Description Frank LeFevre 2003-11-04 18:18:21 UTC 
The following has be reported by IBM LTC:  
Missing symbol in compat-libstdc++ library, needed for DB2
Hardware Environment: z990

Software Environment: RHEL 3 GA and DB2 V8.1

Steps to Reproduce:
1.[root@rhel30 lib]# nm -o /usr/lib/libstdc++-3-libc6.2-2-2.10.0.so 
|  grep
  __udiv_w_sdiv
  [root@rhel30 lib]# nm -o /usr/lib/libstdc++-3-libc6.2-2-2.10.0.so 
|  grep
  udiv
  
Actual Results:
  libstdc++-3-libc6.2-2-2.10.0.so:         U __udivdi3@@GLIBC_2.0

Expected Results:
  libstdc++-3-libc6.2-2-2.10.0.so:0002de94 T __udiv_w_sdiv

Additional Information:
Comment 1 Jakub Jelinek 2003-11-07 00:58:46 UTC 
__udiv_w_sdiv is certainly not part of the libstdc++ ABI, just a symbol
from libgcc.a exported from the library as a side effect of its implementation.
Programs and shared libraries should be getting their own copies
from libgcc.a.
Anyway, I've forced it by -Wl,-u,__div_w_sdiv into libstdc++-3-libc6.2-2-2.10.0.so
on s390.
Can you please test:

?
Comment 2 Frank LeFevre 2003-11-07 21:38:38 UTC 
This appears to have fixed our problem. The instance was created and 
we were able to stop and start db2. Was a bit confused by the compat-
gcc file though. Was that there just to provide us the source? We did 
a rpmbuild -bb on the spec and it only built the compat-libstdc rpm, 
not compat-gcc. Thanks.
Comment 3 Florian La Roche 2003-11-24 17:09:16 UTC 
-2.95.3.38 is in our current trees, so that should be ok. Setting to
modified.
