 |
|
while trying make image modules_install with the 2.6.7 kernel i am getting a lot of warnings saying "needs unknown symbol _mcount"
make went through without any errors
Any ideas?
INSTALL drivers/scsi/sg.ko
INSTALL arch/sparc64/solaris/solaris.ko
if [ -r System.map ]; then /sbin/depmod -ae -F System.map 2.6.7-gentoo-r14; fi

Have no sparc but I guess you have not configured this option into your kernel config
| Code: | | zgrep MCOUNT /proc/config.gz |

thx for your input.
zgrep MCOUNT /proc/config.gz, zgrep mcount /proc/config.gz, zgrep MCOUNT /usr/src/linux/.config couln't find anything.
i have marked every feature within in the kernelconfiguration to compile into the kernel... the error has gone. But thats not really a solution....
now make image modules_install complains about the missing serial.h. this file was really missing, don't know why. copied it from my x86 system over and it worked. i have fetched this sources via emerge!?!?! |

Seems that this option is not stored in the config file if not selected.

Kernel config options are always upper case! But you can use the grep option -i to ignore the case! (grep -i ab: finds ab, Ab, aB, AB)
| Quote: | | zgrep MCOUNT /usr/src/linux/.config |
The file you greped is NOT compressed! So it is not possible to find anything. You have to use grep MCOUNT ... for normal text files.
zgrep <> is only a shorter version of gzip -d -c /proc/config.gz | grep <>
I'm not able to see the MCOUNT option in my menuconfig but I looked through the Kconfig file in source.
| arch/sparc64/Kconfig wrote: | | Code: | ...
menu "Kernel hacking"
...
config MCOUNT
bool
depends on STACK_DEBUG
default y
... |

Hope you now know where to search for this option in menuconfig!

That's no good solution at all! 
Try to select only the things you want to have in your kernel and may be some as modules! Don't forget the mcount option under kernel hacking.
| Code: | $ find /usr/src/linux/include -name "serial.h"
include/linux/serial.h
...
include/asm-x86_64/serial.h
...
...
... |
In my kernel source tree there is no 'serial.h' for sparc(64)!!
Can you please post the error messages when compiling the kernel. |

| Unless you've thrown in an additional serial controler, you can disable 8250 support. Depending on your model of sparc, you'll either want sunzilog, sunsab or sunsu support. |
