Post subject: [gentoo-user] Installing an old glibc to run a proprietary commercial tool (would that even help?)
Archived from groups: linux>gentoo>user (more info?)
|
|
|
The company I work for is using gentoo on all its machines. We just
got a license to a commercial tool which does not support gentoo. The
closest thing it supports is RHEL v4.
Running any command provided by the tool results in an explosive
memory leak (virtual memory hits 400G in 1 second, and continues to
climb).
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?
2. Any idea what's going on? Could it be something other than glibc
causing the problem?
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?
Thanks for any help or ideas.
Duncan
P.S. In case it's useful, here is the output of ldd:
linux-vdso.so.1 => (0x00007fff9e3ff000)
libncurses.so.5 => /lib/libncurses.so.5 (0x00007f49c871b000)

libdl.so.2 => /lib/libdl.so.2 (0x00007f49c807a000)

you can have multiple glibc's. Just not via portage.
But yes, it is a mess. A mess that is most likely to explode violently.

yeah, I would go down that route too. |

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.

It could be one of a hundred million things. Without access to the
program it's really hard to tell.

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. |

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.

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 |

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

If it's a somewhat critical machine for business, just drop a new stand-alone
box running RHEL4. Critical machines usually generate|save more cash than the
cost of the box they run on

They only support RHEL4. RHEL4 was released nearly 5 years ago and uses
the 2.6.9 kernel. I think that shows how flexible they are. |

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 ...

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. |

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. |
