# Ubuntu 20.04 LTS 編譯 OpenPose

+ ## 環境
+ `Ubuntu 20.04 LTS`

+ ## 相依套件安裝

sudo apt install protobuf-compiler
sudo apt install libboost-all-dev
sudo apt install libgflags-dev
sudo apt install libblas-dev
sudo apt install libgoogle-glog-dev
sudo apt install libhdf5-dev
sudo apt install liblmdb-dev
sudo apt install libleveldb-dev
sudo apt install libsnappy-dev

+ ## Caffe
+ [ambersun1234/caffe](https://github.com/ambersun1234/caffe) 有對 **opencv 4.5.0** 的支援
+ 系統內需要有 `OpenCV` $\geq$ 2.4
+ 解除 error 訊息

    sudo vim /usr/include/crt/host_config.h
    // line 138
    // #error -- unsupported GNU version! gcc versions later than 8 are not supported!

+ `CMakeLists.txt`

+ 安裝

        mkdir -p ~/library
        cd ~library && git clone https://github.com/CMU-Perceptual-Computing-Lab/caffe
        
        mkdir -p caffe/build
        cd build && cmake ..
        make all -j`nproc`
        make runtest -j`nproc`
        sudo make install -j`nproc`

+ 額外設定

        cd ~/library/caffe
        protoc src/caffe/proto/caffe.proto --cpp_out=.
        mkdir include/caffe/proto
        mv src/caffe/proto/caffe.pb.h include/caffe/proto

+ ## OpenPose

    git clone https://github.com/CMU-Perceptual-Computing-Lab/openpose
    cd openpose
    mkdir build && cd build
    cmake -D Caffe_INCLUDE_DIRS:PATH="/home/USER/library/caffe/include" -D BUILD_PYTHON:BOOL="1" -D BUILD_CAFFE:BOOL="0" -D Caffe_LIBS:FILEPATH="/home/USER/library/caffe/build/lib/libcaffe.so" ..
    make -j`nproc`
    sudo make install j`nproc`
