1. 使用visual studio編譯
win10 vs2015編譯過程
https://www.freesion.com/article/6535119376/
總結(jié)：還是要使用vs2015，在本次項(xiàng)目中使用的是log4cplus的1.2.x版本温治，使用2015編譯 debug-win32模式霹购。
2. 使用gcc 和 make 編譯
# 下載
git clone --recurse-submodules https://github.com/log4cplus/log4cplus.git
# 進(jìn)入目錄
cd log4cplus
mkdir build
cd build
# 編譯 需要指定自己的gcc路徑
../configure CC=/usr/local/bin/gcc-11 CXX=/usr/local/bin/g++-11 --prefix=/tmp/LearnLogJ4 --enable-static
make
make install
# 現(xiàn)在include和lib庫應(yīng)該在/tmp/LearnLogJ4路徑下
# 只需要使用liblog4cplus.a即可
樣例
//使用log4cplus六個(gè)基本步驟
/**
* 實(shí)例化一個(gè)封裝了輸出皆知的appender對象
* 實(shí)例化一個(gè)封裝格式的layout對象
* 將layout對象綁定到appender對象
* ‘實(shí)例化一個(gè)封裝了日志輸出的logger'對象 并調(diào)用靜態(tài)函數(shù)getinstance獲得實(shí)例
* 將appender對象綁定到logger對象
* 設(shè)置logger的優(yōu)先級 省略將輸出所有等級的日志
