| 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 |
|---|
