gen-classlist.sh problem while building gcc 4.2.4

gen-classlist.sh problem while building gcc 4.2.4

[David Eisner]

Still trying to build gcc-4.2.4 on a Solaris 9 box.  During stage 3, I
run into this problem:

cannes [lib]$ make
true
top_builddir=..
top_srcdir=../../../../../../gcc-4.2.4/libjava/classpath /bin/sh
./gen-classlist.sh standard
Adding java source files from srcdir
'../../../../../../gcc-4.2.4/libjava/classpath'.
Adding java source files from VM directory
/export/data/software/cradle/build/gcc/gcc-4.2.4/libjava
Adding java source files from VM directory
/export/data/software/cradle/build/gcc/objdir/sparc-sun-solaris2.9/sparcv9/libjava
./gen-classlist.sh: test: unknown operator -ef
make: *** [genclasses] Error 1

The problem appears to be that the built-in 'test'  operator in the
/bin/sh Bourne shell that ships with Solaris 9 doesn't understand the
-ef operator, though bash does:

cannes [lib]$ /bin/sh -c 'test foo -ef bar && echo same'
/bin/sh: test: unknown operator -ef
cannes [lib]$ /usr/bin/bash -c 'test foo -ef bar && echo same'
cannes [lib]$

I couldn't find this in the bug database.  Should I report it?

Workaround: in gen-classlist.sh, change
   if test ! "${top_builddir}" -ef
"../../../../../../gcc-4.2.4/libjava/classpath"; then
to
   if /usr/bin/test ! "${top_builddir}" -ef
"../../../../../../gcc-4.2.4/libjava/classpath"; then

By the way, I'm not sure why it's even building java.  I didn't
include java in the enabled languages when I ran configure.  I guess
it knows best.

This is <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25557>.
If this isn't a regression (which I'm not sure of), then I guess this
bug won't be fixed in the branch.

The relevant diff between branch-4_2 and branch-4_3 is this (which looks
a bit different from the patch proposed in that PR):

Try passing --enable-languages explicitly.

Thanks for finding that.  I had created a new bug
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37000), and I've now
marked it a duplicate.

It was recommended that I set CONFIG_SHELL to /bin/ksh, as recommended
in the build notes for Solaris, and that did the trick for me:

  http://gcc.gnu.org/install/specific.html#x-x-solaris2

I should have noticed that before.

I did.  Here's how i called configure:

CC="cc -xarch=v9 -xildoff" ../gcc-4.2.4/configure \
          --prefix=/data/software/devtools/gcc-4.3.1-sparc-sun-solaris2.9 \
          --enable-langues=c,c++,objc \
          --with-gmp=/data/software/devtools/gmp-4.2.1-sparc-sun-solaris2.9 \
          --with-mpfr=/data/software/devtools/mpfr-2.3.0-sparc-sun-solaris2.9

Strangely, though, when I look at config.status, I see this:

#! /bin/sh
# Generated automatically by configure.
# Run this file to recreate the current configuration.
# This directory was configured as follows,
# on host cannes.umd.edu:
#
# ../gcc-4.2.4/configure
--prefix=/data/software/devtools/gcc-4.3.1-sparc-sun-solaris2.9
--enable-langues=c,c++,objc
--with-gmp=/data/software/devtools/gmp-4.2.1-sparc-sun-solaris2.9
--with-mpfr=/data/software/devtools/mpfr-2.3.0-sparc-sun-solaris2.9
--enable-languages=c,c++,java,objc
#

I don't know why the extra --enable-languages switch was appended, and
this time with java included.

A kind soul pointed out that I typed "--enable-langues" and not
"--enable-languages".  I think I implicitly assumed the ./configure
script would complain about typos, but it's liberal about accepting
--enable-*, probably with good reason.

Apologies for the bother.
