Compiling with Oracle Solaris Studio

Use the -D_KERNEL option to indicate that this code defines a kernel module.

• If you are compiling for a 64-bit SPARC architecture using Sun Studio 9, Sun Studio 10, or Sun Studio 11, use the -xarch=v9 option:

  % cc -D_KERNEL -xarch=v9 -c mydriver.c % ld -r -o mydriver mydriver.o

  If you are compiling for a 64-bit SPARC architecture using Sun Studio 12, use the -m64 option:

  % cc -D_KERNEL -m64 -c mydriver.c % ld -r -o mydriver mydriver.o

• If you are compiling for a 64-bit x86 architecture using Sun Studio 10 or Sun Studio 11, use both the -xarch=amd64 option and the -xmodel=kernel option:

  % cc -D_KERNEL -xarch=amd64 -xmodel=kernel -c mydriver.c % ld -r -o mydriver mydriver.o

  If you are compiling for a 64-bit x86 architecture using Sun Studio 12, use the -m64 option, the -xarch=sse2a option, and the -xmodel=kernel option:

  % cc -D_KERNEL -m64 -xarch=sse2a -xmodel=kernel -c mydriver.c % ld -r -o mydriver mydriver.o

• If you are compiling for a 32-bit architecture, use the following build commands:

  % cc -D_KERNEL -c mydriver.c % ld -r -o mydriver mydriver.o

Sun Studio 9 does not support 64-bit x86 architectures. Use Sun Studio 10, Sun Studio 11, or Sun Studio 12 to compile and debug drivers for 64-bit x86 architectures.

For more information on compile and link options, see the Sun Studio Man Pages and the Sun Studio 12: C User’s Guide.
