Description todd underwood 2001-10-18 17:28:00 UTC

Description of Problem:

gcc stops when trying to compile scsi_ioctl.c in kernel's 2.4.7 2.4.11 2.4.12.

Version-Release number of selected component (if applicable):
gcc -v
Reading specs from /usr/lib/gcc-lib/ia64-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-81)

How Reproducible:  completely

Steps to Reproduce:
1.  download one of the kernels above
2. patch with appropriate patches from kernel.org/pub/linux/kernel/ports/ia64
3.  make menuconfig and select some scsi options (we have scsi disk, scsi generic 
and the SCSI_QLOGIC_1280 drivers (either as module or as built-in).
4.  compile

Actual Results:
make -C scsi modules
make[2]: Entering directory

Please submit a full bug report.

make[2]: *** [scsi_ioctl.o] Error 1


Expected Results:

compilation should work.

Additional Information:

Comment 1 Jakub Jelinek 2001-10-18 17:40:33 UTC

Please try gcc-2.96-98 or 2.96-99, it should be fixed there.

Comment 2 todd underwood 2001-10-19 15:06:27 UTC

2.96-99 does, indeed work.  thanks.
