[petsc-users] Reg : Configuring PETSc on Cygwin

[Satish Balay]

1. please post issues to either petsc-users [public list] or
petsc-maint [private list] - but not both. And please do not bcc:
e-mails to the list. They will not get posed.

2. configure.log attached is a link file - the actual file shold
be in PETSC_DIR/PETSC_ARCH/conf/

3.when specifying PATHs to configure - use cygwin path notation. i.e

--download-fblaslapack=/cygdrive/D/Software/Cygwin/package/fblaslapack-3.4.2.tar.gz

4. you can install blas/lapack from cygwin [liblapack-devel] - and use it. Similarly with openmpi

5. You should not need/use  '--with-batch --ignore-cygwin-link' options with cygwin/gnu compilers.
