# SYNOPSIS
|
||||
#
|
||||
# AX_PYTHON
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# This macro does a complete Python development environment check.
|
||||
#
|
||||
# It recurses through several python versions (from 2.1 to 2.6 in this
|
||||
# version), looking for an executable. When it finds an executable, it
|
||||
# looks to find the header files and library.
|
||||
#
|
||||
# It sets PYTHON_BIN to the name of the python executable,
|
||||
# PYTHON_INCLUDE_DIR to the directory holding the header files, and
|
||||
# PYTHON_LIB to the name of the Python library.
|
||||
#
|
||||
# This macro calls AC_SUBST on PYTHON_BIN (via AC_CHECK_PROG),
|
||||
# PYTHON_INCLUDE_DIR and PYTHON_LIB.
