g++ static link error against Boost.Log

Question

I get link errors when statically linking against Boost.Log. The compiler version is g++ 4.8.1. Boost version is 1.55.0. I can do a dynamical link without problems (with a "-DBOOST_LOG_DYN_LINK" in make file) but when I do the static link, I get link errors. This problem won't happen on other boost libraries. I simplified my code to reproduce this issue easily:

#include <boost/log/trivial.hpp>
int main()
{
    BOOST_LOG_TRIVIAL(trace) << "test trace";
    return 0;
}

The build command that generates link errors:

g++ test.cpp -lboost_thread -lboost_log

However, if I specify the lib file explicitly, there will be no problems:

g++ test.cpp -lboost_thread /usr/local/lib/libboost_log.a

I also tried to add -L options and get the same erros:

g++ test.cpp -L/usr/local/lib -lboost_thread -lboost_log

Here's the error log:

Just a point of clarification: The example you show that works is statically linked (at least against `libboost_log.a`) and the example that fails is (presumably) dynamically linked. — Joe Z, Dec 16 '13 at 06:38
But why does my program that uses Boost.FileSystem and Boost.Program_Options work? I add -lboost_filesystem and -lboost_program_options and no link error occurred. The program also works fine on other machines that don't have these .so file. — avhacker, Dec 16 '13 at 09:32
In this case, -lboost_log_setup is not required. Adding that option also result in the same errors. — avhacker, Dec 16 '13 at 11:01
I think I know where the problem is. I thoguhg -lboost_xxx is static link but actually it's not. — avhacker, Dec 16 '13 at 11:18

I'm pretty sure that by this time you already have your answer, but just in case, you needed to add the BOOST_LOG_DYN_LINK definition.

g++ -DBOOST_LOG_DYN_LINK logging_test.cpp -lboost_log -lpthread

With that command it should be running now.

Have you ever seen this page :

http://www.boost.org/doc/libs/1_55_0/libs/log/doc/html/log/rationale/namespace_mangling.html

I suggest you to go to configuration page of boost log and make your project again with proper options.
