I can reproduce the
sed: 1: ""s/\*/\\\*/g"": invalid command code "
error with the minimum configure.ac which contains LT_LANG(C++)
which calls _LT_LANG_CXX_CONFIG,
which calls AC_LIBTOOL_PROG_LD_SHLIBS,
which calls AC_LIBTOOL_POSTDEP_PREDEP,
which has
# The `*' in the case matches for architectures that use `case' in
# $output_verbose_cmd can trigger glob expansion during the loop
# eval without this substitution.
output_verbose_link_cmd="`$echo \"X$output_verbose_link_cmd\" | $Xsed -e
\"$no_glob_subst\"`"
where
# Sed substitution to avoid accidental globbing in evaled expressions
no_glob_subst='s/\*/\\\*/g'
Before output_verbose_link_cmd is "no_globbed", its value is
$CC -shared $CFLAGS -v conftest.$objext 2>&1 | $GREP conftest.$objext | $SED -e
"s:-lgcc -lc -lgcc::"
The great part is this is a ksh quoting problem:
================= foo ==================
CC=cc
SED=sed
GREP=grep
echo=echo
Xsed='sed -e s/^X//'
no_glob_subst='s/\*/\\\*/g'
output_verbose_link_cmd="$CC -shared $CFLAGS -v conftest.$objext 2>&1 | $GREP
conftest.$objext | $SED -e \"s:-lgcc -lc -lgcc::\""
echo "output_cmd: ($output_verbose_link_cmd)"
output_verbose_link_cmd="`$echo \"X$output_verbose_link_cmd\" | $Xsed -e
\"$no_glob_subst\"`"
echo "output_cmd: ($output_verbose_link_cmd)"
========================================
% sh foo
output_cmd: (cc -shared -v conftest. 2>&1 | grep conftest. | sed -e "s:-lgcc
-lc -lgcc::")
output_cmd: (cc -shared -v conftest. 2>&1 | grep conftest. | sed -e "s:-lgcc
-lc -lgcc::")
% ksh foo
output_cmd: (cc -shared -v conftest. 2>&1 | grep conftest. | sed -e "s:-lgcc
-lc -lgcc::")
sed: 1: ""s/\*/\\\*/g"": invalid command code "
output_cmd: ()
Oh joy... (ksh version @(#)PD KSH v5.2.14 99/07/13.2)
Cheers,
