1. 下载Gurobi

注册账号，注意选择类型为学术，然后打开下载中心，选择Gurobi Optimizer点击，同意协议；然后选择最新版本9.0.2的linux压缩包进行下载并解压

2. 配置Gurobi

在Gurobi网站申请学术授权，然后即可看到自己的授权码
假设解压的目录为/home/zfb/gurobi902/linux64/，运行命令：
/home/zfb/gurobi902/linux64/bin/grbgetkey 116e332d-a688-77de-a234-1234aa30bdbe
如果授权成功会在/home/zfb/gurobi902/目录下生成gurobi.lic文件，此时可以通过在终端输入gurobi.sh进入交互环境测试功能是否正常
为了方便使用，修改~/.bashrc文件，添加以下内容：

export GUROBI_HOME=/home/zfb/gurobi902/linux64
export PATH=${PATH}:${GUROBI_HOME}/bin
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${GUROBI_HOME}/lib
export GRB_LICENSE_FILE=/home/zfb/gurobi.lic

然后source ~/.bashrc使文件生效，最好登出再登录一次

3. 安装cgal与cmake

必须保证cmake使用的boost库的版本为1.65（如果为1.70会报错），所以如果原本已有boost1.70则需要手动卸载：

sudo apt-get --purge remove libboost-dev-all
sudo rm -rf /usr/local/lib/boost*
sudo rm -rf /usr/local/include/boost*
# 如果此前未使用过cmake，仅仅安装而已，否则不要执行这一步
sudo apt-get --purge remove cmake
# 删除cmake目录下的boost
sudo rm -rf /usr/local/lib/cmake/boost*
sudo rm -rf /usr/local/lib/cmake/Boost*

开始进行安装：

sudo apt-get install libcgal-dev
sudo apt-get install cmake

4. 安装Qt5

使用以下代码安装Qt5：

sudo apt-get install build-essential manpages-dev
sudo apt install make libqt5widgets5 libqt5gui5 libqt5dbus5 libqt5network5 libqt5core5a
sudo apt-get install qtcreator
sudo apt-get install qt5-default

然后即可运行qtcreator或者点击图标打开项目或创建新项目

5. 下载Polyfit源代码

直接下载最新一次的commit代码，然后解压。假设解压到文件夹/home/zfb/Polyfit/，修改/home/zfb/Polyfit/cmake/FindGUROBI.cmake文件的如下部分：

    # Hardcoded search paths
    set(SEARCH_PATHS_FOR_HEADERS
            "$ENV{GUROBI_HOME}/include"
            "/Library/gurobi901/mac64/include"
            "/home/zfb/gurobi902/linux64/include"
            "C:\\dev\\gurobi901\\win64\\include"
            )

    set(SEARCH_PATHS_FOR_LIBRARIES
            "$ENV{GUROBI_HOME}/lib"
            "/Library/gurobi901/mac64/lib"
            "/home/zfb/gurobi902/linux64/lib"
            "C:\\dev\\gurobi901\\win64\\lib"
            )

然后打开qtcreator软件，选择打开项目，点击Polyfit文件夹下的CMakeLists.txt文件，选择打开，然后点击配置项目，此时即可打开项目并自动执行cmake，然后可以执行编译得到可执行文件，既可以选择生成debug版本，也可以选择release版本
如果遇到以下报错：

[100%] Linking CXX executable ../bin/PolyFit
../math/libmath.so: undefined reference to `GRBaddgenconstrAbs'
../math/libmath.so: undefined reference to `GRBaddgenconstrAnd'

16:55:37: The process "/usr/bin/cmake" exited with code 2.
Error while building/deploying project PolyFit (kit: Desktop)
When executing step "CMake Build"

需要重新生成libgroubi_c++.a文件：

# 进入build文件夹并make生成库
cd gurobi902/linux64/src/build && make
# 移动备份原文件，防止直接覆盖
mv gurobi902/linux64/lib/libgroubi_c++.a ./
# 将生成的文件移动到lib目录
mv ./libgroubi_c++.a ../../lib/

然后再进行编译项目即可
