所以我试图在Ubuntu上安装pHash库。我已经安装了运行此命令的所有必需软件包：
apt-get install libavformat-dev libmpg123-dev libsamplerate-dev libsndfile-dev cimg-dev libavcodec-dev ffmpeg libswscale-dev
然后我运行./configure，一切似乎都没问题，我得到了这个：

有些人可以帮我理解错误吗？
答案 0 :(得分：2)
看起来库pHash不再维护了。但是，如果使用库功能需要一些快速解决方案，则可以将其安装在兼容的Linux版本上。在这种情况下，可以设置一些虚拟服务器实例。
这个库对于Ubuntu 10.04来说太新了，因为它使用了2011-2013中引入的功能。
图书馆对于Ubuntu 14.04而言太旧了。
我能够在开箱即用的Ubuntu 12.10上构建库（也可以尝试12.04）。
方法文档：
# install libraries listed in the question
sudo apt-get install libavformat-dev libmpg123-dev libsamplerate-dev libsndfile-dev cimg-dev libavcodec-dev ffmpeg libswscale-dev
# some other libraries used by pHash can be also installed
sudo apt-get install libpng12-dev libjpeg62-dev libfftw3-dev
# configurate with custom install path
./configure --prefix=/home/username/dev/
make
make install
# build test application providing header and library path
g++ phash-test.cpp -I../include -L../lib -lpHash -o phash-test
# run test application providing library search path
LD_LIBRARY_PATH=/home/username/dev/lib:$LD_LIBRARY_PATH ./phash-test
答案 1 :(得分：0)
这是pHash中的一个错误，就像那样简单。例如，此警告
cimgffmpeg.cpp: In function 'int ReadFrames(VFInfo*, cimg_library::CImgList<unsigned char>*, unsigned int, unsigned int)':
cimgffmpeg.cpp:103:9: warning: 'AVFrame* avcodec_alloc_frame()' is deprecated (declared at /usr/include/libavcodec/avcodec.h:3195) [-Wdeprecated-declarations]
已经显示代码使用了不应使用的功能，这通常是在功能被其他功能替换时的情况。这通常是未维护的代码的标志。然后，你最终得到错误
cimgffmpeg.cpp:434:47: error: 'AVStream' has no member named 'r_frame_rate'
这意味着代码编写的AVStream类型的版本不是提供的版本。
您应该检查pHash更新，也许新版本已经修复了这些问题。另外，检查他们的错误跟踪系统，也许某人已根据错误修正或解决方法报告了此问题。
