If I recall your library requires a lib to be linked in. That's a deal 
breaker for me. This library seems to move away from that. What I really 
need is captured in my review of John Torjo's second library
<http://lists.boost.org/Archives/boost/2008/02/133462.php>

I'd be interested if either library can support this minimal use case.

If SafeFormat has a maintenance deficit as part of Loki, it would have
the same deficit as part of Boost.  

Also, you might want to take a look at
http://www.boost.org/development/submissions.html to see whether you can
suggest something that fits with the Boost process.  Things don't just
get added; they have to pass through a review process first.

I am inclined the same way, but if they're going to do that, we should
not use a formal review to sort out any large-scale decisions that they
can make between them.

Again, aren't you able to influence that a bit as review wiz?

I know this has been touched before (at least during the library in a week
sessions at BoostCon 2007/2008). Furthermore, the topic of adding some
output formatting facilities to Boost pops up occasionally. 

So, please let me use this thread for a selfless plug :-P. Boost already has
a versatile and powerful output formatting library: Spirit V2! 

You might think, well Spirit used to be a parser library, not something

But I believe there is a wider audience here, thus possibly more
recruits.  And there is at least one other Loki supporter who supports
a move to Boost if possible.

I looked at it before--this is the soliciting interest stage.

Quote.

Determine interest

Potential library submitters should use the Boost developers mailing
list as a forum to gauge interest [in] a possible submission.

End quote.

AT Commands Sample Needed

I need a basic example for sending AT commands to mobile. This will require serial communication on COM
port. If any one can send me any example of it.. I want to do this using BOOST. By searching on GOOGLE I got this
but this is not compiling.

 #include <iostream>
#include <boost/asio.hpp>
#include <boost/asio/serial_port.hpp>
#include <boost/thread.hpp>
#include <boost/system/error_code.hpp>
#include <boost/system/system_error.hpp>
#include <boost/bind.hpp>

void handler(const boost::system::error_code& error)
{

      std::cout << "read" << std::endl;

}

int main(int argc, char* argv[])
{

      using namespace std;
      using namespace boost;
      char read_msg_[512];

      boost::asio::io_service io;

      asio::serial_port theport(io,"COM7");

Don't confuse active development with active maintenance. The Loki developers quickly respond to
questions, which indicates active maintenance.

Adding SafeFormat to boost would probably induce some form of active development (like improving
documentation and regression tests to conform to boost standards), but probably just for a limited time.
Many people today seem to think that things have to constantly change to be "alive". I personally see no
problems if Loki just does a release every three years. Boost currently does four releases per year, if I'm
not mistaken, but so what? What would be the advantages to the users of Loki if it would have four releases
per year?

But I somehow got the impression that this created more problems for boost-users than it solved. People are
often advised to use the distribution from boost.org instead of the one that comes with their GNU/Linux
distribution, because these packages seem to have subtle issues.

But adding SafeFormat to boost would not help me with this, if my code relies much more on Loki.Singleton
than on Loki.SafeFormat. So again, cherry picking libraries from Loki doesn't look like a good solution

The library is very much alive, although for various reasons I didn't

That is true, the library has to be compiled. If it is to support 
multi-module configuration with centralized logging control, I don't see 
how it could be done the other way.

 From what I read there, I'm pretty close to that, aside this part: 
"users of the library must be able to use the libraries without logging 
enabled and pay no cost". The cost will always be there since there will 
be a run time check whether to write logs or not. My lib does filtering 
for that matter.

I couldn't say why it doesn't compile because I've never used Boost.Asio.

For future reference, you should include more details as to why your code
does not compile: operating system, compiler + version, and specific error
messages. Also, questions of this nature are best directed to
boost-users <at> lists.boost.org, not the Boost development list.
