|
|---|
| 10 | dnl ROOT_PATH([MINIMUM-VERSION, [ACTION-IF-FOUND, [ACTION-IF-NOT-FOUND]]])
|
|---|
| 11 | dnl
|
|---|
| 12 | dnl Some examples:
|
|---|
| 13 | dnl
|
|---|
| 14 | dnl ROOT_PATH(3.03/05, , AC_MSG_ERROR(Your ROOT version is too old))
|
|---|
| 15 | dnl ROOT_PATH(, AC_DEFINE([HAVE_ROOT]))
|
|---|
| 16 | dnl
|
|---|
| 17 | dnl The macro defines the following substitution variables
|
|---|
| 18 | dnl
|
|---|
| 19 | dnl ROOTCONF full path to root-config
|
|---|
| 20 | dnl ROOTEXEC full path to root
|
|---|
| 21 | dnl ROOTCINT full path to rootcint
|
|---|
| 22 | dnl ROOTLIBDIR Where the ROOT libraries are
|
|---|
| 23 | dnl ROOTINCDIR Where the ROOT headers are
|
|---|
| 24 | dnl ROOTETCDIR Where the ROOT configuration is
|
|---|
| 25 | dnl ROOTCFLAGS Extra compiler flags
|
|---|
| 26 | dnl ROOTLIBS ROOT basic libraries
|
|---|
| 27 | dnl ROOTGLIBS ROOT basic + GUI libraries
|
|---|
| 28 | dnl ROOTAUXLIBS Auxilary libraries and linker flags for ROOT
|
|---|
| 29 | dnl ROOTAUXCFLAGS Auxilary compiler flags
|
|---|
| 30 | dnl ROOTRPATH Same as ROOTLIBDIR
|
|---|
| 31 | dnl
|
|---|
| 32 | dnl The macro will fail if root-config and rootcint isn't found.
