 Posted: Tue Nov 16, 2004 3:02 pm Post subject: Building a Redhat 9 kernel on Gentoo |
 |
|
OK, Here's the short. I am trying to set up a Gentoo box to fool Rational Clearcase into thinking it's a Redhat 9 machine. Hacking the install script isn't hard - but linking the MVFS module (for dynamic code views, which isn't a requirement for Clearcase to work but is a very nice feature) is damn near impossible on a 2.6 kernel.
So what I did was I tarred up /usr/src/linux-2.4.20-8 directory on a Redhat 9 box, and instead of emerging a kernel sources ebuild during the installation process, I untarred the Redhat 9 kernel source.
At first I tried using
genkernel all --menuconfig
and when that didn't work, I reverted to manual configuration, which also didn't work. It seems to be having problems with the aic7xxx driver which I need for scsi.

Any ideas? Is a gentoo kernel sources ebuild more than just the kernel sources (and patches)?
TIA... |

OK, I worked around that one by setting aic7xxx to compile as a module.
It now seems to be choking on something (correct me if I am wrong) that I can't compile as a module. devfs is required to be compiled statically, correct?

Did you ever get Clearcase working? I just started on a new project that uses clearcase and I have had nothing but trouble getting the kernel modules to compile. So I am now going down this road as well, but I don't really want a separate kernel for clearcase work than from my everyday use.
Currently when I try to compile the kernel module, I get the following:

A google on ATRR_FROM_OPEN doesn't reveal very much.
I did get the module to comple once, but I modified much of the source to use the 2.4 code instead of the 2.6 changes. The module loaded, but there was a kernel OOPs when I started the clearcase processes. Clearcase then claimed that the modules were not loaded, and I couldn't rmmod them because they were "busy". |
