libIlmImf.so.2 needed by解決方案

libIlmImf動態庫包含在libopenexr

root@c11cf9e6b275:/home/dong/color-detector/build# apt-cache search libopenexr
libopenexr-dev - development files for the OpenEXR image library
libopenexr22 - runtime files for the OpenEXR image library

解決

2）

apt-get update #更新安裝源
apt-get install libopenexr-dev #安裝依賴套件

安裝結果

root@c11cf9e6b275:/home/dong/color-detector/build# find / -name libIlmImf*   
/usr/lib/x86_64-linux-gnu/libIlmImf-2_2.so.22
/usr/lib/x86_64-linux-gnu/libIlmImfUtil-2_2.so.22
/usr/lib/x86_64-linux-gnu/libIlmImfUtil.a
/usr/lib/x86_64-linux-gnu/libIlmImf-2_2.so.22.0.0
/usr/lib/x86_64-linux-gnu/libIlmImf.so
/usr/lib/x86_64-linux-gnu/libIlmImf.a
/usr/lib/x86_64-linux-gnu/libIlmImfUtil.so
/usr/lib/x86_64-linux-gnu/libIlmImfUtil-2_2.so.22.0.0

注意：

1）網上提供了apt-cache search IlmImf搜索指令，實際上在新版本Ubuntu 5.4.0-6ubuntu1~16.04.10已經搜索不到任何的內容

2）error while loading shared libraries: libIlmImf-2_2.so.22: cannot open shared object file: No such file or directory，解決方案如上，更新系統之後，也會出現動態庫不一致的問題
