ORB-SLAM2安装以及遇到问题

Ubuntu16.04跑ORB_SLAM项目
所用显卡：GeForce RTX 2070
显卡驱动：NVIDIA-SMI 410.78
CUDA Version: 10.0
cudnn :7.5.0
查看CUDA版本：nvcc -V
cudnn版本：cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2
查看显卡信息：nvidia-smi
安装caffe前的工作：Ubuntu16.04 Caffe 安装步骤
或者在参考caffe安装步骤
编译caffe前过程中会报一些错误：
1.Ubuntu16.04 编译 opencv 出现错误：Unsupported gpu architecture ‘compute_20’
可参考：参考

安装opencv2.4.11
可以参考

安装caffe两种方式：
make传统:

make all
make test
make runtest

cmake专业:

mkdir build
cd build
cmake ..
make all
make install
make runtest

编译caffe遇到问题及解决:

1.安装lmdb

sudo apt-get install libffi-dev python-dev build-essential
sudo pip install lmdbpip(升级pip install --upgrade pip)之后
使用sudo pip install lmdb出错
Traceback (most recent call last):File "/usr/bin/pip", line 9, in <module>from pip import main
ImportError: cannot import name main这时打开了pip文件，修改from pip import main  if __name__ == '__main__':  sys.exit(main())
为from pip import __main__  //修改if __name__ == '__main__':  sys.exit(__main__._main())//修改

cmake专业方法:

1.cmake …报错

CMake Error at /usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:148 (message):Could NOT find LMDB (missing: LMDB_INCLUDE_DIR LMDB_LIBRARIES)
Call Stack (most recent call first):/usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE)cmake/Modules/FindLMDB.cmake:19 (find_package_handle_standard_args)cmake/Dependencies.cmake:60 (find_package)CMakeLists.txt:49 (include)

操作：

sudo apt install libgflags-dev libgoogle-glog-dev liblmdb-dev -y

还是报错：

CMake Error at /usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:148 (message):Could NOT find LevelDB (missing: LevelDB_INCLUDE LevelDB_LIBRARY)
Call Stack (most recent call first):/usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE)cmake/Modules/FindLevelDB.cmake:18 (find_package_handle_standard_args)cmake/Dependencies.cmake:71 (find_package)CMakeLists.txt:49 (include)

操作：

sudo apt install libgflags-dev libgoogle-glog-dev libleveldb-dev -y

3.报错：

Could NOT find Snappy

操作：

sudo apt-get install libsnappy-dev

2.make all时报错：

由于我系统装的protoc装的版本是ptotoc2.6.1而项目用的是protoc2.5.0
所有要卸载2.6.1装2.5.0

查看自己的protoc版本：protoc --version
下载好后，安装：

./autogen.sh;
./configure;
make;
make check;
sudo make install;
sudo ldconfig;

4. make runtest报错

还未解决，貌似可以不跑！

传统make方法

编译caffe时，遇见boost函数undefined reference to `boost::xxxxxx修改makefile文件，将需要的boost::xxxxxx库，加到LIBRARIES后面

例如：

.build_release/lib/libcaffe.so: undefined reference to `boost::cpp_regex_traits<char>::toi(char const*&, char const*, int) const'
.build_release/lib/libcaffe.so: undefined reference to `boost::re_detail::get_default_error_string(boost::regex_constants::error_type)'
.build_release/lib/libcaffe.so: undefined reference to `boost::re_detail::cpp_regex_traits_implementation<char>::transform(char const*, char const*) const'
.build_release/lib/libcaffe.so: undefined reference to `boost::re_detail::put_mem_block(void*)'
.build_release/lib/libcaffe.so: undefined reference to `boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > >::do_assign(char const*, char const*, unsigned int)'
.build_release/lib/libcaffe.so: undefined reference to `boost::re_detail::raise_runtime_error(std::runtime_error const&)'上面错误是 undefined reference没有将regex填入LIBRARIES 中修改LIBRARIES ，将boost_regex加入进去# We will also explicitly add stdc++ to the link target.
LIBRARIES +=  boost_regex boost_atomic boost_thread stdc++

1.错误：

ckq@ckq:~/projects/ORB_SLAM2/Thirdparty/caffe$ make runtest -j8

2.错误

解决：类似于超级连接的作用

sudo ln -s /home/ckq/projects/ORB_SLAM2/Examples/ROS/ORB_SLAM2 /opt/ros/kinetic/share/ORB_SLAM2

项目中ros的编译：

自己安装好ros:

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654sudo apt-get updatesudo apt-get install ros-kinetic-desktop-fullsudo rosdep initrosdep updateecho "source /opt/ros/kinetic/setup.bash" >> ~/.bashrcsource ~/.bashrc

卸载：

sudo apt-get  remove ros-kinetic-desktop-fullsudo apt-get purge ros-*
sudo rm -rf /etc/ros
gedit ~/.bashrc
