ax_python_config_var

AX_PYTHON_CONFIG_VAR:

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.

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.

Example:

  AX_PYTHON_CONFIG_VAR(LINKFORSHARED, PY_LFS)

AX_PYTHON_CONFIG_H:

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.

AX_PYTHON_MAKEFILE:

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.
