Hi list.

This does not compile though this is the program shown in the document. The errors are:

/usr/lib/gcc/x86_64-redhat-linux/4.0.2/../../../../lib64/crt1.o (.text+0x20): In function `_start': : undefined reference to `main' /tmp/ccytTZBu.o(.text+0x8f): In function `force_division_by_zero()': backoff_ngram_lm_test.cpp: undefined reference to `boost::test_tools::tt_detail::check_impl(boost::test_tools:: predicate_result const&, boost::basic_wrap_stringstream<char>&, boost::unit_test::basic_cstring<char const>, unsigned long, boost::test_tools::tt_detail::tool_level, boost::test_tools::tt_detail::check_type, unsigned long, ...)' /tmp/ccytTZBu.o(.text+0x173): In function `init_unit_test_suite(int, char*)':

You need to link with the pre-built standalone library. Use either Jam with Boost.Build system to build the library or you could use your own make system. But in that case you will need to come up with makefile yourself. The framework doesn't need much special compilation flags. Consult docs and Jam for more details.

Yeah, the docs are quite explicit about the need to link with the libs. Your Makefile could be as simple as: CXXFLAGS= -I/usr/local/include LDFLAGS= -L/usr/local/lib -lboost_filesystem -lboost_program_options fubar: fubar.cpp $(CXX) $(CXXFLAGS) $(LDFLAGS) -o fubar fubar.cpp -- How many Vietnam vets does it take to screw in a light bulb?
