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.
