Bug ID: 107233
Summary: gm2 build hardcodes python3
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: modula2
Assignee: gaius at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
Target Milestone: ---
Target: *-*-solaris2.11
When trying to build the current devel/modula-2 branch on Solaris 11.3/SPARC
(only tried on 11.4 before), it fails trying to execute python3
unconditionally:
python3 /vol/gcc/src/hg/master/modula-2/gcc/m2/tools-src/def2texi.py -b./
-f/vol/gcc/src/hg/master/modula-2/gcc/m2/gm2-libs/Builtins.def >
/var/gcc/modula-2/11.4-gcc-modula-2/gcc/m2/Builtins.texi
/bin/ksh: python3: not found
make[3]: *** [/vol/gcc/src/hg/master/modula-2/gcc/m2/Make-lang.in:167:
Builtins.texi-check] Error 127
This happens because Solaris 11.3, unlike 11.4, has no python3 command. It
only
provides python2.7 and python3.4.
I believe this could easily be fixed by using Automake's AM_PATH_PYTHON([3.0])
(or whatever minimal python 3.x version is required), substituting the
resulting
$PYTHON into Make-lang.in and the scripts that currently hardcode python3
instead.

Now fixed. configure.ac tests for python3 and Make-lang.in only invokes
python3 if it were found.

Confirmed on i386-pc-solaris2.11 (Solaris 11.3). However, I still think
using AM_PATH_PYTHON as I've suggested initially to handle systems that
*do* have Python 3, but by another name (python3.4 here). Right now,
only a couple of .texi files are missing, though, so the effect of
staying with you solution is minor. I don't know if this will change in
the future if more depends on a working Python 3 installation.
Thanks.
Rainer

ok, thanks for the suggestion. I've changed gcc/configure.ac to use
AM_PATH_PYTHON and AM_CONDITIONAL:
# Python3?
AM_PATH_PYTHON(,, [:])
AM_CONDITIONAL([HAVE_PYTHON], [test "$PYTHON" != :])

But wouldn't this pick up a version of python < 3.0 if nothing else is
present? If the python code inside gcc/m2 does require 3.x, shouldn't
this be
AM_PATH_PYTHON([3.0],, [:])
(or whatever is the minimum) instead?
