Hello,
I re-installed the petsc with --download_hypre and --download_ml. The two
test examples ex19 and ex5f run successfully.
I added the libraries link in the makefile like:
-Wl,-rpath,${PETSC_DIR}/${PETSC_ARCH}/lib -L${PETSC_DIR}/${PETSC_ARCH}/lib
-lHYPRE -L/usr/lib/gcc/x86_64-redhat-linux/4.4.7 -lmpichcxx -lstdc++ \
-Wl,-rpath,${PETSC_DIR}/${PETSC_ARCH}/lib -L${PETSC_DIR}/${PETSC_ARCH}/lib
-lml -L/usr/lib/gcc/x86_64-redhat-linux/4.4.7 -lmpichcxx -lstdc++ \
However, the compiling errors occurred:

It seems there is some library link I missed in the makefile. What should I
add? Why it didn't happen before I re-install? Thanks.
