Comment 1 Dmitry Melekhov 2002-06-07 05:18:29 UTC

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!

Comment 2 Jakub Jelinek 2002-06-07 14:59:19 UTC

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 are).
I've fixed this in:
http://sources.redhat.com/ml/libc-hacker/2002-06/msg00008.html
Will work on a 7.3 errata for this next week.

Comment 3 Jakub Jelinek 2002-07-11 09:43:27 UTC

This was fixed in glibc-2.2.5-36.
