1.解决方案
将CMakeLists中set(CMAKE_CXX_FLAGS "-std=c++11")注释掉即可
#set(CMAKE_CXX_FLAGS "-std=c++11")
不过编译后运行./visualizeGeometry会有如下报错：

这个估计是WSL系统没有没有配置界面显示所致，待配置了界面显示估计问题就解决了。

1.编译问题
slambook-master/ch4/useSophus/useSophus.cpp:5:10: fatal error: Eigen/Core: No such file or directory

1.解决方案
在CMakeLists中添加Eigen库
# 添加Eigen头文件

#include_directories( "/usr/local/include/eigen3" ) #源码编译安装的eigen库路径

2.解决方案
因新版本Sophus库中头文件名有改变，将代码useSophus.cpp:8中
#include <sophus/so3.h>
#include <sophus/se3.h>
改为
#include <sophus/so3.hpp>
#include <sophus/se3.hpp>

3.解决方案
Sophus库新版本是模板类，定义时需要指定类型，将代码useSophus.cpp中：
Sophus::SO3 SO3_R(R); // Sophus::SO(3)可以直接从旋转矩阵构造
Sophus::SO3d SO3_v( 0, 0, M_PI/2 ); // 亦可从旋转向量构造
Eigen::Quaterniond q(R); // 或者四元数

4.解决方案
因新版本Sophus库打印需要log()函数：，将代码useSophus.cpp中：

改为：
cout<<"SO(3) from matrix: "<<SO3_R.log()<<endl;

没有链接fmt库，链接上fmt 库就没问题了，将CMakeLists.txt中：

请在有pose.txt的目录下运行此程序
5.解决方案
解决办法1：
将make生成的build/joinMap文件复制到pose.txt文件下，在运行./joinMap。
解决办法2：
在joinMap.cpp中：
将ifstream fin("./pose.txt");改为ifstream fin("…/pose.txt");
将boost::format fmt( “./%s/%d.%s” ); 改为boost::format fmt( “…/%s/%d.%s” );
之后保存，重新编译运行即可。

280 | Block* solver_ptr = new Block( linearSolver ); // 矩阵块求解器
8.解决方案
新版本g2o中API接口变了，有两种修改模式，基本意义相同但第一种更简洁：
（1）slambook-master/ch7/pose_estimation_3d2d.cpp解决方案采用第一种方法：参考增加智能指针 std::unique_ptr，第一种方法是根据新版本中的示例来进行语句修改。如下所示：
// 初始化g2o
typedef g2o::BlockSolver< g2o::BlockSolverTraits<6,3> > Block; // pose 维度为 6, landmark 维度为 3
//Block::LinearSolverType* linearSolver = new g2o::LinearSolverCSparse<Block::PoseMatrixType>(); // 线性方程求解器
std::unique_ptr<Block::LinearSolverType> linearSolver ( new g2o::LinearSolverCSparse<Block::PoseMatrixType>());
//Block* solver_ptr = new Block ( linearSolver ); // 矩阵块求解器
//std::unique_ptr<Block> solver_ptr( new Block( linearSolver) );
std::unique_ptr<Block> solver_ptr ( new Block ( std::move(linearSolver))); // 矩阵块求解器
//g2o::OptimizationAlgorithmLevenberg* solver = new g2o::OptimizationAlgorithmLevenberg ( solver_ptr );
g2o::OptimizationAlgorithmLevenberg* solver = new g2o::OptimizationAlgorithmLevenberg ( std::move(solver_ptr));
g2o::SparseOptimizer optimizer;
optimizer.setAlgorithm ( solver );
（2）slambook-master/ch7/pose_estimation_3d3d.cpp解决方案采用第二种方法：根据报错来修改Block的初始化方法，在每个语句对应加入unique_ptr。如下所示：
// 初始化g2o
typedef g2o::BlockSolver< g2o::BlockSolverTraits<6,3> > Block; // pose维度为 6, landmark 维度为 3
Block::LinearSolverType* linearSolver = new g2o::LinearSolverEigen<Block::PoseMatrixType>(); // 线性方程求解器
//Block* solver_ptr = new Block( linearSolver ); // 矩阵块求解器
//std::unique_ptr<Block> solver_ptr ( new Block ( std::move(linearSolver))); // 矩阵块求解器
Block* solver_ptr = new Block( std::unique_ptr<Block::LinearSolverType>(linearSolver) ); // 矩阵块求解器
//g2o::OptimizationAlgorithmGaussNewton* solver = new g2o::OptimizationAlgorithmGaussNewton( solver_ptr );
//g2o::OptimizationAlgorithmGaussNewton* solver = new g2o::OptimizationAlgorithmGaussNewton ( std::move(solver_ptr));
g2o::OptimizationAlgorithmGaussNewton* solver = new g2o::OptimizationAlgorithmGaussNewton( unique_ptr<Block>(solver_ptr) );

optimizer.setAlgorithm( solver );

