bcp（Boost）复制最小子集库依赖项

Question

I am currently trying to copy a subset of regex (also known as regular expressions) library and its dependencies so I can bring it to school to work with. I could be using Microsoft's regular expressions from the C++11 standard library, but my school's computers do not support the C++11 library.

Anyways, to make this possible, I have compiled the bcp tool successfully and I have typed bcp boost/regex.hpp <my destination folder> on my command prompt window.

The problem is that I get the following error:

**** exception(205): std::runtime_error: Found a closing ) with no corresponding openening parenthesis.  The error occurred while parsing the regular expression fragment: "?+(([(<].*HERE>>>)?$)?".

Any kind of advice would be appreciated.

Answer 1

Very peculiar. The quoted code has an OPENING ( with no corresponding closing parenthesis. Try escaping the open parenthesis with a slosh \\:

"?+(([\(<].*HERE>>>)?$)?"

This would not alter the regular expression, but may help the parser.
