9 | # DESCRIPTION |
---|
10 | # |
---|
11 | # Makes sure that python supports the version indicated. If true the shell |
---|
12 | # commands in ACTION-IF-TRUE are executed. If not the shell commands in |
---|
13 | # ACTION-IF-FALSE are run. Note if $PYTHON is not set (for example by |
---|
14 | # running AC_CHECK_PROG or AC_PATH_PROG) the macro will fail. |
---|
15 | # |
---|
16 | # Example: |
---|
17 | # |
---|
18 | # AC_PATH_PROG([PYTHON],[python]) |
---|
19 | # AX_PROG_PYTHON_VERSION([2.4.4],[ ... ],[ ... ]) |
---|
20 | # |
---|
21 | # This will check to make sure that the python you have supports at least |
---|
22 | # version 2.4.4. |
---|
23 | # |
---|
24 | # NOTE: This macro uses the $PYTHON variable to perform the check. |
---|
25 | # AX_WITH_PYTHON can be used to set that variable prior to running this |
---|
26 | # macro. The $PYTHON_VERSION variable will be valorized with the detected |
---|
27 | # version. |
