boost安裝

1.boost安裝包下載
https://sourceforge.net/projects/boost/files/boost/1.62.0/

2.解壓并進(jìn)入boost_1_62_0文件夾

3.執(zhí)行boostrap.sh

./boostrap.sh

4.上一步執(zhí)行成功后會(huì)生成b2腳本，執(zhí)行它

./b2

執(zhí)行完畢后，頭文件在boost_1_62_0/boost文件夾下
庫文件在boost_1_62_0/stage/lib文件夾下
或者執(zhí)行

./b2 install 

執(zhí)行完畢后頭文件在/usr/local/include下
庫文件在/usr/local/lib下

到這里安裝結(jié)束

測試

直接包含一個(gè)頭文件編譯看是否通過即可

#include <boost/asio.hpp>
int main()
{
}

g++使用第三方庫編譯是如下命令

g++ a.cpp  -I 頭文件路徑 -L 庫文件路徑 -l 動(dòng)態(tài)鏈接庫

對(duì)應(yīng)到我們這里應(yīng)該是

 g++ a.cpp  -I /usr/local/include -L /usr/local/lib -l boost_system -l boost_thread

必須要加，-l boost_system -l boost_thread，否則會(huì)報(bào)錯(cuò)

XCode上使用

1.點(diǎn)擊【項(xiàng)目工程文件】-》【Targets】-》【BuildSetting】-》【Search Paths】-》【Header Search Paths】輸入頭文件路徑
2.點(diǎn)擊【項(xiàng)目工程文件】-》【Targets】-》【BuildSetting】-》【Search Paths】-》【Library Search Paths】輸入庫文件路徑
3.點(diǎn)擊【項(xiàng)目工程文件】-》【Targets】-》【BuildSetting】-》【Linking】-》【Other Linker Flags】輸入鏈接選項(xiàng)，輸入-l boost_system -l boost_thread

大功告成！
