I noticed one person mentioning 64bit LFS on a previous post. It made me wonder how LFS may address this in the future.
On my own, I took the multilib plunge about 6 months ago. (sortof a hodgepodge of LFS's buildsystem, and a few occassional CLFS patch's). I had the following ideals in mind in the construction of my own system. (I dont know how close these are to LFS values) -I wanted a pure 64bit os, or at least a system where 32bit could be added on later. (To this end, I built a multilib gcc/glibc/binutils, but no other 32bit libraries unless I specifically had a program link against them) -I dont like the idea that if I was to install a 32bit version of a package, that it would overwrite the 64bit binaries. (goes against my first idea, where I wanted 32bit as a addon). [although this one has caused a few headaches]. I know one can install the 64bit version after, but it just feels wrong. -I like the concept of building the simplest system first, and giving options later in BLFS. (such as the 32bit environment). -I prefer to use standards (if appliable) to find the location of 32/64bit libraries. CC=gcc -m32 is smart enough to find /usr/lib, while gcc can see /usr/lib64. I also found that overriding PKG_CONFIG_PATH to /usr/lib/pkgconfig or /usr/lib64/pkgconfig is a great way of helping a config script find it's dependencies. -CLFS/BCLFS has done alot of work to make 32/64bit buildsystems work relatively seemless, but I do not like the concept of the multiarch_wrapper they made. (Saying that, I dont know of a better solution). Most packages seem to use pkg-config either in conjuction, or instead of programs in /usr/bin that tell you where to link against. That is not the case for all programs though. note: more details on the multiarch wrapper can be found at http://cross-lfs.org/view/svn/x86_64/final-system/multiarch_wrapper.html. -- Nathan Coulson (conathan) ------ Location: Alberta, Canada Timezone: MST (-7) Webpage: http://www.nathancoulson.com -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
