c++ - libcudart.so.5.5，/usr/local/lib/libopencv_core.so 需要

Question

我的电脑是CentOS系统，我尝试安装caffe。安装一些依赖项后。我运行 $make all，然后它返回以下警告:

NVCC src/caffe/solvers/sgd_solver.cu
NVCC src/caffe/solvers/rmsprop_solver.cu
NVCC src/caffe/solvers/adam_solver.cu
AR -o .build_release/lib/libcaffe.a
LD -o .build_release/lib/libcaffe.so
CXX tools/test_net.cpp
CXX/LD -o .build_release/tools/test_net.bin
/usr/bin/ld: warning: libcudart.so.5.5, needed by /usr/local/lib/libopencv_core.so, may conflict with libcudart.so.6.0
CXX tools/upgrade_net_proto_binary.cpp
CXX/LD -o .build_release/tools/upgrade_net_proto_binary.bin
/usr/bin/ld: warning: libcudart.so.5.5, needed by /usr/local/lib/libopencv_core.so, may conflict with libcudart.so.6.0

我检查了cuda的版本:$nvcc -V，它返回:

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2013 NVIDIA Corporation
Built on Wed_Jul_17_18:36:13_PDT_2013
Cuda compilation tools, release 5.5, V5.5.0

我输入/usr/local，显示: wathet blue cuda file ，我进入usr/local/cuda/lib，里面有libcudart.so.6.0!但是 libcudart.so.5.5 文件在 /usr/local/cuda-5.5/lib 中。我不知道如何制作/usr/local/lib/libopencv_core.so 需要的 libcudart.so.5.5。那么如何解决这个问题呢？

Answer 1

您的 opencv 是使用 cuda 支持构建的，并且与 cuda 5.5 相关联。请尝试此命令以确保相关性

ldd/usr/local/lib/libopencv_core.so

...如果 opencv 依赖于 cuda 5.5，请使用 cuda 5.5 构建你的 caffe，或者你需要在你的机器上从源代码构建 opencv，它会自动找到 cuda 6.0
