Re: [blfs-support] LLVM lib path
On 01/06/2013 08:51 AM, Simon Geard wrote: A curious question, for anyone who might know. Why, in the LLVM instructions, do we go to such lengths to put all the libraries in a subdirectory of /usr/lib, only to add an entry to ld.so.conf to ensure everything can find them? I ask because I missed that last bit without noticing at the time, only to have some other package try and run clang and fail with library loading issues. And neither the book, nor the patch offers any explanation of why we want to fix installation paths for libraries. Note - I'm aware that the patch also fixes the locations of stuff in /etc and /usr/share/doc, no problem there. It's just the reasons for forcing everything into /usr/lib/llvm that has me puzzled. Simon. Well, I guess answer is simple. We didn't want to polute /usr/lib with ~100 static libraries which are only used by programs that use LLVM. Entry to ld.so.conf is added because there are few shared libraries, ensuring that they can be loaded at runtime. Some time ago, LLVM was installed into /opt/llvm by default because of mentioned reason, but we agreed to install it into /usr hierarchy - just changed the libdir. -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page

I wasn't intending show you my code to modify this after it has been
copied in, because it is really ugly, but in the end it's easier to
show it as one way which works to copy and alter the relevant lines.
The debugging info is there in case it fails - only ever tested with
4 CPUs.
# if more than 1 cpu, replicate for all of them - print debug info while it
checks
echo -n searching to see if more than one cpu...
let EXTRACPUS=`cat /proc/cpuinfo | grep MHz | wc | awk '{ print --$1 }'`

My old ppc64 was much more involved - had to load powernowd to be
able to control the frequency.
I'll also note that you can specify a default governor in the
kernel.
ĸen
In the kernel source code there is a app called cpupower that one just
needs to build. It can then be used as a user not root to set what
ever governor that you want. This could be included on the kernel build
page or made standalone. the cpupower app just requires cpupower
frequency-set -g governor and it sets for all cpu cores, you can also
change on the fly. One just needs the governor modules loaded or built
into the kernel for this to work.

The main thing is that there is no good reason to use a different version of systemd/udev in BLFS than what you used in LFS. And use the latest lfs tarball for that version. Correct. But, without trying it, I think udev can be updated in place. You just need to follow the LFS instructions for the base install and the BLFS instructions for keymap, gudev, and gogject files. The important part is not to mix versions. There is text in BLFS: --- Udev-Installed LFS Version: If you installed LFS from SVN-20120719, LFS-7.2, or later, use udev-extras (from systemd) instead of this page. Unlike any other package in the BLFS book, there is no set version of Udev specified to download. Several version updates to LFS and none to BLFS means there are probably many different versions of Udev on the platforms that BLFS is being built upon. Therefore, you should download and use the version of Udev your computer currently uses. Udev Extras (from systemd): ...you should download and use the version of systemd your computer currently uses. Udev Extras Dependencies Required http://anduin.linuxfromscratch.org/sources/other/ (match the udev-lfs-???.tar.bz2 tarball version to the systemd version used in LFS).

[blfs-support] iptables
I couldn't access the archives, so I thought I would go ahead and ask. Why did the iptables bindir get changed from /sbin to /usr/bin? It sure seemed to add quite a bit to the install step. Also, I didn't need the LDFLAGS doing an upgrade. I suspect that was just because the libraries already existed. Although I did need to use a sed before doing 'make install'. sed -i 's/-dm0755/-d -m0755/' iptables/Makefile Looks like just a typo in the file.
