It has to do, obviously, with this function in libtool:

 1070	# func_show_eval cmd [fail_exp]
 1071	# Unless opt_silent is true, then output CMD.  Then, if opt_dryrun is
 1072	# not true, evaluate CMD.  If the evaluation of CMD fails, and FAIL_EXP
 1073	# is given, then evaluate it.
 1074	func_show_eval ()
 1075	{
 1076	    my_cmd="$1"
 1077	    my_fail_exp="${2-:}"
 1078	
 1079	    ${opt_silent-false} || {
 1080	      func_quote_for_expand "$my_cmd"
 1081	      eval "func_echo $func_quote_for_expand_result"
 1082	    }
 1083	
 1084	    if ${opt_dry_run-false}; then :; else
 1085	      eval "$my_cmd"
 1086	      my_status=$?
 1087	      if test "$my_status" -eq 0; then :; else
 1088		eval "(exit $my_status); $my_fail_exp"
 1089	      fi
 1090	    fi
 1091	}

but I have no idea how to test libtool, I even do not understand how the text is output… But it's obvious that this is being evaluated:

  407		# The commands to list exported symbols.
  408		export_symbols_cmds="\$NM \$libobjs \$convenience | \$global_symbol_pipe | \$SED 's/.* //' | sort | uniq > \$export_symbols"

And $global_symbol_pipe is defined as:

  172		# Take the output of nm and produce a listing of raw symbols and C names.
  173		global_symbol_pipe=""

So defining export_symbols_cmds as

  407		# The commands to list exported symbols.
  408		export_symbols_cmds="\$NM \$libobjs \$convenience | \$SED 's/.* //' | sort | uniq > \$export_symbols"

should work properly.

It's the first time that this shell script is used to link an executable – and it fails at once…

Proposed patch to libtool

[ballapete (Peter "Pete" Dyballa)]

Libtool is created by configure, so it can't be patched this usual way… Should m4/libtool.m4 be patched instead?

Well no. If global_symbol_pipe is empty, then the command being evaluated is:

export_symbols_cmds="$NM $libobjs $convenience | | $SED 's/.* //' | sort | uniq > $export_symbols"

The double pipe is what leads to the error message about the unexpected pipe symbol. I would say it was never intended for global_symbol_pipe to be empty, and the fact that global_symbol_pipe is empty in your case is what needs to be fixed.

This problem was ​described on the libtool mailing list before. It seems to be a problem with nm, and that the configure script does not exit after detecting nm's failure to parse the compiler's output.

[jeremyhu (Jeremy Huddleston Sequoia)]

It is not a problem with nm. It's not nm's fault that it's being fed into a buggy command line.

The bug is that global_symbol_pipe is empty. Why is that the case?

[jeremyhu (Jeremy Huddleston Sequoia)]

librsvg was configured with libtool 2.4.2. I wonder if this has been fixed at some point upstream. If you autoreconf, does it address the issue?

[jeremyhu (Jeremy Huddleston Sequoia)]

Oh wait... we do autoreconf... so no.

[jeremyhu (Jeremy Huddleston Sequoia)]

FWIW, I've got:

# Take the output of nm and produce a listing of raw symbols and C names.
global_symbol_pipe="sed -n -e 's/^.*[    ]\\([BCDEGRST][BCDEGRST]*\\)[   ][      ]*_\\([_A-Za-z][_A-Za-z0-9]*\\)\$/\\1 _\\2 \\2/p' | sed '/ __gnu_lto/d'"

On PPC Tiger, Mac OS X 10.4.11, I have the same problem.

If it's true that a misconfigured nm produces this fault, then /usb/bin/nm should be used instead of /opt/local/bin/nm, which comes from LLVM version 3.4.2. Invoking configure on the command line this nm produces a clear failure:

+ printf '%s\n' 'configure:7787: result: failed'

Setting NM=/usr/bin/nm seems to bring more success:

+ printf '%s\n' 'configure:7790: result: ok'

It seems to produce this value: lt_cv_sys_global_symbol_pipe='sed -n -e '\''s/^.*[ ]\([BCDEGRST][BCDEGRST]*\)[ ][ ]*_\([_A-Za-z][_A-Za-z0-9]*\)$/\1 _\2 \2/p'\'' | sed '\''/ __gnu_lto/d'\'''

[ballapete (Peter "Pete" Dyballa)]

On PPC Tiger it helps to add to the configure.args in Portfile the line

lt_cv_path_NM=/usr/bin/nm

and the link command now works:

The port finally built and was installed.

I think the cause of this event is that I fiddled with port select --set and set values for clang and llvm since I had finally working versions of them, needed for some other port(s)…

[ballapete (Peter "Pete" Dyballa)]

And the upgrade of ImageMagick fails due to the same reason… I think the next time, in four weeks, in August, I'll try with Clang and llvm 3.3 – I think this was the previous working setting.

[jeremyhu (Jeremy Huddleston Sequoia)]

Ok, I think r150060 should help you out.

[jeremyhu (Jeremy Huddleston Sequoia)]

(leaving this open to track a fix in libtool)

which was filed as #51819, though that's on El Capitan.

[ballapete (Peter "Pete" Dyballa)]

librsvg @2.40.20_5+viewer is installed. Before librsvg @2.40.20_3+viewer and librsvg @2.40.20_4+viewer were installed, built with ibtool @2.4.6, so the issue was solved and this ticket can be closed now.
