about PETSC installation

[Yixun Liu]

Thanks.
If I turn off Fortran, does PETSC work well? I think PETSC depends on Fortran because it use LAPACK.

Yixun

    Hi,
    Thanks for your help.

    Firstly I want to know if the error is caused by no Fortran on my computer?

  Yes, you can turn of Fortran using --with-fc=0.

    BTW, could you tell me more about the configure option, which you suggest?

    Best regards,
