Boost logger linking issue

Question

I am writing a program which uses Boost libraries. I had no problems with linking and using program options but I can't seem to make boost log working correctly. Could anyone tell me what am I missing?

jamroot.jam

using clang : : : <compileflags>-Isrc/main/headers <compileflags>-std=c++11 <compileflags>-stdlib=libc++ <linkflags>-std=c++11 <linkflags>-stdlib=libc++ ;
lib boost_program_options boost_log ;
exe foghorn : [ glob src/main/cpp/*.cpp ] boost_program_options boost_log ;

This is the error I am getting:

Answer 1

I had the same issue and in my case the problem was that I had boost compiled with dynamic libs only, and forgot to define BOOST_ALL_DYN_LINK.

http://www.boost.org/doc/libs/1_54_0/libs/log/doc/html/log/rationale/namespace_mangling.html

As a test, try to compile

http://www.boost.org/doc/libs/1_54_0/libs/log/example/doc/tutorial_fmt_stream.cpp

(#include <boost/log/support/date_time.hpp> should be added, the example is broken.)

and also add #define BOOST_LOG_DYN_LINK

I could compile the example with g++ tutorial_fmt_stream.cpp -Wall -L$BOOST/lib/ -I $BOOST/include/ -pthread -lboost_system -lboost_log_setup -lboost_log -lboost_date_time -lboost_thread -lrt -lboost_filesystem

If you are using cmake to manage your boost, just don't forget to have something like:

add_definitions(-DBOOST_LOG_DYN_LINK)

in your CMakeLists.txt

Answer 3

I had the same problem, which was a complicated linkage path. The message shows that is trying to link with the static libraries ( ....v2s ...), but the linker is only giving it dynamic libraries (because it is stupid).

Your build of Boost might be generating both .so and .a files, and gcc gets confused when both are present.

I had a library built with CMake that uses static Boost libraries. If you link this library to a program using a Makefile flow, the program needs to also specify the same static Boost libraries. However, the -l option for the linker is vague and not your friend here. If you built Boost to have both static (.a) and dynamic (.so) outputs, then the linker will chose the dynamic (.so) files first if you just use the -l option.

The workaround is to not use the -L and -l options to find the Boost static libraries (since it will fail), but to specify the full paths to the Boost libraries. For example,

gcc .... -L/opt/boost_1.55/lib -lboost_log

change to

gcc .... /opt/boost_1.55/lib/libboost_log.a

Another option is to specify the word -static to gcc, but this requires all libraries to be static, which probably won't work if you use anything besides boost (say the librt.so library).

Answer 4

If you are using

void boost::log::v2s_mt_posix::init_from_stream<char>(std::basic_istream<char, std::char_traits<char> >&)

function, then you need to link

libboost_log_setup.a
