boost log with boost 1.48 on OSX 10.7.2

I pulled the latest BOOST log from https://boost-log.svn.sourceforge.net/svnroot/boost-log/trunk/ and tried building it against my current BOOST install (1.47) on osx lion (10.7.2) and it complained that it needed boost 1.48.

So I pulled down and built BOOST 1.48 which all went fine. I then updated my BOOST install , and ran bootstrap like this:

/bootstrap.sh --with-libraries=log --prefix=/usr/local 
    --includedir=/usr/local/include --libdir=/usr/local/lib

all fine at this point. Now however, when I run:

sudo ./b2

I get the following errors:

I looked at the BOOST log install stuff and there are a few directives but nothing obvious about this. Anyone give me a few clues about this? I'm finding nothing in stack overflow or on the web which does make me think i'm missing something. The posix timers not being supported is a pretty definitive message...

thanks in advance.

This issue has been fixed in r655.

The problem is that Darwin does not feature the POSIX extension which provides clock_gettime(). However, Darwin does have a high-resolution monotic clock available in mach/mach_time.h called mach_absolute_time(). As of r655, Boost Log uses this function on Mac OS.

If you want to install the most recent Boost version without any pain, plus enjoy the benefits of C++11, check out my custom Portfile. For example, it allows you to install Boost as follows:

sudo port install boost +cxx11 +log +debug +no_single

where the +log variant pulls the most recent SVN version.

Briefly looking at the code it appears boost-log wasn't written to support Mac OS X which does not have an an implementation of Posix timers.
