When trying to start an app called fieldview (http://www.ilight.com) I get: relocation error: ./fvbin: symbol errno, version GLIBC_2.0 not defined in file libc.so.6 with link time reference With glibc-2.3.4.20041102-r1 this problem could be resolved by using LD_ASSUME_KERNEL="2.4.8" prior to starting fv. After upgrading to glibc-2.3.5-r1 LD_ASSUME_KERNEL does nothing to alleviate the problem. Downgrading to glibc-2.3.4.20041102-r1 helps. Reproducible: Always Steps to Reproduce: 1.export LD_ASSUME_KERNEL=2.4.8 2./opt/fv10/bin/fv Actual Results: fieldview exits with: relocation error: ./fvbin: symbol errno, version GLIBC_2.0 not defined in file libc.so.6 with link time reference Expected Results: fieldview should start I realize I should probably pester ilight about this instead, but as I thought this might be applyable to more software than fieldview (f.ex. matlab) a bug might be in order anyway. The problem occured on a production server with a bunch of users breathing down my neck, thus I didn't have the time or peace of mind to do more thorough checking. I googled around as much as I could for more ways to diagnose what specifically had gone awry, to no avail. Oh, BTW, this is my first bug, please go easy on me ;-) - Linus Harling
re-emerge glibc with USE=glibc-compat20
(In reply to comment #1) > re-emerge glibc with USE=glibc-compat20 guess I should RTFM, thank you spanky
