caffe安装:opencv libpng16.so.16链接问题 [英] caffe installation : opencv libpng16.so.16 linkage issues
问题描述
我正在尝试在Ubuntu 14.04计算机上使用python接口编译caffe.
I am trying to compile caffe with python interface on an Ubuntu 14.04 machine.
我已经用conda install opencv安装了Anaconda和opencv.我还安装了咖啡中规定的所有要求，并更改了makefile.config中的注释框，以便PYTHON_LIB和PYTHON_INCLUDE指向Anaconda发行版.
I have installed Anaconda and opencv with conda install opencv. I have also installed all the requirement stipulated in the coffee and changed the commentary blocks in makefile.config so that PYTHON_LIB and PYTHON_INCLUDE point towards Anaconda distributions.
当我呼叫make all时，将发出以下命令:
When I am calling make all, the following command is issued:
g++ .build_release/tools/caffe.o -o .build_release/tools/caffe.bin -pthread

但是，它会因以下错误而停止:
However, it is stopped by the following set of errors:

Following the advice from this question: Caffe install on ubuntu for anaconda with python 2.7 fails with libpng16.so.16 not found, I tired running the ldd /home/andrei/anaconda/lib/libopencv_highgui, and obtained the following output:

然后我继续将所有必需的目录添加到make.config文件的INCLUDE_DIRS和LIBRARY_DIRS中(因此，在上面的g++调用中还有其他的-I和-L)，包括显式链接anaconda库中已经存在的libpng16.so.16.但是，这尚未解决问题.我还尝试将文件添加到$LD_LIBRARY_PATH和$LD_RUN_PATH，但是没有任何效果.
I then proceeded to add all the required directories into the INCLUDE_DIRS and LIBRARY_DIRS of the make.config file (hence additional -I and -L in the g++ call above), including the explicit link to libpng16.so.16 already present in anaconda libraries. This have however not resolved the issue. I also tried adding the file to $LD_LIBRARY_PATH and $LD_RUN_PATH, but without any effect.
可能是什么问题，我该如何解决?
What might the problem be and how could I resolve it?
推荐答案
我遇到了同样的问题.我发现它与 https://github.com/BVLC/caffe/issues/2007 类似，并且我解决了通过
I came across the same problem. I found it similar to https://github.com/BVLC/caffe/issues/2007, and I solved it by
cd /usr/lib/x86_64-linux-gnu
sudo ln -s ~/anaconda/lib/libpng16.so.16 libpng16.so.16
sudo ldconfig
