Subject: [Boost-users] Can't get boost log example to link

hey all

I'm having trouble getting this simple boost log example to link:

#include <boost/log/trivial.hpp>

int main(int, char*[])
{
    BOOST_LOG_TRIVIAL(trace) << " a trace message ";
}

I can compile it ok, but linking causes the below issues:

g++ -o build/main.o -c -std=c++11 -Wall -g -O0 src/main.cpp
g++ -o build/test build/main.o -lboost_log -lboost_log_setup

I using the latest boost-trunk code from svn on Debian 7 Stable 64bit.

Anyone have any ideas?

Cheers

Hi Jarrett,

If I'm not mistaken, you need to have -DBOOST_LOG_DYN_LINK on the compile 
and link command lines.

Leo
