Hi,
On i686-darwin10, using libtool-2.4.2, I see the following occur:
$ make libhacktcommon.la
/bin/sh ../libtool --tag=CXX --mode=link ccache g++ -pipe -ansi
-pedantic-errors -Wold-style-cast -Woverloaded-virtual -W -Wextra -Wall

Object/common/.libs/dump_flags.o common/.libs/config.o

libtool: link: ranlib .libs/libhacktcommon.a
libtool: link: rm -fr .libs/libhacktcommon.lax
libtool: link: ( cd ".libs" && rm -f "libhacktcommon.la" && ln -s
"../libhacktcommon.la" "libhacktcommon.la" )
I get this funny message about tr usage.
The exit status is 0, so it thinks nothing went wrong, but the resulting
libhacktcommon.la shows:
---------- 8< snip ----------
# Libraries that this one depends upon.
dependency_libs=' -L/sw/lib'
---------- snip 8< ----------
with no mention of libltdl.
in Makefile.am, I have:
---------- 8< snip ----------
# convenience libraries
noinst_LTLIBRARIES = ... \
libhacktcommon.la
libhacktcommon_la_SOURCES = ...
libhacktcommon_la_LIBADD = $(LIBLTDL)
---------- snip 8< ----------
where LIBLTDL happens to be (in this case):
LIBLTDL = ${top_build_prefix}libltdl/libltdlc.la
=============== cat libltdlc.la ====================

=============== end of libltdlc.la ===================
Looks normal to me.
The only occurrences of 'tr' I see in the libtool script are:
---------- 8< snip ----------
# turn spaces into newlines.
SP2NL="tr "
# turn newlines into spaces.
NL2SP="tr ^M
"
---------- snip 8< ----------
SP2NL looks weird to me.
My tr is /usr/bin/tr (darwin10).
$(top_srcdir)/configure shows:
---------- 8< snip ----------
# test EBCDIC or ASCII
case `echo X|tr X '\101'` in
A) # ASCII based system
# \n is not interpreted correctly by Solaris 8 /usr/ucb/tr
lt_SP2NL='tr \040 \012'
lt_NL2SP='tr \015\012 \040\040'
;;
*) # EBCDIC based system
lt_SP2NL='tr \100 \n'
lt_NL2SP='tr \r\n \100\100'
;;
esac
---------- snip 8< ----------
coming from some libtool m4 macro, I assume?
Did something go wrong with SP2NL?
Here's a --debug trace of the above command:
---------- 8< snip ----------

usage: tr [-Ccsu] string1 string2
tr [-Ccu] -d string1
tr [-Ccu] -s string1
tr [-Ccu] -ds string1 string2
---------- snip 8< ----------
Looks like tr (piped) is only getting one argument.
If I try this on the command line (escaping $):
fang> tr \$'\r'
usage: tr [-Ccsu] string1 string2
tr [-Ccu] -d string1
tr [-Ccu] -s string1
tr [-Ccu] -ds string1 string2
I get the usage message, and an exit status of 1.
I don't see a set -o pipefail in the script so the overall exit status of
the libtool script is still 0.
Any idea what exactly went wrong?
Can you suggest a workaround?
Thanks for any help.
Fang
