Hi all,

I installed the Petsc 3.1 recently and when I tried to make my program using Petsc 3.1 it said:

In file included from /home/rlchen/soft/petsc-3.1-p4/include/petscsys.h:1467,
牋牋牋牋牋牋牋牋 from /home/rlchen/soft/petsc-3.1-p4/include/petscis.h:7,

牋牋牋牋牋牋牋牋 from joab.c:54:
/home/rlchen/soft/petsc-3.1-p4/include/petscerror.h:81:1: warning: "__SDIR__" redefined
<command line>:1:1: warning: this is the location of the previous definition
.
.
.
.
I never defined the "__SDIR__" and I do not know why it said I redefined "__SDIR__".
But I can run my program on Petsc 3.0.

Can anyone tell me how to fix this problem? Thank you!

Best,

Rongliang
