Description

<p>
AX_PYTHON_CONFIG_VAR:
</p>
<p>
Using the Python module distutils.sysconfig[1], return a Python
configuration variable. PYTHON_VARIABLE is the name of the variable to
request from Python, and SHELL_VARIABLE is the name of the shell variable
into which the results should be deposited. If SHELL_VARIABLE is not
specified, the macro wil prefix PY_ to the PYTHON_VARIABLE, e.g., LIBS
-> PY_LIBS.
</p>
<p>
SHELL_VARIABLE is AC_SUBST'd. No action is taken if an error occurs. Note
if $PYTHON is not set, AC_CHECK_PROG(PYTHON, python, python) will be run.
</p>
<p>
Example:
</p>
<pre>
AX_PYTHON_CONFIG_VAR(LINKFORSHARED, PY_LFS)
</pre>
<p>
AX_PYTHON_CONFIG_H:
</p>
<p>
Using the Python module distutils.sysconfig[1], put the full pathname of
the config.h file used to compile Python into the shell variable
PY_CONFIG_H. PY_CONFIG_H is AC_SUBST'd. Note if $PYTHON is not set,
AC_CHECK_PROG(PYTHON, python, python) will be run.
</p>
<p>
AX_PYTHON_MAKEFILE:
</p>
<p>
Using the Python module distutils.sysconfig[1], put the full pathname of
the Makefile file used to compile Python into the shell variable
PY_MAKEFILE. PY_MAKEFILE is AC_SUBST'd. Note if $PYTHON is not set,
AC_CHECK_PROG(PYTHON, python, python) will be run.
