架构Linux | caffe-lstm 构建的未定义引用

Question

我安装了 caffe 没有任何问题，但是当我尝试构建 caffe-lstm 时，我遇到了下一个问题：

在 archlinux 上工作，所有软件包都已安装。我将 blas 设置为 openblas，如

cmake -DBLAS=open ../caffe-lstm/

并在 make.config 文件中修复

BLAS := open

基于 gcc4.9.3 和 g++5.4.0

Answer 1

问题出在 protobuf 和 cuda 中。之后我安装了 protobuf2.5 和 cuda8，没有任何问题。

小贴士： Protobuf 应该从 git 或 sourceforge 下载并编译它。 cuda也一样。 Caffe 不喜欢从存储库下载的库。

Answer 2

我在尝试编译时遇到了同样的问题caffe-fast-rcnn，但是我注意到使用相同的配置（protobuf 和 cuda 版本）编译官方 caffe 版本没有问题。所以比较两个版本我通过在 CAFFE_ROOT/cmake/Dependencies.cmake 添加一行来纠正这个问题：

# ---[ HDF5
find_package(HDF5 COMPONENTS HL REQUIRED)
include_directories(SYSTEM ${HDF5_INCLUDE_DIRS} ${HDF5_HL_INCLUDE_DIR})
list(APPEND Caffe_LINKER_LIBS ${HDF5_LIBRARIES})
list(APPEND Caffe_LINKER_LIBS ${HDF5_HL_LIBRARIES}) #added

此问题已在当前的 caffe 版本中得到纠正，但是如果您尝试基于旧版本编译 fork，您仍然可能会发现它..

Ps : 我使用 cmake 构建。