9.解决方案
（1）DSO missing的原因基本上是因为有库没有连接上，导致未识别。最保险的方法是在最前端将所有库设置为G2O_LIBS：
SET(G2O_LIBS g2o_cli g2o_ext_freeglut_minimal g2o_simulator g2o_solver_slam2d_linear g2o_types_icp g2o_types_slam2d g2o_core g2o_interface g2o_solver_csparse g2o_solver_structure_only g2o_types_sba g2o_types_slam3d g2o_csparse_extension g2o_opengl_helper g2o_solver_dense g2o_stuff g2o_types_sclam2d g2o_parser g2o_solver_pcg g2o_types_data g2o_types_sim3 cxsparse )
（2）由于是在pose_estimation_3d2d中出现问题，所以可以在随后对应的链接中加入${G2O_LIBS}
target_link_libraries( pose_estimation_3d2d
${OpenCV_LIBS}
${CSPARSE_LIBRARY}
g2o_core g2o_stuff g2o_types_sba g2o_csparse_extension ${G2O_LIBS}
)

10.解决方案
（1）报错的意思就是以下运行命令格式不对：
./feature_extraction
./triangulation
./pose_estimation_2d2d
./pose_estimation_3d2d
./pose_estimation_3d3d
正确的命令运行格式应该为：
./feature_extraction img1 img2
./triangulation img1 img2
./pose_estimation_2d2d img1 img2
./pose_estimation_3d2d img1 img2 depth1 depth2
./pose_estimation_3d3d img1 img2 depth1 depth2
如果这些二进制文件feature_extraction、triangulation、pose_estimation_2d2d img1 img2、pose_estimation_3d2d、pose_estimation_3d3d是在源代码目录生成的或者是在新建的build目录中编译生成后移动或者拷贝到源码文件目录下的，实际的运行命令为：

./pose_estimation_3d2d 1.png 2.png 1_depth.png 2_depth.png

如果这些二进制文件feature_extraction、triangulation、pose_estimation_2d2d img1 img2、pose_estimation_3d2d、pose_estimation_3d3d是在新建的build目录中编译生成的不移动或拷贝它们，实际的运行命令为：

3.解决方案
新版本g2o中API接口变了，有两种修改模式，基本意义相同但第一种更简洁：
（1）slambook-master/ch8/directMethod/direct_semidense.cpp解决方案采用第一种方法：参考增加智能指针 std::unique_ptr，第一种方法是根据新版本中的示例来进行语句修改。如下所示：
// 初始化g2o
typedef g2o::BlockSolver<g2o::BlockSolverTraits<6,1>> DirectBlock; // 求解的向量是6＊1的
//DirectBlock::LinearSolverType* linearSolver = new g2o::LinearSolverDense< DirectBlock::PoseMatrixType > ();
std::unique_ptr<DirectBlock::LinearSolverType> linearSolver ( new g2o::LinearSolverDense<DirectBlock::PoseMatrixType>());
//DirectBlock* solver_ptr = new DirectBlock ( linearSolver );
std::unique_ptr<DirectBlock> solver_ptr ( new DirectBlock ( std::move(linearSolver))); // 矩阵块求解器
// g2o::OptimizationAlgorithmGaussNewton* solver = new g2o::OptimizationAlgorithmGaussNewton( solver_ptr ); // G-N
//g2o::OptimizationAlgorithmLevenberg* solver = new g2o::OptimizationAlgorithmLevenberg ( solver_ptr ); // L-M
g2o::OptimizationAlgorithmLevenberg* solver = new g2o::OptimizationAlgorithmLevenberg ( std::move(solver_ptr));
g2o::SparseOptimizer optimizer;
optimizer.setAlgorithm ( solver );
optimizer.setVerbose( true );
（2）slambook-master/ch8/directMethod/direct_sparse.cpp解决方案也采用第一种方法：参考增加智能指针 std::unique_ptr，第一种方法是根据新版本中的示例来进行语句修改。如下所示：
// 初始化g2o
typedef g2o::BlockSolver<g2o::BlockSolverTraits<6,1>> DirectBlock; // 求解的向量是6＊1的
//DirectBlock::LinearSolverType* linearSolver = new g2o::LinearSolverDense< DirectBlock::PoseMatrixType > ();
std::unique_ptr<DirectBlock::LinearSolverType> linearSolver ( new g2o::LinearSolverDense<DirectBlock::PoseMatrixType>());
//DirectBlock* solver_ptr = new DirectBlock ( linearSolver );

