Thanks!

so what can I do to compile if I want to use PETsc in VS2010?

I have tried using g++:

./configure --with-cxx=g++ --with-fc=0 --download-f2blaslapck --download-mpich

then

make PETSC_ARCH=arch-mswin-cxx-debug all
make PETSC_ARCH=arch-mswin-cxx-debug test

it shows:

Using PETSC_DIR=/petsc-3.3-p6 and PETSC_ARCH=arch-mswin-cxx-debug
/usr/bin/sh: line 20: 10916 Segmentation fault  " some path here"(I omitted)
Possible error running C/C++ src/snes/examples/tutorials/ex19 with 1 MPI process

See http://www.mcs.anlgov/petsc/documentation/faq.html

You can't mix gcc here and VS2010 later because they are not compatible.

Configure tests whether the compiler supports __builtin_expect.  There
are probably many other incompatibilities.
