configure.ac: restore support for older automakes

[tschoonj]

Should fix the syntax errors seen when running configure generated with CentOS 6' autotools.

Hm, indien met PKG_CONFIG=/usr/bin/pkg-config runt het inderdaad de configure maar nu krijg ik een probleem dat make check faalt door:

Traceback (most recent call last): File "../../tests/python.py", line 2, in <module> import polycap ImportError: /home/ptack/poly_raytrace/build/src/.libs/libpolycap.so.0: undefined symbol: GOMP_parallel FAIL: python.sh 1 of 7 tests failed

Hey Pieter,

Heb het probleem opgelost door nieuwe versie van autotools te installeren in anaconda.

Doe autoreconf -fi .. en doe daarna make clean, ../configure plus opties, make, make check

[PieterTack]

Oke, thanks! Dit blijkt te werken.

Hij geeft precies wel enkele vreemde opmerkingen over configure.ac bij make: configure.ac:25: warning: AC_LANG_CONFTEST: no AC_LANG_SOURCE call detected in body en ../../lib/autoconf/lang.m4:193: AC_LANG_CONFTEST is expanded from... e.d.

Bij make check runt hij alles, en hij passed 6 tests. Vreemde is dat ik dacht dat met de python tests er 7 waren, dus die slaat hij over of ...?

[tschoonj]

Hij zal alleen maar de python test draaien als de optionele python bindings ook effectief gecompileerd geweest zijn.

Kijk eens naar de output van configure: is er ergens een probleem in het stuk waar hij de beschikbaarheid van python en cython nagaat?

[PieterTack]

Hm, kvind precies nergens vermelding van python of cython :s

Ok, ik zie wat er gebeurd is: uw branch is gemaakt voordat ik mijn python branch heb gemerged.

Doe het volgende:

# save al uw bestanden en exit vi
git stash
git fetch origin
git rebase origin/master # normaal gezien zouden er hier geen problemen mogen zijn, indien zo stop en toon mij de error messages
git stash pop
# doe verder uw werk en commit wanneer nodig
git push -f
