一、

/usr/include/eigen3/Eigen/src/Core/AssignEvaluator.h:745:3: error: static assertion failed:YOU_MIXED_DIFFERENT_NUMERIC_TYPES__YOU_NEED_TO_USE_THE_CAST_METHOD_OF_MATRIXBASE_TO_CAST_NUMERIC_TYPES_EXPLICITLY
　　EIGEN_CHECK_BINARY_COMPATIBILIY(Func,typename ActualDstTypeCleaned::Scalar,typename Src::Scalar);

问题原因：Eigen3的bug

解决方法：打开Thirdparty/g2o/g2o/solvers/linear_solver_eigen.h，将以下代码

template 
class LinearSolverEigen: public LinearSolver
{
  public:
    typedef Eigen::SparseMatrix SparseMatrix;
    typedef Eigen::Triplet Triplet;
    typedef Eigen::PermutationMatrix PermutationMatrix;

改为

template 
class LinearSolverEigen: public LinearSolver
{
  public:
    typedef Eigen::SparseMatrix SparseMatrix;
    typedef Eigen::Triplet Triplet;
    typedef Eigen::PermutationMatrix PermutationMatrix;
    /**

 

二、

找不到catkin的包，catkin_make和catkin_init_workspace 等命令都使用不了，

sudo aptitude install catkin

 

解决方案，重新安装catkin

三、caffe/blob.hpp:9:34: fatal error: caffe/proto/caffe.pb.h: 没有那个文件或目录

# In the directory you installed Caffe to
protoc src/caffe/proto/caffe.proto --cpp_out=.
mkdir include/caffe/proto
mv src/caffe/proto/caffe.pb.h include/caffe/proto

四、

caffe/util/io.hpp:8:18: fatal error: hdf5.h: No such file or directory

在Makefile.config文件的第85行，添加/usr/include/hdf5/serial/ 到 INCLUDE_DIRS，也就是把下面第一行代码改为第二行代码。

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

 如果都不行，则

#include "hdf5.h" 修改为 #include "hdf5/serial/hdf5.h"
