  • ubuntu 18.04, 编译运行ORB_SLAM3, 遇到错误Pangolin X11: Unable to retrieve framebuffer options。

    当前问题

    遇到错误Pangolin X11: Unable to retrieve framebuffer options。操作系统是ubuntu 18.04,物理机,不是虚拟机.

    报错Pangolin X11: Unable to retrieve framebuffer options ,修改components/pango_windowing/src/display_x11.cpp,把其中的“GLX_DOUBLEBUFFER , glx_doublebuffer ? True : False,”,改为“GLX_DOUBLEBUFFER , glx_doublebuffer ? False : False,”。重新编译,安装,还是不行。
    对应上面的文章,即使使用2016年发布的Pangolin v0.5, display_x11.cpp的目录不一样,行号也不一样。

    测试Pangolin v0.6,也遇到一样的错误。

    编译ORB_SLAM3

    参考文档

    ORB_SLAM3 安装、编译及测试

    https://blog.csdn.net/weixin_43192983/article/details/119149611
    

    安装依赖包

    sudo apt-get install -y doxygen libgl1-mesa-dev libglew-dev cmake libboost-all-dev
    

    编译ORB_SLAM3遇到的错误

    下面的错误是由于没有安装libboost-all-dev造成的。

    报错Pangolin X11: Unable to retrieve framebuffer options ,修改components/pango_windowing/src/display_x11.cpp,把其中的“GLX_DOUBLEBUFFER , glx_doublebuffer ? True : False,”,改为“GLX_DOUBLEBUFFER , glx_doublebuffer ? False : False,”。重新编译,安装,还是不行。
    对应上面的文章,即使使用2016年发布的Pangolin v0.5, display_x11.cpp的目录不一样,行号也不一样。
