使找不到regex.hpp（boost）

Question

我想編譯一個只有一個文件的小型c + +項目。 BoostRegex.cpp的5個第一行是：

#include <iostream> 
#include <string> 
#include <regex.hpp> 

int main() { .... 

我運行下面的./configure線（這是一個交叉編譯）：

cmake -DCMAKE_TOOLCHAIN_FILE=/home/vitor/bin/raspi/cmaketoolchain/toolchain.cmake ../src/ 

這條線的工作原理與以下輸出：

[vitor@archlinux bin]$ cmake -DCMAKE_TOOLCHAIN_FILE=/home/vitor/bin/rasp/cmaketoolchain/toolchain.cmake ../src/

但是當我運行make命令：

[vitor@archlinux bin]$ make

我必須再次指出boost lib的頭文件嗎？我該怎麼做？

Answer 1

這看起來就像在你的CMakeLists.txt

你是否包括正確迪爾斯爲每FindBoost模塊的錯誤？

include_directories(${Boost_INCLUDE_DIRS})
