| 9 | # DESCRIPTION
|
|---|
| 10 | #
|
|---|
| 11 | # Test for the Boost C++ libraries of a particular version (or newer)
|
|---|
| 12 | #
|
|---|
| 13 | # If no path to the installed boost library is given the macro searchs
|
|---|
| 14 | # under /usr, /usr/local, /opt and /opt/local and evaluates the
|
|---|
| 15 | # $BOOST_ROOT environment variable. Further documentation is available at
|
|---|
| 16 | # <http://randspringer.de/boost/index.html>.
|
|---|
| 17 | #
|
|---|
| 18 | # This macro calls:
|
|---|
| 19 | #
|
|---|
| 20 | # AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
|
|---|
| 21 | #
|
|---|
| 22 | # And sets:
|
|---|
| 23 | #
|
|---|
| 24 | # HAVE_BOOST
