Pangolin 安装测试 Installation & Examination (Ubuntu 20.04)
Pangolin 安装测试 Installation & Examination (Ubuntu 20.04)
下载 dependencies
安装 Pangolin 需要一些准备工作，首先要做的是下载它的一些 dependency：
sudo apt-get install libglew-dev
sudo apt-get install libboost-dev libboost-thread-dev libboost-filesystem-dev
sudo apt-get install ffmpeg libavcodec-dev libavutil-dev libavformat-dev libswscale-dev
# The most important part, or error[1], error[2]
sudo apt-get install libpng-dev
安装&编译
注意上面的都务必先安装成功，最后那个 libpng-dev 很重要，不然直接编译报错 *2。然后就可以从 git 上面把 Pangolin 项目 clone 进来了（当然，此时已经切换到了你习惯存放文件的目录，我这边是 /mnt/...）：
git clone https://github.com/stevenlovegrove/Pangolin.git
输出以下 messages：
Cloning into 'Pangolin'...
remote: Enumerating objects: 5, done.
remote: Counting objects: 100% (5/5), done.
remote: Compressing objects: 100% (5/5), done.
remote: Total 15811 (delta 0), reused 3 (delta 0), pack-reused 15806
Receiving objects: 100% (15811/15811), 4.37 MiB | 16.00 KiB/s, done.
Resolving deltas: 100% (10685/10685), done.
接着切入 Pangolin 目录，开始编译：
cd Pangolin
mkdir build
cd build
记得在编译指令加上 -DCPP11_NO_BOOST=1：
cmake -DCPP11_NO_BOOST=1 ..
输出如下，代表基本成功了：
-- The C compiler identification is GNU 9.3.0
-- The CXX compiler identification is GNU 9.3.0

CMake Warning:
Manually-specified variables were not used by the project:
CPP11_NO_BOOST
-- Build files have been written to: /mnt/c/Users/a1020/Desktop/Reinforcement_ELyou/Demolist/slamdemo/slambook/3rdparty/Pangolin/build
然后就可以进行编译了，为了便于调试，我之前用了 make -j，为的是能够看到更多的信息：
make -j
输出下面这些，没有什么报错，但是 warning 还真不少，虽然也无所谓：

看到上面这些 messages 也可以知道，Pangolin 是一个基于 OpenGL 的项目，能实现数据的可视化。
WSL 专属的 VcXsrv 配置及使用
以上就是安装 Pangolin 的所有步骤了，接下来让我们体验一下它的功能：
cd examples
cd HelloPangolin
mkdir build
cd build
cmake ..
make
./HelloPangolin
按理说，WSL 此时应该画出一个六面体：
没有弹出想要的图像是因为没有安装合适的xming，这里推荐一下 VcXsrv，在Win10里面尝试过了，没有发生什么卡顿以及报错情况，这个软件直接在网站上面下载后，在Win10中随便安装即可，安装路径也可以随便改。在bash中改动一下 DISPLAY 端口即可，进入 .bashrc 或是 .zshrc 文件中进行修改：
nano ~/.zshrc # if you are using bash itself, you may use nano ~/.bashrc
进入后，在文件中加入如下命令（代表采用的是 0 号端口，所以一会打开 VcXsrv 时也把端口命名为 0）：
export DISPLAY=localhost:0
然后刷新一下：
source ~/.zshrc # same as above, use source ~/.bashrc
打开 VcXsrv，选择 Multiple windows，Display number 为 0，Start no client，Clipboard-Primary Selection 选中，禁用 Native opengl，选中 Disable access control，点击完成。这样就可以在运行之前的 examples 了，这里展示一些其它的：
cd ../..
cd SimpleMultiDisplay/build
./SimpleMultiDisplay
输出的是一组拼接图像（和上面的一样为交互式图形）：
