[OpenIndiana-discuss] g++ 4.6 from SFE repository

[Ewald Ertl]

Hello,

I'm trying to compile a simple C++ file on my OpenIndiana 151a with
the g++ from the SFE repository.

root at solewer:/usr/gcc/4.6# g++ --version
g++ (GCC) 4.6.2
Copyright (C) 2011 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

But this results in a lot of errors during the assembly stage:
root at solewer:~# g++ a.cpp
Assembler: a.cpp
    "/var/tmp//cclAa4ot.s", line 80 : Syntax error
    Near line: "    .uleb128 .LLSDACSE549-.LLSDACSB549"
    "/var/tmp//cclAa4ot.s", line 82 : Syntax error
    Near line: "    .uleb128 .LEHB0-.LFB549"
    "/var/tmp//cclAa4ot.s", line 83 : Syntax error
    Near line: "    .uleb128 .LEHE0-.LEHB0"


With the g++ from /usr/sfw/bin ( pkg://openindiana.org/developer/gcc-3
)  the compilation succeeded.

I've now started with execsnoop to see whats happening:

g++ from the SFE repository uses the default assembler:
 UID    PID   PPID ARGS
    0   7755   7662 g++ a.cpp
    0   7756   7755
/usr/gcc/4.6/lib/gcc/i386-pc-solaris2.11/4.6.2/cc1plus -quiet a.cpp
-quiet -dum
    0   7758   7662 /usr/bin/hostname
    0   7757   7755 /usr/ccs/bin/as -s -o /var/tmp//ccYHayjp.o
/var/tmp//ccXHayjp.s

but using /usr/sfw/bin/g++ from (
pkg://openindiana.org/developer/gcc-3 ) the gcc  has its own assembler

    0   7762   7662 /usr/sfw/bin/g++ a.cpp
    0   7763   7762
/usr/sfw/libexec/gcc/i386-pc-solaris2.11/3.4.3/cc1plus -quiet a.cpp
-quiet -dum
    0   7764   7762 /usr/sfw/libexec/gcc/i386-pc-solaris2.11/3.4.3/as
--traditional-format -Qy -s -
    0   7765   7762
/usr/sfw/libexec/gcc/i386-pc-solaris2.11/3.4.3/collect2 -Y
P,/usr/ccs/lib:/lib:


Compiling a C file with  gcc works for both 4.6.2 and 3.4.3

Has anyone else problems?

Thanks for any help
