[petsc-users] compiling error after re-installation with --download_hypre

[Roc Wang]

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.
