#9657: Boost Log V2 Library Android Linking
------------------------------+------------------------------
 Reporter:  Guven <guveni@…>  |       Type:  Bugs
   Status:  new               |  Milestone:  To Be Determined
Component:  Building Boost    |    Version:  Boost 1.55.0
 Severity:  Problem           |   Keywords:
------------------------------+------------------------------
 I am trying to build Boost 1.55 Log v2 library on Android using NDK 9C. I
 have used the patches and build the boost using build-android.sh including
 thread,iostreams,random and log options. I have used the other features of
 Boost and they have worked. But there seems to be linking problem with the
 Log V2 on NDK 9c 64 bit which I could not solve with the existing
 solutions. I keep getting the same "undefined reference" error. On the web
 people solved this problem including "#define BOOST_ALL_DYN_LINK" but it
 did not work for me.
 The build-android.sh file option
 LIBRARIES=--with-
 libraries=date_time,filesystem,program_options,regex,signals,system,thread,iostreams,random,log
