Building Samba 3.2.0 on Solaris with Sun compiler

[David Eisner-2]

I was able to build Samba 3.0.x under Solaris 10 using the Sun Studio
compiler (cc) and the Solaris ld (/usr/ccs/bin/ld) that it uses.

Trying to build Samba 3.2.0, however, I immediately run into a problem
where the build process assumes the linker understands
"--version-script", which is specific to the GNU linker:

  Linking shared library bin/libtalloc.so
  /usr/ccs/bin/ld: illegal option -- version-script
  usage: ld [-6:abc:d:e:f:h:il:mo:p:rstu:z:B:CD:F:GI:L:M:N:P:Q:R:S:VY:?] file(s)
          [-64]           enforce a 64-bit link-edit

Is this a bug?

Thanks.

-David

Still wondering:  Is building with cc (as opposed to gcc) on Solaris
10 supported with Samba 3.2.0?

Thanks again.

Should be, sure. The build farm runs some hosts this way.

When I try to build with cc, it dies almost immediately with this:

   Linking shared library bin/libtalloc.so
   /usr/ccs/bin/ld: illegal option -- version-script
  usage: ld [-6:abc:d:e:f:h:il:mo:p:rstu:z:B:CD:F:GI:L:M:N:P:Q:R:S:VY:?] file(s)
          [-64]           enforce a 64-bit link-edit
          [-a]            create an absolute file
          [-b]            do not do special PIC relocations in a.out

.. and so on.

The problem is that the Solaris ld does not understand
--version-script: that's specific to the GNU linker.  Looking in the
Makefile, I find the problem here:

   ## Dynamic shared libraries build settings
   DSO_EXPORTS_CMD=-Wl,--version-script,$(srcdir)/exports/`basename $@
| sed 's/so$$/syms/'`

This is hard-coded into Makefile.in; it's not generated by the
configure script.  Unless I'm missing something (which is quite
possible), I don't see how this could work with the Solaris linker.

Thanks again for your help.

Ok, possibly we have the Solaris compiler but a GNU linker
in the build farm machines. Hmmm. Sorry, I don't have time
right now to fix this really, hunting a SMB signing bug in
3.2 :-(

Correction: The DSO_EXPORTS_CMD is hardcoded into Makefile.in, but
DSO_EXPORTS, which is what is used in the make target, comes from
configure.  If the Solaris ld is found in the PATH before the GNU ld
at configure time, there won't be any problems because the DSO_EXPORTS
macro won't be set to the value of DSO_EXPORTS_CMD.

The linker used is a function of the compiler, not the user's PATH,
but I'm not sure what the best fix is.  Maybe a --without-gnu-ld
option ?

Solaris 10 comes with gcc in /usr/sfw/bin

% gcc -v
Reading specs from /usr/sfw/lib/gcc/sparc-sun-solaris2.10/3.4.3/specs
Configured with: /sfw10/builds/build/sfw10-patch/usr/src/cmd/gcc/gcc-3.4.3/configure --prefix=/usr/sfw --with-as=/usr/ccs/bin/as --without-gnu-as --with-ld=/usr/ccs/bin/ld --without-gnu-ld
--enable-languages=c,c++ --enable-shared
Thread model: posix
gcc version 3.4.3 (csl-sol210-3_4-branch+sol_rpath)

The configure could grep for --without-gnu-ld`

I know.  But I was only able to get certain needed packages (looking
through notes ... )  -- I could only get heimdal to build with cc, but
not gcc.

In any case, it's nice that samba <= 3.0.x was not GNU toolchain
specific, and it appears that there's no reason 3.2.0 has to be,
either.

Another thing to consider is that Sun does a fair amount of trumpeting
about its compiler performance. I don't know what difference that tends
to make as far as Samba is concerned, but if it does make a difference,
it'd be nice to use the best compiler for the job (regardless of whether
GCC is available on that platform, which it tends to always be, and now
especially that the Sun compiler is free).
