Yes, is seems "binutils 2.13" + "gcc 3.2" + "Solaris 8" => pile of crap.  I 
still haven't figured out which binutils will work.

I tried the Sun linker and assembler in "/usr/ccs/bin".  With them I can at 
least run a simple program, but now there are problems linking source files 
that use "std::basic_string<wchar_t>".

Hopefully "binutils 2.12.1" will do the trick.  If that doesn't work I'll go 
back to "binutils 2.11.2"; that worked well with "gcc 3.0.4".

I'm sure I'll get it going eventually.  I just found out I need another 
configure flag "--enable-cxx-flags="-fshort-wchar".  Thank you for your 
help.

Did you configure/build with binutils 2.13?  I recall reports that these
totally broke gcc 3.2.  I've personally avoided GNU binutils on Solaris 2,
and didn't ever have problems with this approach.

Do you have a simple testcase that fails for you?  Then please file a bug
(via gccbug) so this can be investigated.

This seems terribly wrong: the gcc/g++ defaults for wchar_t match what
Solaris 8 has in <iso/wchar_iso.h>, while the -fshort-wchar flag changes
wchar_t to short, creating an incompatibility with system functions.

Why do you think you need this?

[Almost too embarassed to share this tale...]

simple.  watch, learn, and weep (or laugh)

$ strip /tmp/gcc-install/usr/lib/gcc-lib/i686-pc-linux-gnu/3.0.4/crtbegin.o
etc.

Of course, linking in a stripped (now non-)relocatable object file is BAD.

The fix?  Don't strip.  Seems simple now, but I had a monster of a time
figuring it out in the first place.  Things got quite hairy for a while,
when I noticed that I had actually final-installed a nonworking gcc.  Lucky
I still had gcc2.7.2.3 around with which to bootstrap.

IOW very early in libgcc_s.so.1

A while back I almost lost my mind trying to figure out why my libgcc_s.so.1
segfaulted instantly (actually, anything compiled with the newly compiled
gcc-3.0.4).

It turns out that while installing the compiler, I had stripped crtstuff.

Again, you should provide a testcase showing what fails without the
--enable-cxx-flags="-fshort-wchar".  I'd expect that with this flag, a
testsuite run fails high and low.

> Also, I guess I don't know what system functions this would interfere with.

This seems somewhat fishy to me: consider the -fshort-wchar docs:

`-fshort-wchar'
     Override the underlying type for `wchar_t' to be `short unsigned
     int' instead of the default for the target.  This option is useful
     for building programs to run under WINE.

So this seems to have very limited use.  But this is probably something for
the language experts to comment upon.

Ah, I see it:

http://gcc.gnu.org/ml/gcc-bugs/2002-08/msg00348.html

Are you sure these are the 32 bit libraries?  I tried just moving them into 
local/lib, but libgcc_s.so.1 segfaults instantly.

I tried this:

int main(void)
{
  return 0;
}

When I debug it in gdb I get this:

This is a known problem: PR target/6668, but unfortunately still not fixed.

It's broken in the --disable-multilib case. It installs the 32-bit library
into sparcv9 and nothing into lib.

This came up on the gcc-help list a while back; sorry, I'd assumed a bug
had been filed. I had a quick look at mklibgcc at the time but I was
in over my head and too busy to chase it very far.

gcc 3.2 on Solaris 8 (libgcc_s.so problem)

[Anthony Feick]

GCC 3.2 on sparc Solaris 8 doesn't install libgcc_s.so.  It makes the 
library, but doesn't move it over.  When I copy it to the install directory, 
it seems to be broken:
