The hints/solaris_2.sh file that comes with perl5.005_03 attempts to
determine whether the ld being used is the Solaris version or the GNU
version. It does this by compiling a test program with the "-v"
switch, and sorting through the output for a line of the form​:

/full/path/to/ld [arguments]

The exact test is​:

  myld=`echo $verbose| grep ld | awk '/\/ld/ {print $1}'`
  # This assumes that gcc's output will not change, and that
  # /full/path/to/ld will be the first word of the output.

These assumptions are now incorrect. As of at least gcc version
2.95.2 (and probably earlier versions), "gcc -v" does *not* show the
full command line used to invoke ld; the only output which appears is
the output from "ld -V" itself, which is of the form​:

  ld​: Software Generation Utilities - Solaris/ELF (3.0)

In the above command pipeline, the "awk" command returns nothing, so
$myld gets set to an empty string, which causes the if-then-else
conditional to take the wrong path​:

  if $myld -V 2>&1 | grep "ld​: Software Generation Utilities" >/dev/null 2>&1; then
  cat <<END >&2

  Aha. You're using egcs and /usr/ccs/bin/ld.

  END

  else
  cat <<END >&2

  NOTE​: You are using GNU ld(1). GNU ld(1) will not build Perl.
  I'm arranging to use /usr/ccs/bin/ld by including -B/usr/ccs/bin/
  in your ${cc​:-cc} command. (Note that the trailing "/" is required.)

  END
  cc="${cc​:-cc} -B/usr/ccs/bin/"
  fi

The end result is that when Configure is run, it erroneously detects
GNU ld, and adds "-B/usr/ccs/bin" to the arguments passed to the C
compiler. While the "-B/usr/ccs/bin" is probably harmless, detecting
GNU ld when GNU ld does not exist on the system is bogus, and should
be fixed.

The follow patch modifies the ld test as follows​: if /full/path/to/ld
was not found in the output of "gcc -v", instead look for the Solaris
"ld​: Software Generation Utilities" magic string directly in the
"gcc -v" output itself; if that string is found, assume that gcc
invokes /usr/ccs/bin/ld. If a /full/path/to/ld was found in the
output of "gcc -v", invoke /full/path/to/ld with -V, and again check
the output for the "ld​: Software Generation Utilities" string.

James

This should be fixed in the development versions. Please try
5.005_63 and let us know how it fares.
