Boost + Mingw-w64 + Boost log won't work

Question

I've got boost compiled, cmake working, and everything is close to working, yet the simplest of examples (trivial logging) fails to compile with a linker error. I really don't know what to do.

Here is my current CMake setup

FIND_PACKAGE(Boost 1.54.0 COMPONENTS log log_setup REQUIRED)
...
TARGET_LINK_LIBRARIES(cogtd ${LIBS} ${SDL2_LIBRARY} ${CMAKE_THREAD_LIBS_INIT} ${Boost_LIBRARIES})

Here is the error log

Boost is compiled to use dynamic libraries.

I'm using Boost-1.54, Mingw-w64 4.8.1 rev 5 (the x64 seh posix version) and Cmake 2.8.11 I've tried static linking to no avail.

Answer 1

add this to compile command and try again

-DBOOST_LOG_USE_NATIVE_SYSLOG

Answer 2

Configuring and building the library indicate that if you want to link to the shared version, it seems you need to define BOOST_LOG_DYN_LINK or BOOST_ALL_DYN_LINK. Add this to compile command: -DBOOST_LOG_DYN_LINK
