wsl2+ubuntu20安装ros2遇到update问题

catkin_make_isolated --install --use-ninja用这个指令编译的时候，报错对‘google::LogMessage::LogMessage(char const*, int, int, unsigned long, void ........往上翻一点发现一个CMake 的Warnning：runtime library [libglog.so.0] in /usr/lib/x86_64-linux-gnu may be hidden by file in /

按照官方教程安装cartographer的时候：wstool merge -t src https://raw.githubusercontent.com/googlecartographer/cartographer_ros/master/cartographer_ros.rosinstall报错：ERROR in config: Unable to download URL [https://raw.githubusercontent.com/googlecartographer/cartogr

又又又又遇到错误了no matching function for call to ‘getOptimalNewCameraMatrix’这次是因为本机中用的opencv版本和kalibr所需的冲突了。所以需要安装opencv2.4.13（我用的是这个）注意安装的时候设置一下INSTALL_PREFIX，否则会和原来的版本冲突。然后在kalibr中修改一下CMakeLists.txt（主要是include_directories和target_link_libraries）就OK了...

编译时爆出如下错误error: no matching function for call to ‘aslam::backend::ErrorTermFs<DIMENSION>::evaluateJacobians(aslam::backend::JacobianContainer&) const’ aslam::backend::ErrorTerm::evaluateJacobians(J);看源代码发现函数evaluateJacobians是在ErrorTerm中

如题，在用catkin编译时报错：/home/zhiyu/kalibr_workspace/src/kalibr/aslam_cv/aslam_time/include/aslam/implementation/Time.hpp:153:37: error: no matching function for call to ‘boost::date_time::subsecond_duration<boost::posix_time::time_duration, 1000000>::subs

如题，在使用如下指令时catkin build -DCMAKE_BUILD_TYPE=Release -j4报错“无法本地校验颁发者的权限”。这个是在catkin编译的过程中使用wget从网上下载suitesparse时，产生的错误。可以通过修改CMakeLists.txt来解决：vim ~/kalibr_workspace/src/kalibr/suitesparse/CMakeLists.txt将其中的DOWNLOAD_COMMAND rm -f SuiteSparse-${VERSI
