下載並安裝 MinGW https://sourceforge.net/projects/mingw/
安裝下圖出現的套件
添加環境變數如下
下載 CUnit-2.1-3 https://sourceforge.net/projects/cunit/
複製 CUnit-2.1-3 到 (C:\MinGW\msys\1.0\home) ，並解壓縮
啟動 MSYS，預設路徑 (C:\MinGW\msys\1.0\msys.bat)，並執行以下命令
cd /home/CUnit-2.1-3 | |
./boostrap | |
make | |
make install |
複製 C:\MinGW\msys\1.0\home\User\CUnitHome\lib 底下的 libcunit.a 到 C:\MinGW\lib
複製 C:\MinGW\msys\1.0\home\User\CUnitHome\include 底下的 CUnit 到 C:\MinGW\include
# Linux
更新 apt 資料庫
sudo apt update |
安裝以下套件
sudo apt install gcc g++ lcov | |
sudo apt install libcunit1 libcunit1-dev libcunit1-doc libcunit1-ncurses libcunit1-ncurses-dev |
