There's a slight dependency issue with the new CONFIG_S[GDTR]_EXTRA_DEVS defines in the scsi stuff...
check it: [make modules...]
ld -m elf_i386 -r -o sr_mod.o sr.o sr_ioctl.o sr_vendor.o gcc -D__KERNEL__ -I/usr/src/linux/include -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -fno-strict-aliasing -pipe -mpreferred-stack-boundary=2 -DCPU=586 -march=k6 -DMODULE -c -o sg.o sg.c sg.c: In function `sg_init': sg.c:1092: `CONFIG_SD_EXTRA_DEVS' undeclared (first use in this function) sg.c:1092: (Each undeclared identifier is reported only once sg.c:1092: for each function it appears in.) sg.c:1073: warning: `size' might be used uninitialized in this function make[2]: *** [sg.o] Error 1 make[2]: Leaving directory `/usr/src/linux-2.3.44/drivers/scsi' make[1]: *** [_modsubdir_scsi] Error 2 make[1]: Leaving directory `/usr/src/linux-2.3.44/drivers' make: *** [_mod_drivers] Error 2
Ok, well let's take a look at line 1092 in sg.c in .../drivers/scsi/...
[sg.c] 1090: SCSI_LOG_TIMEOUT(3, printk("sg_init\n")); 1091: size = sizeof(Sg_device) * 1092: (sg_template.dev_noticed + SG_EXTRA_DEVS); 1093: sg_dev_arr = (Sg_device *)kmalloc(size, GFP_ATOMIC); 1094: memset(sg_dev_arr, 0, size);
SG_EXTRA_DEVS is defined in hosts.h:
[hosts.h] 507: #define SD_EXTRA_DEVS CONFIG_SD_EXTRA_DEVS 508: #define ST_EXTRA_DEVS CONFIG_ST_EXTRA_DEVS 509: #define SR_EXTRA_DEVS CONFIG_SR_EXTRA_DEVS 510: #define SG_EXTRA_DEVS (SD_EXTRA_DEVS + SR_EXTRA_DEVS + ST_EXTRA_DEVS)
Now, the define CONFIG_SD_EXTRA_DEVS depends on whether or not I want to include SCSI disk support... If i don't define CONFIG_BLK_DEV_SD, then I don't get the option of choosing how many extra disk devices I want, and CONFIG_SD_EXTRA_DEVS doesn't get defined in my .config...
I'm not sure exactly what the fix is... I was trying to compile scsi emulation for my cdr drive, and I usually never compile in scsi disk support... Is it required to do this now?
It is ok to define CONFIG_SD_EXTRA_DEVS when I don't have disk support compiled in? I'm not sure what the right fix is for this... the scsi code may need to be modified, or the Config.in script may need to be modified...
Please CC me, as I am not on the list.
Anyway, thanks in advance for your time.
