[petsc-users] Compilation error

[Jin, Shuangshuang]

Thanks, your comment helps. After loading a newer version of gcc/4.6.2, the code got compiled successfully.

Thanks,

You must be using a very old "petsc-dev".  Likely scenario here is that you have changed environments from when you configured, and now this older version of gcc (the Intel compiler changes its dialect based on which gcc it finds in path) has a dialect that doesn't support arguments to attribute deprecated.  This was so common that I unconditionally turned off use of the argument to attribute deprecated.  (Yes, this is worse for users that have a stable environment or don't use Intel compilers, but Intel's indirect environment-dependence causes the unacceptable breakage above so we had to work around it somehow.)
