Compiler - 32bit or 64bit?

Hi Gurus,

I need to check whether the compiler installed in my system supports 64bit compilation.

Server - Sun fire v490
OS - Solaris 5.9
Processor - Sparcv9 (64bit)
Install Directory - /opt/SUNWSpro
Compiler Model - Sun Forte C Compiler.

My development team is claiming that there are no files in /opt/SUNWspro/bin/sparcv9 directory.
Hence it doesn't support 64bit.

Can somebody help me out?

I got the below output

[!]root: /opt/SUNWspro/bin/cc -c -m64 /tmp/foo.c -o /tmp/foo.o
cc: Warning: illegal option -m64

Old compiler releases were requiring a different option, try:
/opt/SUNWspro/bin/cc -c -xarch=v9 foo.c -o /tmp/foo.o
file /tmp/foo.o

-m64 ist the gcc option for 64 bit. The corresponding option for the Sun Studio compiler is -xarch=v9.

/opt/SUNWspro/bin/cc -c -xarch=v9 foo.c -o /tmp/foo.o

-m64 is used too with current Sun C compilers:

The way to specify compilation of a 32-bit or 64-bit binary has changed in this release. The -xarch option no longer carries an implicit memory model, 32-bit
ILP32 or 64-bit LP64, with each definition, and is now used only to specify the instruction set of the target processor.

Use the new -m32 and -m64 options to specify the memory model of the target compilation.

Hi jlliagre & hergp,

I got the below output. Can i conclude that the compiler supports 64bit compilation?

[!]root: /opt/SUNWspro/bin/cc -c -xarch=v9 /tmp/foo.c -o /tmp/foo.o
 @ /
[!]root: file /tmp/foo.o
/tmp/foo.o:     ELF 64-bit MSB relocatable SPARCV9 Version 1
 @ /

Hi Jlliagre and hgerp,

I meant to say, i am concluding that it is supporting 64bit compilation....Thanks for your valuable inputs.
