Building Issues on BGL

[Niall Moran]

Hi,

I am having issues compiling the latest version of PETSc on a Bluegene/ 
L machine. I am using the IBM compilers version
V1R3M3_420_2007-071023.

The error I am getting during compile is

...../petsc-3.0.0-p8/src/sys/viewer/impls/socket
"send.c", line 105.12: 1540-0274 (S) The name lookup for  
"gethostbyname" did not find a declaration.

"SO_REUSEADDR" did not find a declaration.
/usr/bin/ar: send.o: No such file or directory

The config file I am using is below. I have tried commenting out some  
of the variables defined in the petscconf.h but to no avail. The  
variables I tried were
PETSC_USE_SOCKET_VIEWER
PETSC_HAVE_SYS_SOCKET_H
PETSC_HAVE_GETHOSTBYNAME
PETSC_HAVE_SOCKET

I never encountered such issues with PETSc pre release 3. Any help is  
greatly appreciated.

Regards,

Niall.
