Hi All,
When trying to compile a kernel for my 8 cpu DELL 8450's I recieve an extremly puzzling error, I get a bunch of errors when compiling a kernel that has the following options in it...
options WITNESS
options NETSMB
options NETSMBCRYPTO
options LIBMCHAIN
options LIBICONV
options PAE
options SMP options APIC_IO
Without PAE SMP or APIC_IO the kernel will compile fine. With these
options I get the following error when compiling the sym scsi driver.
cc -c -O -pipe -march=pentium3 -Wall -Wredundant-decls -Wnested-externs
-Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline
-Wcast-qual -fformat-extensions -std=c99 -nostdinc -I- -I. -I../../..
-I../../../dev -I../../../contrib/dev/acpica -I../../../contrib/ipfilter
-D_KERNEL -include opt_global.h -fno-common -mno-align-long-strings
-mpreferred-stack-boundary=2 -ffreestanding -Werror ../../../dev/sym/sym_hipd.c
cc1: warnings being treated as errors
../../../dev/sym/sym_hipd.c: In function `sym_setup_data_and_start':
../../../dev/sym/sym_hipd.c:8146: warning: cast from pointer to integer
of different size
*** Error code 1
This is rather unfortunate as the only disks I have run off this controller. I've found that it does compile with the ahc driver but even then some usb stuff needs removing.
Does anyone have any insight into this and what I can do to get it fixed.
Cheers,
The key kere is likely PAE, not APIC_IO, as PAE changes the size of some data types. The USB problem is known. The sym problem looks to be harmless assuming that the warning you got is the only one that is emitted. However, it appears that it was never certified as being ready for PAE. If you're adventurous, you can try compiling and loading it as a module (warnings when compiling modules are not fatal like they are in when compiling the kernel).
If there are more errors/warning that what you list, I'd be interested in seeing them.
