collect2: error: ld returned 1 exit status 。。。很長一串問題
對於這個問題找了N久都沒有找到答案，在caffe的issue中看到有人有同樣的問題，但並沒有得到答案，后來在另一個問題中看到了一個方法https://github.com/BVLC/caffe/issues/2348，
cd caffe cp Makefile.config.example Makefile.config and change setting in Makefile.config mkdir build cd build cmake .. ./configure (??not sure??) make all
執行一遍后發現有戲啊，可是又有一個新的關於opencv_imgcodecs的問題，同樣在剛才的鏈接中的方法
add "opencv_imgcodecs" in Makefile.(LIBRARIES += glog gflags protobuf leveldb snappy \
lmdb boost_system hdf5_hl hdf5 m \
opencv_core opencv_highgui opencv_imgproc opencv_imgcodecs)
就是在makefile的“LIBRARIES +=”中添加一個“opencv_imgcodecs”,make clean，再make all這樣剛才的問題就沒有了
這樣就可以了？？？結果又出了一個新的問題，/usr/lib/libopencv_highgui.so.2.4: undefined reference to TIFFRGBAImageOK@LIBTIFF_4.0' 1>
網上說是opencv編譯的問題，於是就重新編譯opencv，這次編譯cmake加上一個參數：
-D BUILD_TIFF=ON
於是又屁顛屁顛的開始編譯了，這一次已經有了報錯的心里准備了，果然新的問題來了，//usr/lib/x86_64-linux-gnu/libsoxr.so.0:對‘GOMP_parallel@GOMP_4.0’未定義的，
對於這個問題我以為百度一下就能解決，可事實證明我還是too young too simple，這個問題找了很久都沒找到答案，但是有個發現，就是稍微沾邊的解釋里都有anaconda，突然醒悟，我現在遭的罪不都是安裝了anaconda后造成的么，搞不好是anaconda與系統兼容造成的，於是我決定anaconda
零時屏蔽了再來編譯opencv試試，屏蔽的具體方法是在
sudo gedit ~/.bashrc 在下面這兩句話前面加上“#”注釋掉 #export PATH="/home/ks/anaconda2/bin:$PATH" #export LD_LIBRARY_PATH="/home/ks/anaconda2/lib:$LD_LIBRARY_PATH"
然后再次來編譯opencv，奇跡出現啦，經過漫長的等待，opencv終於編譯完成啦，現在回頭想想，caffe之所以編譯報那么多錯肯定也是由anaconda造成的,但是屏蔽anaconda后用以前的方法直接編譯caffe還是會報很多錯，不過用上面提到的cmake的方式進行編譯就順利的完成了。
總結一下經驗就是：可能是anaconda自帶的編譯環境的版本有問題，所以今后就算想用anaconda，也要先把caffe和opencv編譯好后再裝anaconda！
