Hi,
I have a few questions about compiling a new kernel. I keep getting the
following error.
kern_sysctl.o: Undefined symbol '_hw_float' refrenced from text segment
Why?
I did a few tests. I compiled a GENERIC kernel and it compiled just
fine. It is only after I modify the config file that I copied per the
instruction 6.0.2 that I get this error.
I copied over the file and made no changes and it compiled without
errors as well.
Now, I have no SCSI devices, or Ethernet devices connected to this
computer. Included in this file I have sent is the output of dmesg. As
you can see I am not using many of those things that come in the GENERIC
kernel at all. What I am trying to accomplish is a smaller kernel
without the "dead" code that never gets used. I would also like to take
advantage of my 387.
Please keep in mind that it has been taking about 3.5 hours to compile a
kernel. This may be usefull for troubleshooting.
Thanks for reading....
