# hints/linux.sh
# Original version by rsanders
# Additional support by Kenneth Albanowski <kjahds@kjahds.com>
#
# ELF support by H.J. Lu <hjl@nynexst.com>
# Additional info from Nigel Head <nhead@ESOC.bitnet>
# and Kenneth Albanowski <kjahds@kjahds.com>
#
# Consolidated by Andy Dougherty <doughera@lafcol.lafayette.edu>
#
# Updated Thu Feb 8 11:56:10 EST 1996
# Add ability to use command-line overrides for optinal settings.
# perl goes into the /usr tree. See the Filesystem Standard
# available via anonymous FTP at tsx-11.mit.edu in
# /pub/linux/docs/linux-standards/fsstnd.
# Allow a command line override, e.g. Configure -Dprefix=/foo/bar
case "$prefix" in

# gcc-2.6.3 defines _G_HAVE_BOOL to 1, but doesn't actually supply bool.

You don't have an ELF gcc. I will use dld if possible. If you are
using a version of DLD earlier than 3.2.6, or don't have it at all, you
should probably upgrade. If you are forced to use 3.2.4, you should
uncomment a couple of lines in hints/linux.sh and restart Configure so
that shared libraries will be disallowed.

# These empty values are so that Configure doesn't put in the
# Linux ELF values.

ccflags="-DOVR_DBL_DIG=14 $ccflags"
so='sa'
dlext='o'
## If you are using DLD 3.2.4 which does not support shared libs,
## uncomment the next two lines:
#ldflags="-static"
#so='none'
fi
rm -f try.c a.out
if /bin/bash -c exit; then
echo You appear to have a working bash. Good.
else
cat << 'EOM'
Warning: it would appear you have a defective bash shell installed. This is
likely to give you a failure of op/exec test #5 during the test phase of the
build, Upgrading to a recent version (1.14.4 or later) should fix the
problem.

# In addition, on some systems there is a problem with perl and NDBM, which
# causes AnyDBM and NDBM_File to lock up. This is evidenced in the tests as
# AnyDBM just freezing. Currently we disable NDBM for all linux systems.
# If someone can suggest a more robust test, that would be appreciated.

# From: Jeffrey Friedl <jfriedl@nff.ncl.omron.co.jp>
#
# I tried compiling with DBM support and sure enough things locked up
# just as advertised. Checking into it, I found that the lockup was
# during the call to dbm_open. Not *in* dbm_open -- but between the call
# to and the jump into.
#
# To make a long story short, making sure that the *.a and *.sa pairs of
# /usr/lib/lib{m,db,gdbm}.{a,sa}
# were perfectly in sync took care of it.
#
# This will generate a harmless message:
# Hmm...You had some extra variables I don't know about...I'll try to keep 'em.
# Propagating recommended variable d_dbm_open
