I think there was a parsing part on your part when reading that (no biggie.. it happens to everyone all the time). There is a HUGE difference between: "Red Hat Enterprise Linux 5 includes compatibility libraries that enable applications built on the versions 3 and 4 to run without recompilation." and "EL5 claims to be fully compatible with binaries that were built on EL4 and 3." Fully compatible means that every library and binary would have a '-compat' from previous versions. What EL-5 has is a subset of commonly used compatibility libraries. To answer your second question, Red Hat enterprise does not ship the same version of perl in 3,4,5: RHEL-3: perl-5.8.0-98.EL3 RHEL-4: perl-5.8.5-36.el4_6.3 RHEL-5: perl-5.8.8-10.el5_2.3 That would explain part fo the differences between library sizes and versions. > and it also talks about compatibility ( under the GCC 4.1 Compiler section > ). > > "...enable applications that were previously certified on the versions 3 and > 4..." > > Maybe the keyword here is "certified" > > thanks, > > Barry > > On Mon, Jun 16, 2008 at 12:02 PM, Jos Vos <[EMAIL PROTECTED]> wrote: >> >> On Mon, Jun 16, 2008 at 11:53:34AM -0400, Barry Andrews wrote: >> >> > EL5 claims to be fully compatible with binaries that were built on EL4 >> > and >> > 3. >> >> Where is that claimed?
