未定义引用符号'_ULx86_64_step'libunwind.so.8：添加符号时出错：命令行中缺少DSO

Question

I'm trying to compile Caffe.

make all -j4

worked fine. But making the tests is giving the following error.

Debian GNU/Linux 8 (jessie) 64-bit

g++ --version
g++ (Debian 4.9.2-10) 4.9.2

Gives this error on

make test -j4

caffe$ make test -j4

使用cmake方法使Caffe现在似乎已经解决了这个问题。
