undefined reference to ....

[Satish Balay]

Ah - I wasn't checking your make output closly..

Looks like you are listing your libs after petsclibs. You'll have to
list the object files - in the correct order of dependencies..

Also - looks like you are compiling & linking at the same step.. [i.e
using .o and .f90 in the same command]. Sugest crearing .o files before
linking..

i.e 

${FLINKER} -o a.out global.o  main.o ${PETSC_LIB}
