I've been using this linker line so far,

Upon your suggestion I modified this to
ld -dy -N driver2 -N misc/scsi -r driver2.o -o driver2
That looks bogus.
I think you want
ld -dy -N drv/somedriver -N misc/scsi -r driver2.o driver2
(Note that drv/somedriver would need to be installed in
/kernel/drv/amd64/ -- assuming you had an amd64 machine. On SPARC it
would be /kernel/drv/sparcv9/ and on 32-bit x86 just /kernel/drv/)
The misc/scsi module is found in /kernel/misc/{sparcv9,amd64,}/scsi
It should be present. Of course, if you're not using misc/scsi (i.e.
the SCSA framework), then you can drop the reference to above it!

In spite of this I'm getting errors after loading the driver. It isn't able to
attach because the scsi symbols aren't being resolved.
Any other tricks? Is misc/scsi supposed to be in the /kernel/drv directory or
something? Because I don't have it there.
Regards,
Bhaskar.

Subject: Re: [osol-code] Exporting solaris symbols from driver!
Hi I have two loadable modules and one of them depends on the other for some
symbols. I'm using
ld -N driver1 -o driver2 driver2.o
to resolve the symbol, but when I do so I'm unable to attach driver2 because it
is unable to resol
ve symbols for scsi_hba_tran_alloc etc. and related API's exported by the
transport layer.
Is there a way to export symbols from one module globally in solaris?
You'll need to link with the other device driver:
ld -dy -Nmisc/scsi
-dy - force dynamic linking
-Nmisc/scsi - add "misc/scsi" as a dependency
