Possibly remind the reader/installer that when installing the 5.0 tools,
the "install all the patches" script on that CD (which the CD install
instructions assume that you run, of course) adds 107058-01 automatically.
I only /happened/ to catch the patch # scrolling by and /happened/ to
recall reading the specific.html blurb a month before.  I suspect some
people can get into problems this way.

I can submit bugs to Sun (we have a support contract and I have some spare
time), but I found out this week that the mailserver at work is on the ORBS
blacklist :-( so I've been holding off from joining the discussion until I
can actually send mail to these lists.  I will be more than willing to help
once I convince the mail admin...

Please pester Sun as much as you can concerning their broken patches resp.
tools.

We have had quite high a number of problem reports after the release of
GCC 2.95.x, many (if not most) of which were due to broken Sun tools.

Perhaps someone could also provide a detailed description resp. an example
of the way Sun make is broken?

There are known bugs in binutils 2.9.1 on Solaris/Sparc. Quite a few
Solaris/Sparc bugs have been fixed in binutils in cvs.

It has been a "known problem" for years. The _original_ problem 
was GNU ld not honouring LD_RUN_PATH nor -R or equivalent. 
IIRC the exact problem has varied over the years.

There was a version around binutils-2.8.? when it did work, but it was too 
hard for us to explain to the clueless that they needed to install 
new binutils and possibly re-build gcc. (Lots of comparitively clueless
want to build and use perl.)

Now that GNU ld actually gains something (at least for C++) it is 
worth taking the time to figure it out.

Copy to perl5-porters@perl.org too - at very least Configure will 
probably need tweaks to command line stuff.

Oh, thanks for following up, I might have forgotten to mention.

Since the last message, I sent in some patches to Perl so that it would
correctly detect what ld gcc 2.95.1 was using, and ended up looking at the
hints file in the development version of Perl.  Turns out that the problem
these days with GNU ld isn't a bug but rather a difference in behavior
between Solaris ld and GNU ld in how they add symbols to the dynamic
symbol table.  Passing -E to GNU ld is rumored to allow Perl to build
correctly.

(It's getting to be a full-time job just updating one's mental map of what
software packages work where!)

I've since moved on to other projects and probably won't have the time to
go back and check with GNU ld in the near future, but based on that (and
the report of Solaris fixes in the CVS tree), I'll give GNU ld another
shot on Solaris the next time I rebuild binutils and gcc.

I haven't, under the assumption that the hint file entry in Perl saying
that GNU ld wouldn't work meant that this was a known problem.  If people
think it would help, I can try it again in a few days and put together a
fuller problem report.  Perl makes extensive use of dynamically loaded
modules, and the symptom that I was seeing was that when all of Perl was
linked with GNU ld, it couldn't load the dynamic modules that it had just
built.

It might be the case that there were a couple of bugs, so providing some
new feedback that it still does not work could prove rather useful.

HJ Lu mentioned that the CVS versions of binutils have a couple of
SPARC-related issues fixed, perhaps you can give that a try?

(I don't have the URL, but I am sure someone on this list will provide
it.)

Thanks, HJ! I haved installed the patch below; it would be great if
someone would drop us a note once binutils have fixed these bugs in
an "official" release.
