexr6 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

我在/usr/include中看到了include文件，但是找不到相应的库。所以我不能链接这个项目。 我做了几次尝试，比如：

wiesniak@wiesniak-Precision-M4800:~/OpenGLSB5E_build$ ldconfig -p |grep exr
wiesniak@wiesniak-Precision-M4800:~/OpenGLSB5E_build$ 

但系统中似乎没有

知道它在哪里吗？ 我还应该做些什么？ 我怎样才能找到它？

好的，我找到了答案

我假设库名称类似于：libopenexr*.so，但我错了

libopenexr包提供的库的正确名称是libIlmImf

** IlmImf - a library that reads and writes OpenEXR images.**

顺便说一句，我永远不会理解为什么人们会给出这样的名字，甚至连发音都不可能，甚至连与包裹名称无关的名字都不提。

试试：

结果是：

gstreamer1.0-plugins-bad:amd64: /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstopenexr.so

OpenEXR基于以下文件的低级操作工具：

• 图像格式（imf）
• 由Industrial Light&Magic（ilm）创建

所以库（lib）被命名为libIlmImf

名称正在更改，在OpenEXR 3.x中，库将被删除
