Re: Error trying to compile Comedi under RedHat

Anyway, to answer my own question.
Redhat screwed up the update of the remap_page_range() function.
It was supposed to change from having 4 arguments to 5 after ver 2.5.
But Redhat reverse ported the mods to revision 2.4.20.

The fix is to go into (comedidir)/include/linux/mm.h and change line
#if LINUX_VERSION_CODE < KERNEL_VERSION(2,5,0)
to 
#if LINUX_VERSION_CODE < KERNEL_VERSION(2,4,20)

Also, when changing the Makefile Extraversion setting on a multiprocessor system,
make sure the smp suffix is there to match the uname -r suffix
i.e.
EXTRAVERSIOIN = -28.7smp


over and out.

  Subject: Error trying to compile Comedi under RedHat


  Hi,
  I'm trying to install Comedi on my RedHat System and I get compile
  errors during the make. Here is the tail end of the build report.

  Anyone have any idea what I might be doing wrong?

  Thanks,
