[gentoo-ppc-user] What should I copy from Ubuntu
Hi, Sorry for a semi-cross post between the yaboot list and Gentoo-ppc-users. I'm hoping to get this worked out today. I had trouble a week ago getting a new Gentoo PPC install to boot on my Mac Mini so for kicks I tried Ubuntu which booted fine. I'd like to get back to running Gentoo and I'm wondering what information I should retain from my Ubuntu installation. The new Gentoo install is back on the Mac Mini and completely up to date, so if I can work out the booting issue I should be good to go. I have not emerge yaboot as of yet as I don't want to break Ubuntu until the last moment if possible. To boot do I need anything beyond the info contained in the Ubuntu yaboot.conf, the hard drive partitioning and fstab to get Gentoo working? That's should be enough to somehow construct things correctly in Gentoo, correct? Also, the Ubuntu install used an initrd. I presume this is because their one-size-fits-all approach probably requires drivers to boot a lot of different machines. Previously when I had this Mac Mini running Gentoo I didn't use one. I don't need to, correct? (Assuming I can find and build in the right drivers?) Is there anything about yaboot vs grub that makes it prefer an initrd? For now I used the Ubuntu .config for my Gentoo kernel and figured I'd trim it down later after I get the machine at least booting.

Re: [gentoo-user] sudo in kernel config ?
In linux.gentoo.user, you wrote: Some people, such as myself, use kernel sources outside of portage (I follow a git repo) and do so as a non-root user. In this case the kernel tree is not owned by root and the config/compile is easily done as a non-root user. If you are super-paranoid. You can make a non-root copy of /usr/src/linux and compile it as a non-root user. But there really isn't any point in using sudo. It's effectively doing the same thing that you are trying to avoid. I agree there's no point in using sudo, but what's the problem? You don't need to edit the kernel sources merely to build a new kernel. You can build your kernel outside the tree using for example: make O=/home/user/kernel/tree/ menuconfig make O=/home/user/kernel/tree/ All files are put into the user's directory. All that's need is the KBUILD_OUTPUT environment variable set, so that drivers can find the kernel .config file etc. I've built my kernels like this for years now. All kernels are built by a specific user and then installed as root. No problem, no worries about permissions and no altering the portage installed kernel sources so that a purge (emerge -P gentoo-sources) will automatically remove the whole tree. -- Regards, Gregory.
Re: [gentoo-user] Re: static-libs
DL libraries aren't really a different kind of library format (both static and shared libraries can be used as DL libraries); Library archives (.a) and shared objects (.so) differ in several ways. Roughly speaking: From a file format perspective, .a files are simple collections (man ar) of independent compiled objects, while .so files are complete libraries produced by the linker and contain additional information which tell the dynamic linker (ld.so) how to load and share the code. More importantly, code which is intended to be used in shared objects must be compiled with specific options as position-independent code, whereas code in an archive needs not. You can't link dynamically against a library archive, so all DL code on Linux must be compiled as a shared object, whether it's actually shared or not (think plugins). As for the static use-flag: don't use it, unless you have very good reasons to do so. It will result in a system with larger binaries and in many cases you will *not* get true statically-linked binaries (e.g. most of the things which link against glibc). As for dynamic linking breakage following upgrades, IMO portage and revdep-rebuild give good enough support for fixing that. andrea

Enabling this flag will install a static version of libjpeg alongside the dynamic one. You do not need to worry; other programs will continue using the dynamic version, since this is the default. The static version will only be used by programs that specifically demand it and would otherwise not work. So there are no consequences at all in enabling this USE flag.

I have jpeg-8b, so I can't be sure about 6b. I just turned on the static-libs USE flag and re-installed jpeg. The only difference is that the 'static' lib /usr/lib/libjpeg.a wasn't there before and it is now, that's all. Is your system trying to upgrade jpeg to a newer version? I notice that 6b doesn't use any USE flags, and the newer versions do use the static-libs flag. (Just re-installing 6b shouldn't complain about USE flags because the package doesn't look for them.) Any program that uses the dynamic libjpeg.so would need to be re-compiled if the version of jpeg changes. If the static library is used instead, the program no longer needs libjpeg.so because the static library is linked into the binary executable at compile-time. The price you pay is a larger binary executable, but you never need to worry about future jpeg version changes. I don't know how portage chooses between static and dynamic libs while building a package. Anyone else know? In fact, static-libs is for jpeg-8b , but Imade a mistake when write the mail...

I agree there's no point in using sudo, but what's the problem? You don't need to edit the kernel sources merely to build a new kernel. You can build your kernel outside the tree using for example: make O=/home/user/kernel/tree/ menuconfig make O=/home/user/kernel/tree/ This is how I do it, too, when testing the kernel before I do it for real. This way, the code stays owned by root and I can make to my hearts content, with different kernels going into different directories that I control. -- Bill Longman

Re: [gentoo-user] Re: static-libs
So why shouldn't you be able to load an unshared lib (without PIC) dynamically? Sure there still would be some additional steps. I am not talking specifically about PIC/non-PIC code here. PIC is relevant because when you're doing dynamic loading you generally cannot predict at what (virtual) address in the process space the loaded object will end up at. That said, whether you can dynamically load non-PIC code depends on the specific architecture (e.g. on x86 you can have non-PIC code in shared objects, albeit at the price of the dynamic linker having to patch all relocations in the loaded object, while on amd64 you can't because the ABI allows certain kinds of relocations in non-PIC code which cannot be handled this way.). What I am saying is that there is no way to dynamically load code from a .a file, at least not with the system tools, period. There are reasons for this: first, a .a is not a real library but a collection of independent compiled objects (building a .a does not entail any kind of linking: it's about the same as tar'ing .o files together). Moreover, the dynamic linker (ld.so) needs a certain amount of information about the contents of any object it has to load: this information is stored in specific ELF sections and is computed and written by the standard linker (ld) when it builds the shared object from its components. andrea

You might want to consider USE flags before you do that, but I don't think it will cause any problems other than possibly something not compiling. Remember that stable on 64-bit doesn't necessarily exactly equal stable on 32-bit so you might be getting different revisions, etc. Hope this helps, Mark

[gentoo-user] emerge - pointing to local file

Not necessarily. But it can't be shared at runtime anymore, since the dynamic loader has to change the codepages for each process. (well, there *is* a way ... back in a.out times libraries hat been compiled/linked to specific address spaces, but obviously that's quite complex to manage and not advisable outside speficic embedded environments) You can't link dynamically against a library archive, so all DL code on Linux must be compiled as a shared object, whether it's actually shared or not (think plugins). You can (apache did it once, aeons ago), but it's quite tricky, and it's hard to get the pages shared between processes.

You put the tarball in /usr/portage/distfiles. I think he's asking about the ebuild. The version he wants is not in portage. Joseph, If you have the package *already* installed and want to remerge it, there's a local copy of the ebuild in /var/db/pkg/cat/pkg-version copy it from there to your local overlay and remerge as normal. If you unmerged the package already, then the ebuild is gone. Maybe you have a backup. There's also an svn attic somewhere where everything that was ever in portage is stored.
