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

Please be gentle with explaining this sorte of things, as I have not the knowledges to understand the full compile process, otherwise I am a little bit familiar with it ! 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.

Of course, but it may affect different people to different degrees, or may not even affect some of them. That's what I meant.

[gentoo-user] dhcpd missing in stage3 of AMD64...?
Hi, currently I am on the way to install a AMD64 root system. I use the AMD64 gentoo iso to boot into a 64bit system. There was a net-connection without any problems (using DSL and dhcp). After several steps I chrooted into the new environment and ... no net anymore. eth0 was up (ifconfig) but dns does not work. No wonder...there was no dhcpd (at least in /sbin/. ) in the stage3 tarball (I extracted portage too...). So...how can I go further... Best regards, mcc

That's always worked for me. I don't think you require dhcpd to make this work. All you have to do is point at your DSL router, assuming the router has dhcp enabled. The router serves up the IP addresses and also acts as the name server. I think possibly you missed a command. - Mark

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.

[gentoo-user] emerge - pointing to local file
Can someone refresh my memory how to emerge application pointing to local source file? I need to re-emerge: asterisk-addons-1.4.7 but it does not seems to exist on any mirror (I have in may make.conf), I found asterisk-addons-1.4.7.tar.gz file but I need to point emerge to local file instead. -- Joseph

[gentoo-user] automatically updated certain packages
Hi folks, I've got a tricky task for automatic update script, which requires some portage magic ... The script has a list of packages which should be updated completely automatically, but *only* if they're pulled in as dependency (beginning from world), and others not in that list should *not* be updated. Is there any easy way to do it ? cu -- -- Enrico Weigelt, metux IT service -- http://www.metux.de/ phone: +49 36207 519931 email: weig...@metux.de mobile: +49 151 27565287 icq: 210169427 skype: nekrad666 -- Embedded-Linux / Portierung / Opensource-QM / Verteilte Systeme --

All I'm proposing right now is adopt the model, which makes collaboration w/ other distros easier. It's something like an aggreement as FHS.

Not necessarily. But it can't be shared at runtime anymore, since the dynamic loader has to change the codepages for each process.

You can (apache did it once, aeons ago), but it's quite tricky, and it's hard to get the pages shared between processes.

So I think they are related. If your patch import system works, it can become very interesting. You can run something similar to Gentoo without the need of a big community at the beginning. So you have all freedom to customize it just the way you want it. Al

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//- 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. I don;t know where it is, but Google does. Search for it. -- alan dot mckinnon at gmail dot com

However if you are running emerge app1 app2 app3 then the man page implies it won't do what you want. I don't know when this feature arrived.

So I think they are > related. I've designed the two projects so that they're independent from each other, but just play very well with together. OSS-QM repositories [1] are layed out in a way that it's trivial to fetch specific version of the packages, and also allows separate namespaces (prefixes) for individual distros (so they can push their work directly to oss-qm w/o stepping onto other's feet). > If your patch import system works, it can become very interesting. Well, for Debian it already works quite well, Gentoo still is unsolved, as I'm lacking information to construct the history. (a little help from Gentoo devs would really be appreciated). > You can run something similar to Gentoo without the need > of a big community at the beginning. So you have all freedom to > customize it just the way you want it. Actually, I already *do* have something similar - by combination of OSS-QM and Briegel.

[gentoo-user] what's going on with updates ?
Since few days ( two or three ?), every time I launch emerge, it's saying me it needs an update of portage itself. In plus, I have upgraded udev at least two times (160>161>162 today)... Plus, I have had two warning message concerning updates : sudo and an other... what's going on ?
