Ubuntu16.04下 caffe make all時報錯：make: *** [.build_release/lib/libcaffe.so] Error 1

Ubuntu16.04下 caffe make all時報錯：

/usr/bin/ld: cannot find -lhdf5_hl

/usr/bin/ld: cannot find -lhdf5

collect2: error: ld returned 1 exit status

Makefile:502: recipe for target ‘.build_release/lib/libcaffe.so’ failed

make: * [.build_release/lib/libcaffe.so] Error 1

解決辦法如下：

1）首先檢查自己的hdf5是否安裝成功：sudo apt-get install libhdf5-serial-dev，如果顯示libhdf5-serial-dev is already the newest version則證明安裝成功，跳轉下一步；

2）嘗試修改Makefile.config檔案下的LIBRARY_DIRS，具體實作為：

LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu/hdf5/serial
