Ken, I don't know how to check against the 32 v 64 bit. uname reports: Linux hojo-lfs-6.8 2.6.38.2-LFS6.8 #1 SMP Mon Apr 18 20:35:16 MDT 2011 x86_64 x86_64 x86_64 GNU/Linux I have picked out a shell script that runs very slowly from the configure script from openssh.

If I run this in a loop on the LFS box top shows the following while bash only consumes around 7 to 9% of the cpu and a scant of memory. Cpu(s): 0.0%us, 25.7%sy, 0.2%ni, 74.0%id, 0.0%wa, 0.0%hi, 0.2%si, 0.0%st I'm not sure why you want multiple CPUs in a virtual environment when you can clone a new one for each task. I'm not sure how to do that.

Kernel options help
To list, I built a new LFS 6.8 and everything is kosher save for some slowness. I built an x86_64 kernel (2.6.38.2) all on a Xen host (5.6.100) on a Quad Proc Xeon. It boots with no issues until I try to configure a package. As an example, if I run the ./configure for the openssh package, it takes around 5 min just to configure. Making with -j4 tends to go well but still not as fast as I think it could. It shouldn't be a Xen issue as my LFS build system was the LFS live CD. Configuring under the liveCD proceeded at a normal rate. I've tried a few different kernel options but none seem to make any difference. Any help would be appreciated. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
UDEV and 2.6.38 kernel headers
I seem to have encountered this issue ( http://comments.gmane.org/gmane.linux.lfs.devel/10624 ) just now though it seems the patch isn't in the patch list nor in the instructions. Did I miss a step? I manually applied the patch and had to copy two headers from the kernel headers in order to get it to fly. http://comments.gmane.org/gmane.linux.lfs.devel/10624 Headers I was missing were /usr/include/linux/videodev2.h which calls /usr/include/linux/compiler.h -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

The 2.6.38 kernel no longer installs the file videodev.h but that's a different file, you say you were missing videodev2.h which is not affected by the patch. Yeah, I even re-ran the 6.7. Linux-2.6.37 API Headers section (with 2.6.38.2) and it was a no go on videodev2.h. It was in the kernel tree but never made it out to /usr/include/linux. Output from make INSTALL_HDR_PATH=dest headers_install indicates INSTALL include/linux (360 files). And there seem to be just that many. I have a snapshot of my build chain so I can go back and give it a shot from the ground up and see if it repeats.

jhalfs build report
I ran a jhalfs build last night and was wondering if anyone want's the report. I seem to recall that a while back the developers wanted these reports.

Re: Building a LFS system

I just want to get the files needed to for the lfs box and be able to just install the file on the box and compile the other files needed so I don't need to deal with bloat and install only what I want on my box. LFS, if you already haven't figured, is designed to be built on a host. That host does not have to be installed. See below... I just want to build my own linux box. Why don't you start with a live CD, boot from the CD and use that to compile LFS? You need to have a precompiled gcc, glibc, etc to start with but you don't have to install them onto your hard drive if you use a live CD. I've built LFS (aLFS) from the Live CD and it works rather well.
