           Summary: gcc-4.5.2 fails to build on Solaris 10 i386
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: yuri@tsoft.com


I downloaded gcc-core-4.5.2 and gcc-g++-4.5.2, configured with command:
../src/configure --with-gmp=/opt/local --with-mpfr=/opt/local
--with-mpc=/opt/local --prefix=/opt/local/gcc/4.5.2
Current binutils is in path.

This is an error I am getting after a while:

Its strange that there is an option -m64 that appears in the command line.

Not really because i386-solaris is a multi-arch target which includes amd64
too.  Can you attach config.log from
/tmp/gcc-build/4.5.2/bld/i386-pc-solaris2.10/amd64/libgcc ?

Assembler complains on -xarch option.
/opt/local/bin/as: unrecognized option `-xarch=generic64'

But '/opt/local/bin/as --help' doeasn't list -xarch as the valid option. It has
-march option.

Passing --with-gnu-as option to configure fixes the problem.
But why can't configure detect this by itself? GNU as has --version which
clearly says that its GNU assembler. And original Solaris as doesn't have
--version option.

--with-gnu-as lets gcc build to succeed.
But resulting g++ has the problem on all c++ modules:

Which is why it's recommended in the docs:
http://gcc.gnu.org/install/specific.html#ix86-x-solaris210

Please try using the suggested configuration

Actually g++ produces the correct assembler file, but still calls original Sun
assembler /usr/ccs/bin/as instead of the GNU one from the path, regardless of
the option --with-gnu-as passed to gcc configure.

Removing /usr/ccs/bin/as fixes the problem.

So there are two issues with gcc-4.5.2 on Solaris:
1. Inability to detect GNU assembler in path (unwarranted requirement to pass
--with-gnu-as). Broken build when either no GNU assembler in path or no option
--with-gnu-as passed.
2. GNU assembler from path isn't used by g++, causing Sun assembler to fail on
GNU-formatted assembler file.

There is nothing in these recommendations that configure can't do by itself.
Please update configure so that all users don't have to stumble upon the same
things over and over.

well if you don't want a working compiler feel free to ignore the docs and
refuse to try the options that might help

patches to configure are welcome.

I didn't refuse to try anything, I already got the working compiler.
I have suggested the improvement of configure to avoid further user confusion.

This works as designed.  If you don't specify --with-as=xxx at configure time,
the compiler is configured to pick whatever assembler it finds at run time.  On
Solaris, the default is the Sun assembler.

Likewise.  --with-gnu-as doesn't mean "pick the GNU assembler", it means that
the default assembler GCC will find is the GNU assembler.
