Problem for init this project

[infinitysky]

Hi all

I am trying to rebuild this project, and I already completed all the libraries installation process.

However, I meet a problem with stage2 build:

 Build
Clone the repository and catkin_make:

    cd ~/$A_ROS_DIR$/src
    git clone https://github.com/hku-mars/FAST_LIO.git
    cd FAST_LIO
    git submodule update --init
    cd ../..
    catkin_make
    source devel/setup.bash
Remember to source the livox_ros_driver before build (follow 1.3 livox_ros_driver)
If you want to use a custom build of PCL, add the following line to ~/.bashrc export PCL_ROOT={CUSTOM_PCL_PATH}

when I running git submodule update --init commond I found this error messing

is any one has idea to resolve it?

thank you

这个问题我也遇到过，你可以参考一下下图中的解决方案：对FAST_LIO文件夹下面的隐藏文件.gitmodules进行修改，打开文件，把 git 形式的 url 改为 https 形式。

除外，我把我之前测试fastlio的整个过程都记录在了下面这篇文章中，包括后面的 rosbag example，你都可以参考一下。 https://zhuanlan.zhihu.com/p/461246350

非常感谢几位的回复的帮助

我之前是直接删除 include\ikd-Tree 这个文件夹，然后直接在 include 这个文件夹项目做 git clone https://github.com/hku-mars/ikd-Tree完成的

感谢几位的时间和帮助，谢谢
