【声呐仿真】学习记录1.5-使用docker配置dave（先看这个！）、解决一些问题

docker配置dave

1

之前文章中手动配置的环境，在运行dave_demo的时候有报错，很长时间没能解决

所以又试了试官方提供的docker版本，可以正常运行demo

所以建议直接用docker配，除了最开始拉取docker镜像部分有差别，其它基本一样

步骤参考Docker环境|DAVE项目 — Docker Environment | Project DAVE

2

在执行./run.bash -c dockwater:noetic时，如果报错：在运行docker run …时，docker 未找到

关闭ssh，重新连接

然后使用以下命令创建容器（不要复制我的，可能会有信息不一样，复制你报错里的命令。然后可以参照我的，添加一下你需要的，命令介绍在之前的文章里有，dave官方的我也看不懂）：

注意：可能需要删除官方命令中的–rm，我有这个参数的话就会失败（报错docker未找到）

docker run -it -p 50004:22 -v /home/ouc/ros_dave:/home/ouc --name dockwater_noetic_runtime --gpus all -v /dev:/dev -e DISPLAY -e TERM -e XAUTHORITY=/tmp/.dockerpznw0d90.xauth -v /tmp/.dockerpznw0d90.xauth:/tmp/.dockerpznw0d90.xauth -v /tmp/.X11-unix:/tmp/.X11-unix -v /etc/localtime:/etc/localtime:ro -e NVIDIA_DRIVER_CAPABILITIES=compute,utility -e NVIDIA_VISIBLE_DEVICES=all 869c5ad477cb /bin/bash

创建完容器后，就按照我之前的文章，配置可视化、配置cuda、下载代码编译运行，选配ssh远程

运行demo结果如下：

roslaunch dave_demo_launch dave_demo.launch

以下为未完全解决问题的随手记录，待日后解决再补充

1.pcap、png解决，libusb未解决（不要修改libusb相关的）

WARNING ** io features related to openni2 pcap png will be disabled_io features related to openni will be disabled-

经查，png和usb系统都有：

locate libpng | grep cmake
locate libusb

只需安装pcap、配置：

sudo apt-get install libpcap-dev
1

sudo gedit `locate PCLConfig.cmake`
1

搜索openni()，在下面添加：

  elseif("${_lib}" STREQUAL "png")
    find_package(PNG)
  elseif("${_lib}" STREQUAL "pcap")
    find_package(PCAP)  
  elseif("${_lib}" STREQUAL "libusb-1.0")
    find_package(LIBUSB_1)

2.ISO C++

不知道做了什么，突然成功了：

3.换源

ROS换源（除了清华之外的ROS源）-

解决后好了

4.自动安装相关依赖

rosdep install --from-paths src --ignore-src -r -y
