After I tried to build libabigail on Debian, I realized the detection of python modules wasn't that great. The koji module wasn't present and yet the detection system tried to launch fedabipkgdiff regression tests. Woops. I was thinking about coming up with something easier to to update to add new modules to check for anyway, so I just dived in. I came up with a new autoconf macro of my own, AX_CHECK_PYTHON_MODULES, that lets you check for the presence of several python modules at once. This is more handy than having to call AX_PYTHON_MODULE for each module we want to detect. This fixes the detection issue I found and simplifies configure.ac. * configure.ac: Include autoconf-archive/ax_check_python_modules.m4 rather than autoconf-archive/ax_python_module.m4. Use AX_CHECK_PYTHON_MODULES rather than AX_PYTHON_MODULE. * Makefile.am: Add the new file autoconf-archive/ax_check_python_modules.m4 to source distribution and remove the older autoconf-archive/ax_python_module.m4 one. * autoconf-archive/ax_check_python_modules.m4: New file. * autoconf-archive/ax_python_module.m4: Remove.

# SYNOPSIS
|
|
#
|
|
# AX_CHECK_PYTHON_MODULE(MODNAME,
|
|
# PYTHON,
|
|
# ACTION-IF-FOUND,
|
|
# ACTION-IF-NOT-FOUND)
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Check that a python module is present on the system.
|
|
#
|
|
# MODNAME is the name of the python module to check for.
|
|
#
|
|
# PYTHON is either python2 or python3. It's the python interpreter
|
|
# to use. By default, this is python3.
|
|
#
|
|
# If the module MODNAME is found, the shell variable
|
|
# HAVE_PYMOD_MODNAME is set to 'yes' and ACTION-IF_FOUND is
|
|
# evaluated. Otherwise the shell variable HAVE_PYMOD_MODNAME is set
|
|
# to 'no' and ACTION-IF-NOT-FOUND is evaluated.
|
|
#
|
|
# Note that this macro was inspired from the ax_python_module.m4
|
|
# at
|
|
# http://www.gnu.org/software/autoconf-archive/ax_python_module.html.

|
|
# DESCRIPTION
|
|
#
|
|
# Checks that a set of Python modules are present on the system.
|
|
#
|
|
# MODLIST is a white space separated list of python modules to check
|
|
# for.
|
|
#
|
|
# PYTHON is either python2 or python3. It's the name of the python
|
|
# interpreter to use to perform the checking. By default, uses
|
|
# python3.
|
|
#
|
|
# If there is a module from MODLIST that is not found the execution
|
|
# of the test stops and ACTION-IF-NOT-FOUND is evaluated.
|
|
# Otherwise, if all modules are found, ACTION-IF-FOUND is evaluated.
