[Bug libstdc++/32499] New: libstdc++ testsuite fails on platforms without ranlib

["gcc-bugzilla at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I noticed that the libstdc++ testsuite fails to run on mips-sgi-irix6.5 and
mips-sgi-irix5.3::

ERROR: tcl error sourcing
/vol/gcc/src/gcc-dist/libstdc++-v3/testsuite/libstdc++-abi/abi.exp.
ERROR: could not link libtestc++.a
    while executing
"error "could not link libtestc++.a""
    (procedure "v3-build_support" line 82)
    invoked from within
"v3-build_support"
    (file "/vol/gcc/src/gcc-dist/libstdc++-v3/testsuite/libstdc++-abi/abi.exp"
line 22)
    invoked from within
"source /vol/gcc/src/gcc-dist/libstdc++-v3/testsuite/libstdc++-abi/abi.exp"
    ("uplevel" body line 1)
    invoked from within
"uplevel #0 source
/vol/gcc/src/gcc-dist/libstdc++-v3/testsuite/libstdc++-abi/abi.exp"
    invoked from within
"catch "uplevel #0 source $test_file_name""

It turns out that this happens since the platform lacks ranlib, but
testsuite/lib/libstdc++.exp (v3-build_support) uses either
$RANLIB_FOR_TARGET or ranlib.  Of course, trying to execute a non-existant
command fails.

The toplevel Makefile only passes in RANLIB=:, not RANLIB_FOR_TARGET.

This was most likely introduced by this patch:

2007-03-15  Hans-Peter Nilsson  <hp@axis.com>

        * testsuite/lib/libstdc++.exp (v3-build_support) <ar>: If it
        exists, use env(AR_FOR_TARGET).  Log the command.
        <ranlib>: Similar.

Environment:
System: IRIX64 columba 6.5 07010238 IP27

------- Comment #1 from ro at techfak dot uni-bielefeld dot de  2007-06-25 15:23 -------
Fix:
This can be worked around by setting RANLIB_FOR_TARGET=: in the
environment, but this shouldn't be necessary.
