Package: libboost-regex1.34.0
Version: 1.34.0-1+b1
Severity: normal
Attempting to use boost::smatch::captures( int i ) in a program (as a member
method call, not a class method call) results in my compiler complaining that
above method, which according to boost's documentation exists, doesn't exist. I
attempted to compile the example found at
http://boost.org/libs/regex/doc/captures.html in the "Repeated Captures"
section and attempted to compile it with:
$ g++ -o boostRegex -lboost_regex main.cpp

Hello,
The example you tried [1] exercises an *experimental* feature. At the
end of the page we see:
Unfortunately enabling this feature has an impact on performance
(even if you don't use it), and a much bigger impact if you do use
it, therefore to use this feature you need to:
* Define BOOST_REGEX_MATCH_EXTRA for all translation units including
the library source (the best way to do this is to uncomment this
define in boost/regex/user.hpp and then rebuild everything.
The Debian packages are *NOT* built with BOOST_REGEX_MATCH_EXTRA, and
given the caveat about performance, I do not think we will do so.
Regards,
-Steve
