Re: [gentoo-user] Installing an old glibc to run a proprietary commercial tool (would that even help?)
2009/10/30 Volker Armin Hemmann volkerar...@googlemail.com: Virtualbox on the other hand is pretty much hassle free in my experience. Can't talk about vmware - haven't used that in years ;) Thanks for the pointer to Virtualbox... I hadn't heard of it. Looks like the wiki has some help, though. http://en.gentoo-wiki.com/wiki/VirtualBox I'll give it a shot before vmware.

2009/10/31 William Kenworthy bi...@iinet.net.au: I was in a similar position some years ago - grab a copy of the needed libs from somewhere and use ldpreload to load them into memory before running the application. Google will help. In some cases, you can symlink the needed lib names to existing later libs and run ldconfig before trying to run the app. This does work sometimes, but success varies ... BillK Interesting... I may give that a shot. Should be able to crank out a wrapper script to do that automatically. It'd be prudent to have RHEL4 anyway, since that's what some of our customers are running, but it's good to have another option.

I suspect the problem is that RHEL v4 uses =sys-libs/glibc-2.3.4, whereas we have =sys-libs/glibc-2.9_p20081201-r2 installed. I have three questions: 1. Am I posting to the right list? You are just just as likely to get support from Gentoo about software we have no access to as your distributer is to support Gentoo. 2. Any idea what's going on? Could it be something other than glibc causing the problem? It could be one of a hundred million things. Without access to the program it's really hard to tell. 3. If it is glibc, is there some way to install glibc slotted? Could I install an old version of glibc to some other lib folder (like /opt/lib64), and then use LD_LIBRARY_PATH somehow to get the tool to look there first? How? You can't have multiple versions of glibc. And you can't downgrade glibc. Attempting to do so may result in having more than just that program misbehaving ;) My suggestion, for your sanity and support: if you insist on Gentoo then at least run RHEL4 (or CentOS or whatever) inside a virtual machine and run your app from there.

Re: [gentoo-user] Installing an old glibc to run a proprietary commercial tool (would that even help?)
Thank you both for your quick response. I'll probably end up taking the virtual machine approach. I may also try some sort of chroot solution... I'll see how much of a hassle vmware is. 2009/10/30 Volker Armin Hemmann volkerar...@googlemail.com: On Freitag 30 Oktober 2009, Albert Hopkins wrote: 3.

I'll see how much of a hassle vmware is. chroot can work nicely, but you have to create a gentoo with a very old glibc. The problems might not be worth it. Virtualbox on the other hand is pretty much hassle free in my experience. Can't talk about vmware - haven't used that in years ;)
Re: [gentoo-user] Installing an old glibc to run a proprietary commercial tool (would that even help?)
Avoiding 1, 2, and 3 but thought I'd propose a 4 other than a virtual machine. Ask the vendor if they can provide a statically compiled version, that way you don't have to worry about libc. I dunno how flexible the vendor is but its worth asking :) On 10/30/09, Duncan Smith duncanphilipnor...@gmail.com wrote: The company I work for is using gentoo on all its machines.
