如你所见,你把正则表达式和要分析的字符串传递给算法regex_match. 如果的确存在与正则表达式的匹配,则该函数调用返回结果true;否则,返回false. 在这个例子中,结果是false, 因为regex_match仅当整个输入数据被正则表达式成功匹配时才返回true。你知道为什么是这样吗?再看一下那个正则表达式。第一个字符是大写的A, 很明...
单独编译了regex,生成了libboost_regex-gcc-1_34.a,现在试验regex能否生效,代码如下: CODE: #include<boost/regex.hpp> int main(int argc,char * argv[]) { boost::regex e("test"); return 0; } #g++ regex.cpp -I /path/to/boostroot -L/path/to/libboost_regex-gcc-1_34.a -o regex 报错:...

We shall now take a look at another of Boost.Regex's algorithms, regex_search. The difference from regex_match is that regex_search does not require that all of the input data matches, but only that part of it does. For this exposition, consider the problem of a programmer who expects ...

在开始编译boost之前,建议先将依赖包都装一遍: yum -y install gcc gcc-c++ python python-devel libicu libicu-devel zlib...zlib-devel bzip2 bzip2-devel 其中,部分依赖包的提示信息如下:提示信息【Unicode/ICU support for Boost.Regex?...-devel 】注意:如果编译失败了,建议用 rm -rf 全删了之后,重新解...
