高翔:《自动驾驶与机器人中的SLAM技术》-Slam_in_autonomous_driving 编译过程中遇到的问题

本文主要是介绍高翔:《自动驾驶与机器人中的SLAM技术》-Slam_in_autonomous_driving 编译过程中遇到的问题，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

使用的环境是ubuntu20.04

问题1.安装g2o没有问题，不过在编译整个项目工程时候报错：

”openmp_mutex.h: 30:10: fatal error: g2o/config.h: No such file or directory“:

解决办法：

只需要将/thirdparty/g2o/build/g2o下的config.h放到/thirdparty/g2o下：

问题2. No rule to make target ’gmock’，needed by '../bin/test_preintegration' . stop

src/ch4/CMakeFiles/test_preintegration.dir/all] Error 2：

解决办法：将/ch4/CmakeList.txt文件内容修改如下：

# 查找 Google Test，它应该也包含了 Google Mock
find_package(GTest REQUIRED)
include_directories(${GTEST_INCLUDE_DIRS})

# 添加您的库
add_library(${PROJECT_NAME}.ch4
gins_pre_integ.cc
imu_preintegration.cc
g2o_types.cc
)

# 添加您的测试可执行文件
add_executable(test_preintegration test_preintegration.cc)

# 链接 Google Test (它应该包含了 gmock) 以及其他依赖项
target_link_libraries(test_preintegration
${GTEST_BOTH_LIBRARIES}
pthread glog gflags ${PROJECT_NAME}.ch4 ${PROJECT_NAME}.ch3 ${PROJECT_NAME}.common
)

# 添加测试
add_test(NAME test_preintegration COMMAND test_preintegration)

# 添加其他可执行文件
add_executable(run_gins_pre_integ run_gins_pre_integ.cc)
target_link_libraries(run_gins_pre_integ
${PROJECT_NAME}.ch3
${PROJECT_NAME}.ch4
${G2O_LIBS}

问题3.No rule to make target ’gmock’，needed by '../bin/test_nn' . stop

CMakeFiles/Makefile2:4227：src/ch5/CMakeFiles/test_nn.dir/all]

修改/ch5/CMakeList.txt 内容为:

find_package(GTest REQUIRED)

add_executable(point_cloud_load_and_vis point_cloud_load_and_vis.cc)
target_link_libraries(point_cloud_load_and_vis

target_link_libraries(pcd_to_bird_eye

gflags
)

add_executable(scan_to_range_image scan_to_range_image.cc)

add_executable(linear_fitting linear_fitting.cc)
