[petsc-users] cannot open source file "petsc.h"

[Satish Balay]

You an try the following:

- remove
PETSC_INCLUDE=/cosma/home/dp092/dc-evst1/petsc/include
PETSC_LIB=/cosma/home/dp092/dc-evst1/petsc/lib

- remove
include ${PETSC_DIR}/lib/petsc/conf/rules
include ${PETSC_DIR}/lib/petsc/conf/test

- remove
petsc.pc := $(PETSC_DIR)/$(PETSC_ARCH)/lib/pkgconfig/petsc.pc

i.e only keep:
include ${PETSC_DIR}/lib/petsc/conf/variables

You have:

LINK += $(PETSC_LIB)

Similarly you need:
cxxcppflags += $(PETSC_CXXCPPFLAGS)

The code using PETSC compiles using GNUMakefile and so using instructions on the website and in Makefile.user I added the following lines to the make file:
