Comment (by anonymous):

 OS : MAC OS X 10.9 (Mavericks)
 Compiler : MacPorts gcc47 4.7.3_3
 Boost version : 1.55 ( BOOST_LIB_VERSION "1_55")

 I installed boost using macports:
 sudo port install boost +universal

 $ ar -tv libboost_thread-mt.a

              U _pthread_mutex_lock
              U _pthread_mutex_unlock

 One can notice the line "U
 __ZN5boost7atomics6detail8lockpool12get_lock_forEPVKv"

 indicating get_lock_for is not defined. This is causing the issue.

 How to get rid of this error?

 I am using cmake and the following line is the verbose output of the make.

 /opt/local/bin/g++ -fPIC -m64 -arch x86_64 -Wall -dynamiclib
 -L/opt/local/lib <all my .o files> -L/opt/local/lib/libboost_thread-mt.a
 …..

 This is resulting in the error.

 But the main concern is the undefined symbols after installing boost.

 why libbbost_thread-mt.a has undefined symbol of get_lock_for.

 Is there any other way/variant of boost which I need to install through
 macports to get rid of this error?