6.解决方案
// project中0.1、0.2、0.3、0.4项目中均有此问题。
由于Sophus::SE3和Sophus::SO3在Sophus库新版本中都是模板类，需要声明模板类的数据类型，有两种办法：
（1）一种办法是
using Sophus::SE3;
using Sophus::SO3;
SE3<double> xxx;
SO3<double> yyy;
（2）另一种办法是
using Sophus::SE3d;
using Sophus::SO3d;
SE3d xxx;
SO3d yyy;
采用第二种方法后可将const SE3& T_c_w改为：const SE3d & T_c_w，其他类似地把SE3改为SE3d。最难修改的是T_c_r_estimated_初始化部分，采用第二种方法修改源码如下：
//T_c_r_estimated_ = SE3(
// SO3(rvec.at<double>(0,0), rvec.at<double>(1,0), rvec.at<double>(2,0)),
// Vector3d( tvec.at<double>(0,0), tvec.at<double>(1,0), tvec.at<double>(2,0))
// 此处旋转向量经罗德里格斯转换
Mat R;
cv::Rodrigues(rvec, R);
Eigen::Matrix3d RE;
RE << R.at<double>(0,0), R.at<double>(0,1), R.at<double>(0,2),
R.at<double>(1,0), R.at<double>(1,1), R.at<double>(1,2),
R.at<double>(2,0), R.at<double>(2,1), R.at<double>(2,2);
// SO3构造函数参数为旋转矩阵
T_c_r_estimated_ = SE3d(
SO3d(RE),
Vector3d(tvec.at<double>(0,0), tvec.at<double>(1,0), tvec.at<double>(2,0)));

12.解决方案
//TODO有待解决， 0.4项目中均有此编译问题
- slambook-master/ch10
1.编译问题
/mnt/d/slam14/slambook-master/ch10/ceres_custombundle/common/BALProblem.cpp:8:10: fatal error: Eigen/Core: No such file or directory
8 | #include <Eigen/Core>
1.解决方案
在CMakeLists中添加"/usr/include/eigen3"，如下所示：
include_directories(${CERES_INCLUDE_DIRS}
${PROJECT_SOURCE_DIR}/common
${PROJECT_SOURCE_DIR}/common/tools
${PROJECT_SOURCE_DIR}/common/flags
"/usr/include/eigen3" )
2.编译问题

64 | struct SumImpl<std::integer_sequence<T, N, Ns...>> {
2.解决方案
在CMakeLists中添加set( CMAKE_CXX_STANDARD 14)
3.编译问题
/mnt/d/slam14/slambook-master/ch10/ceres_custombundle/ceresBundle.cpp:17:14: error: ‘struct ceres::Solver::Options’ has no member named ‘num_linear_solver_threads’; did you mean ‘linear_solver_type’?
17 | options->num_linear_solver_threads = params.num_threads;
| ^~~~~~~~~~~~~~~~~~~~~~~~~
| linear_solver_type
3.解决方案
规避的话注释掉options->num_linear_solver_threads = params.num_threads;
//options->num_linear_solver_threads = params.num_threads;
更好的方法是用“options->num_threads = params.num_threads;”替换原来的“options->num_linear_solver_threads = params.num_threads;”
这是因为“Solver::Options::num_linear_solver_threads is deprecated, Solver::Options::num_threads controls all parallelism in Ceres Solver now.“
4.编译问题
slambook-master/ch10/ceres_custombundle/build# ./ceres_customBundle
Usage: bundle_adjuster -input <path for dataset>
4.解决方案
运行命令应该按照bundle_adjuster -input <path for dataset>，故修改运行命令如下：
./ceres_customBundle -input ../data/problem-16-22106-pre.txt

应该是由于wsl没有安装UI界面，导致编译的程序调用界面显示时不能显示所致。
其他说明
