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?

Thanks
HG

$ echo "void foo(){}" >/tmp/foo.c
$ /opt/SUNWspro/bin/cc -c -m64 foo.c -o /tmp/foo.o
$ file /tmp/foo.o
/tmp/foo.o:	ELF 64-bit LSB relocatable AMD64 Version 1
$ ls -lL /opt/SUNWspro/lib/amd64

I got the below output

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.

Try:

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

-m64 is used too with current Sun C compilers:

Hi jlliagre & hergp,

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