nm: libc-2.2.5.so: no symbols
compared with Suse 8.0:

This causes SAP GUI to not start:
Cannot load shared library or some dependent library:
symbol gethostent_r, version GLIBC_2.1.2 not defined in file libc.so.6
with link reference
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Sorry, I were wrong.
I didn't know that there is /lib/i686
But, anyway, this problem exists with Sun jdk 1.3.1 and 1.4.0.
Using of IBM jdk 1.3.1 solves problem.
But there was no such problem on RH 7.2!
Even /lib/libc.so.6 has the dynamic symbol table (otherwise it would be useless),
see readelf -s /lib/libc.so.6 or nm -D /lib/libc.so.6.
The fact is that because of a bug get*ent_r@@GLIBC_2.1.2 functions are not
exported (but e.g. get*ent_r@GLIBC_2.0 are).
I've fixed this in:
Will work on a 7.3 errata for this next week.
This was fixed in glibc-2.2.5-36.
