C++ 在自定义库中使用正则表达式时出错

我遵循这一点，一切都很好。现在我试着把这个函数

rreplace

像这样放在我自己的库中

myLib.h的内容

#include <regex>

using namespace std;

class myLib {

    private:
        // Some private things

    public:
        // Some public things
        int rreplace (char *buf, int size, regex_t *re, char *rp);
};

---

我正试图用谷歌搜索它，但运气不好。如果问题太简单，我们深表歉意。

错误消息指出您需要使用选项

-std=c++0x

进行编译

g++ -std=c++0x -c myLib.cpp

---

请注意，您正在使用的desn编译器版本未附带正常工作的正则表达式实现。您可以使用不需要使用C++11选项编译的方法。

尝试

int myLib:：rreplace（char*buf，int size，regex\u t*re，char*rp）{}

您可能需要指定regex名称空间。我使用boost，并且通常在我的标题中添加类似的内容：

#include

，

使用namespace std，
使用名称空间stdext
，
使用名称空间boost
