Porting a driver from SunOS 4.1 to Solaris 2.5

Porting a driver from SunOS 4.1 to Solaris 2.5

Post by Marc De Prete » Tue, 10 Mar 1998 04:00:00



Hi

Someone asked me if I can port a driver, developped on SunOS 4.1 (i
suppose it's Solaris 1) to Solaris 2.5 (i suppose it means SunOS 5.5).
I've got the full code, which is quit long (around 20 000 lines of C to
be ported). The driver has been developped has a module.

On another forum, someone told me that the main differences between
SunOSes is that SunOS 4 = BSD, and SunOS 5 : Sys V. If we want to do the
porting, we will have a well defined time frame, so I prefer think twice
before saying OK.

My question is : who has already done this (porting a module from sunos
4 to sunos 5) ? Was it tough ? Knowing that the code is heavily
commented, that the machine will be the same (same bus, same cpu, ....
it's just the OS that will be changed), what kind of surprise may I
expect ?

Can someone give me any clue/hints/comments ?

Thanks,

Marc

1. Porting from SunOS (4.1) to Solaris (SunOS 5.5.1)

Hi,
I am porting some code from SunOS 4.1 to SunOS 5.5.1 (Solaris)
I am getting following link errors on Solaris.
Even after adding "-lsocket -lnsl -lels -laio" libs on link line.
===================================================================
ild: (Performing full relink) arguments are inconsistent [...]
ild: (undefined symbol) sigsetmask -- referenced in the text segment of
../lib/SOLARIS//libqtools.a(emmMap.o)

===================================================================

also gives undefined symbols for sigsetmask and sigblock for several
other files.
How do I remove these errors?
Do I need to check for any libs on my solaris machine?
Thanks in advance,
Santosh
