No, it doesn't. It probably uses glibc 2.3.2. > Do the glibc version have to be identicaly? No. UNIX machines in general support backwards compatibility, but not "forward" compatibility. That means, that you can expect a binary compiled on an older machine to continue working fine on a newer one (newer glibc continues to support "backward" binaries), but you can *not* expect a binary built on newer machine to work on an older one (the older glibc has no clue how to support features which haven't been invented yet). > I have read that upgrading/downgrading glibc is a heavy task. It's not necessarily "heavy" if you use precompiled packages, but building your own requires extreme care -- you can easily make your system un-bootable if you make a single mistake. > Is there a compiler switch to toggle a specific glibc version or to make the > binary glibc conform. No. > Do you know another solution to the problem? There are three general solutions (listed in order of increasing difficulty): 1. Build on the oldest release of glibc you plan to support (we build on ancient RedHat 6.2 with glibc-2.1, and it runs *everywhere*). 2. Use Autopackage (http://autopackage.org/apbuild-apgcc.php) 3. Use x86-glibc-2.4 -> x86-glibc-2.3.2 cross-gcc (see http://www.kegel.com/crosstool). Cheers, -- In order to understand recursion you must first understand recursion.
