I use the Boost package provided by Ubuntu, so I haven't compiled them
myself. In that case the libraries are installed in /usr/include/boost/.

In ProbABEL's configure.ac I test for boost as follows (see the branch
at
https://r-forge.r-project.org/scm/viewvc.php/branches/ProbABEL-pvals/ProbABEL/?root=genabel):

----------------------------------------
if test "x$with_boost_math" != "xno"; then
    AC_MSG_NOTICE([building using the Boost Math library enabled])

    AC_ARG_WITH([boost-include-path],
        [AS_HELP_STRING([--with-boost-include-path],
          [location of the Boost headers, defaults to /usr/include/boost])],
        [CXXFLAGS+=" -I${withval}"
        CPPFLAGS+=" -I${withval}"],
        [CXXFLAGS+=' -I/usr/include/boost'
        CPPFLAGS+=' -I/usr/include/boost'])

    # Check for the Boost Math header files
    AC_CHECK_HEADERS([boost/math/distributions.hpp])

    if test x$ac_cv_header_boost_math_distributions_hpp = xno; then
      AC_MSG_ERROR([Could not find the Boost Math header files. Did \
you specify --with-boost-include-path correctly? Or use --without-boost \
to disable the calculation of p-values.])
    fi
else
   AC_MSG_NOTICE([not using the Boost Math libraries, so no p-values in
the \
output])
fi
AM_CONDITIONAL([WITH_BOOST_MATH], test "x$with_boost_math" != "xno")
----------------------------------------

This creates a variable WITH_BOOST_MATH that can be used in AutoMake's
Makefile.am files:
----------------------------------------
if WITH_BOOST_MATH
palinear_CXXFLAGS += -DWITH_BOOST_MATH
endif
----------------------------------------

And then in the .cpp files, for example:
----------------------------------------
#if WITH_BOOST_MATH
    std::vector<std::ostringstream *> pval;
#endif
----------------------------------------


Hope that helps.

Lennart.
