Hello, On April 7th I tried to build system by using Gentoo 1.4 RC3 for x86. To do so, I started from Stage 1 and I specified in the menu.conf machine that I was willing to build a system for an i686 with the -O2 optimisation. Using the latest portages, gcc 3.2.2 and glibc 2.3.1-r2 (I think...) have been built as well as the rest of the stage 2 and stage 3 packages without any single problem. Then came the kernel building. I tried to compile the openmosix kernel with the kernel .config files from: - RedHat 8 and 9 beta with the modifications required by Gentoo Linux (Reiserfs, /proc, ext3, ext2, virtual memory...) and the openmosix features. - Openmosix directly (.config file taken from their rpm source file) with the modifications required by Gentoo Linux (Reiserfs, /proc, ext3, ext2, virtual memory...) None of these kernels built correctly. I always ended up with one module or the other generating a compilation error. I suspect that this is due to the use of gcc 3.2.2 on vanilla sources. So here is my requirements: Couldn't it be possible to add a new entry to the sys-kernel directory? a gentoo-openmosix-sources with: the patches to be applied to the vanilla kernel to have it built on Gentoo (gcc 3.2.2) + the openmosix code. Reproducible: Always Steps to Reproduce: 1. Build stage 1, 2 and 3 with Pentium 2 -O3 (Gentoo 1.4 RC3, date of built 05/04/2003) 2. Choose the openmosix-source kernel, use the RedHat 9 beta .config file with the correction for Gentoo Linux (Reiserfs, /proc, ext3, ext2, virtual memory...) and the openmosix features or the openmosix .config file (taken from their rpm source file available on openmosix web site) with the modifications required by Gentoo Linux (Reiserfs, /proc, ext3, ext2, virtual memory...) 3. Compile the kernel according to the method described in the Gentoo Linux installation procedure Actual Results: Many modules do not built (it depends on the selection made). I suspect gcc 3.2.2 is responsible. Expected Results: A modular kernel with the openmosix functionalities. Well, as I said, I think it could be useful and wise to create a new entry, a gentoo-openmosix-source containing patches for the kernel + the openmosix source code.
Ok, as i can compile the newest version of the official gentoo-openmosix kernel ( sys-kernel/openmosix-sources Latest version available: 2.4.20-r3) without no problems on my gcc-3.2.2 and glibc-2.3.1-r4 system I'd ask you to include some more information: - Output from "emerge info" - Version of the sources you tried to compile - Attach the .config file you used <quote> So here is my requirements: Couldn't it be possible to add a new entry to the sys-kernel directory? a gentoo-openmosix-sources with: the patches to be applied to the vanilla kernel to have it built on Gentoo (gcc 3.2.2) + the openmosix code. </quote> I don't know what you mean with this. We have openmosix-sources in the sys-kernel directory.
Well, I do not have my Gentoo Linux box here at the moment. Besides, since then I tried to reinstall it using the gentoo-source kernel instead (without success either, I have exactly the same kind of problems, some modules do not build (see bug report 18969)). I did my experiments on april 7th. By that time I think it was openmosix 2.4.20-r2, but this remain to be checked and confirmed (that should be easy with the dates of the .ebuild files). About my .config file. I had several and none of them worked.... I join one that should demonstrate the problem. It is based on the RedHat 2.4.20 kernel. I added the gentoo-linux options and by loading it with the kernel option configurator (menuconfig I think is the name of the program), the basic openmosix flags should be automatically added. Now try to compile it (By then I used the defaults options for the architecture and the optimization (i686, -O2)) and see if it works. What was I refering too in my bug report? I was wondering if the openmosix kernel was: - A vanilla kernel + openmosix add-on - A vanilla kernel + pactches + openmosix add-on Considering the problems I had, I came to the conclusion that I was dealing with the first option and I was simply proposing to add the second one. One named for instance : gentoo-openmosix-source or whatever.
Created attachment 10670 [details] As requested, my .config file Here is a typical .config file I am using. It is modular and I like this feature. I am neither skilled enough nor intressed enough to create by myself a .config file. I borrowed the .config file of the redhat kernels (I like its modular nature) and I tried to adapt it to gentoo linux (according to what is written on the installation manual). Unfortunately, it seems that some of the modules chosen do not compile correctly. The .config file simply triggers compilation problems (openmosix and gentoo-source as well).
Problems look like general problems from the openmosix-patchset which is known to not compile is some kernel options are enabled.
Closing this bug.
