Hi, there,
I began to work on embedded linux applications with
Red Hat Linux 7.3 and kernel-2.4.18 Release.
The following problems were encountered when trying to
rebuild new kernels:
1. Is it normal for long time to finish?
It took over 3 hours to complete successfully using command:
rpm -bc kernel-2.4.spec
where Source packages from installation of Red Hat CDROM disks,
PC hardware: Pentium II 450M Hz, RAM 128M, Filesystem ext2
no changes for config and specs
2. How to change config?
I commented out some un-necessary items from
/usr/src/redhat/SPURCES/kernel-2.4.18-i686.config
then issues "rpm -bc kernel-2.4.spec"
after about 1 hour, many prompts came out, like
ATIXL busmouse support (CONFIG_ATIXL_BUSMOUSE) [N/m/?]
Logitech busmouse support (CONFIG_LOGIBUSMOUSE) [N/m/?]
Microsoft busmouse support (CONFIG_MS_BUSMOUSE) [N/m/?]
MK712 touch screen support (CONFIG_MK712_MOUSE) [N/y/m/?]
Acquire SBC Watchdog Timer (CONFIG_ACQUIRE_WDT) [N/y/m/?]
Advantech SBC Watchdog Timer (CONFIG_ADVANTECH_WDT) [N/y/m/?]
ALi M7101 PMU Watchdog Timer (CONFIG_ALIM7101_WDT) [N/y/m/?]
AMD "Elan" SC520 Watchdog Timer (CONFIG_SC520_WDT) [N/y/m/?]
......`
zlib compression support (CONFIG_ZLIB_DEFLATE) [N/y/m/?]
Finally, rebuilding failed with the message:
make: *** [oldconfig_nonint] Error 1
error: Bad exit status from /var/tmp/rpm-tmp.86315 (%build)
RPM build errors:
Bad exit status from /var/tmp/rpm-tmp.86315 (%build)
I noticed that there are 3 sets of config for Intel arch in
/usr/src/redhat/SOURCES:
kernel-2.4.18-i386-BOOT.config
kernel-2.4.18-i386.config
kernel-2.4.18-i386-smp.config
kernel-2.4.18-i586.config
kernel-2.4.18-i586-smp.config
kernel-2.4.18-i686-bigmem.config
kernel-2.4.18-i686.config
kernel-2.4.18-i686-debug.config
kernel-2.4.18-i686-smp.config
kernel-2.4.18-i686-uml.config
In order to remove some un-necessary device drivers from kernel and
loadable modules, what config files above shall be updated?
How to keep them consistent?
3. MIPS patch problem:
I tried to build target kernel for MIPS without any changes
of config and specs using command:
rpm -bc --target MIPS kernel-2.4.spec
After about 10 minutes, rebuilding failed due to
patch problem, like:
+ echo 'Patch #280 (linux-2.4.16-mips-20011220.patch):'
Patch #280 (linux-2.4.16-mips-20011220.patch):
+ patch -p1 -s
Reversed (or previously applied) patch detected! Assume -R? [n] y
1 out of 8 hunks FAILED -- saving rejects to file arch/mips/Makefile.rej
Reversed (or previously applied) patch detected! Assume -R? [n]
out of 8 hunks FAILED -- saving rejects to file arch/mips/Makefile.rej
......
The similar situation happened for ARM arch as well.
I'm wondering if this source package works with MIPS and ARM.
If not, where can I get a working version for MIPS and ARM rebuilding?
Thank you!
