I use boost date_time library in my program. And I fall in trouble.
I can not build my program, there occurs some link errors.
I'v ran bjam in boost_1_29_0/libs/date_time/build/ , and get a lib file in
boost_1_29_0/libs/date_time/build/bin/libboost_date_time.a/gcc/debug/ . I copy
it to my lib directory, and then build my program, the link errors seem less,
as the list.
All these occurs on Redhat Linux 7.1, with GCC 2.96. And the makefile is
generated by Kdevelop 2.0.

But my program still can not build. Help me! Thanks.
