When you extract the library from its zip file, you must preserve its internal directory structure (for example by using the -d option when extracting). If you didn't do that when extracting, then you'd better stop reading this, delete the files you just extracted, and try again!
This library should not need configuring before use; most popular compilers/standard libraries/platforms are already supported "as is". If you do experience configuration problems, or just want to test the configuration with your compiler, then the process is the same as for all of boost; see the configuration library documentation.
The library will encase all code inside namespace boost.
This is a header only library and all support for C++03 compilers has now been removed.
The only people that still need to build the external libboost_regex library are those that are using the deprecated POSIX C API's
Further, this library may now be used in "standalone" mode without the rest of the Boost C++ libraries, in order to do this you must either:
__has_include,
in this case if <boost/config.hpp> is not present then the library will
automoatically enter standalone mode. Or:
If you are using this library with ICU, note that since it is now header only,
it will be up to you to link to the ICU libraries if you use <boost/regex/icu.hpp> unless you are using the supplied CMake
script.
The library comes with a very basic CMakeLists.txt that allows this library to be used from other CMake scripts.
CMakeLists.txt defines two targets:
Boost::regex This is the target to use for normal
header only builds.
Boost::regex_icu This is the target to use if
you are using <boost/regex/icu.hpp> in your code, and wish to have the
ICU dependencies taken care of for you.
There is also one configuration option:
