I've mentioned this before. Does anyone have the same problem as me? When using a Synology NAS (DS1010+ or the DS508) with the latest DSM 4.2 Beta but also the previous DSM 4.1 on the DS1010+ (i386) AND the DSM 4.0 which is running on the DS508 (ppc) (cannot upgrade to newer version) I get this. ./SyncApp_i386-1.0.75: /lib/libc.so.6: version `GLIBC_2.4' not found (required by ./SyncApp_i386-1.0.75) I get this with 1.0.75, 1.0.63 and 1.0.62. I cannot upgrade my Glibc to a 2.4 variant. The information on the libc.so.6 is: GNU C Library stable release version 2.3.6, by Roland McGrath et al. Copyright (C) 2005 Free Software Foundation, Inc.

Someone out there must also have this problem. I believe on newer nasses of Synology there must be a newer version of glibc installed. Can someone please verify this? Enter this on your commandline: /lib/libc.so.6 and post the output. Can someone build me a version for 2.3 glibc to test on my nasses? Or build me a static linked version. I might think that when the SyncApp gets released, lots of people want to run this on their older nas too.
