我试图在Linux机器上安装Boost(CentOs,Linux版本2.6.9-67.ELsmp).我按照Boost 入门网页上的说明进行操作.下载并解压缩文件,然后我添加前缀,因为我不是root用户.

./bootstrap.sh --prefix=/my_path/boost-1.49.0
./b2 install

我转到/my_path/boost-1.49.0并检查那里有/ include/boost /和/ lib /包含文件.

我也将LD_LIBRARY_PATH设置为/my_path/boost-1.49.0/lib/.

要测试我是否成功安装,我编译以下代码:

main.cpp中

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

using namespace boost;
using namespace std;

int main(int argc, char *argv[])
{
    string line = "12345";
    regex pattern("^123");
    if (regex_match(line, pattern)) cout << "match." << endl;
    else cout << "not match." << endl;
    return 1;
}

并按命令编译:

g++ -v -I /my_path/boost-1.49.0/include/boost -L /my_path/boost-1.49.0/lib main.cpp -lboost_regex -o example

并生成以下错误:
