[Boost-users] Locale on Mac OS X

[Alberto Simões]

Hello, friends

I am kind of desesperate.

I am trying to use a Natural Language Processing application written
in C++ that uses libboost on my Mac OS X.

The problem is that locales seem to be broken for C++ in darwin. I
know that is is (as far as I can tell) libboost fault. If you run the
c++ program in attach under Leopard, you get the behavior I paste
below.

My question is: anybody found a way to make locale working on darwin?
Couldn't libboost try to implement an indirection level for mac os X
using the C locale API? (not sure if you are interested, just an
idea).

Please let me know if there is a solution to this problem.

Kindest regards,
Alberto

I'm not sure if this will meet your needs but the upcoming release of boost will include a locale library. You can see the documentation at:

http://svn.boost.org/svn/boost/branches/release/libs/locale/doc/html/index.html

If it doesn't depend on system locale (didn't have the time to look to
it yet) it might be a solution (if I can convince the package
developer to port his C++ locale code to boost locale).

Thank you.
This might be really helpful.
