Warning in building a kernel
2007-12-25 8:14:00
I have the following message when a rebuild the kernel:
....
cc -sparc -c -O
-Dsun4c -DOASYS -DSUN4C_60 -DWINSVJ -DVDDRV -DASYNCHIO -DLWP -DVFSSTATS
-DRFS -DCRYPT -DTCPDEBUG -DIPCSHMEM -DIPCSEMAPHORE -DIPCMESSAGE -DSYSAUDIT
-DSYSACCT -DPCFS -DHSFS -DTMPFS -DTFS -DLOFS -DNFSSERVER -DNFSCLIENT -DUFS
-DQUOTA -DINET -DSHMMNI="100" -DSHMSIZE="8192" -DKERNEL -I. -I.. -I../..
..http://sun/kern_wrapxxx.c
"..http://sun/kern_wrapxxx.c", line 35: warning: illegal pointer combination
kern_wrapxxx.c has the following lines around line 35:
short *
slacc_u_ruid()
{
return (&u.u_ruid); <------- line 35
}
What is u.u_ruid? Does it hurt to use this newly built kernel?
Summary:
1) u.u_ruid is the real user id. Morrow Long suggested that the new
SunOS expects a long instead of a short for u_ruid. He also suggested
that change the return type of slacc_u_ruid() to long based on
preprocessor macro:
#ifdef U_RUID_32_BIT
long *
#else
short *
slacc_u_ruid()
{
...
}
2) Everyon says that it does not hurt to use the new kernel. Some says
that he's been seeing this warning message since SunOS 4.0.3.

BTW, to B.Rea, it was an unintentional pun for "Thanks for any pointers".
