Re: [petsc-users] create global vector in latest version of petsc

[Hengjie Wang]

Hi,

I did.
I am using GNU compiler 5.4.0. I don't know if this matters.
Thank you

Frank

    Hi,

    I update petsc to the latest version by pulling from the repo.
    Then I find one of my old code, which worked before, output errors
    now.
    After debugging, I find that the error is caused by
    "DMCreateGlobalVector".
    I attach a short program which can re-produce the error. This
    program works well with an older version of petsc.
    I also attach the script I used to configure petsc.

First, did you reconfigure after pulling? If not, please do this, rebuild, and try again.

  Thanks,

    Matt

    The error message is below. Did I miss something in the
    installation ? Thank you.
