[petsc-users] Preprocessor definition in makefile for IBM XL Fortran Compiler

[Danyang Su]

Hi All,

Does any one know how to use the preprocessor definition flags for IBM XL
Compiler on  IBM BG/Q system?

I can use FPPFLAGS (below) for Intel fortran compiler and Gfortran, but IBM
XL Fortran compiler cannot recognise it. I also tried to use FPPFLAGS_IBMXL
(below) but without success.

How can I set the FPPFLAGS for IBM XL Compiler? It seems a little painful
to support it.

Thanks,

Danyang

#makefile
include ${PETSC_DIR}/conf/variables
include ${PETSC_DIR}/conf/rules
SRC =./../../
FPPFLAGS = -DLINUX -DRELEASE -DPETSC -DMPI
FPPFLAGS_IBMXL = -WF,-DLINUX -WF,-DRELEASE -WF,-DPETSC -WF,-DMPI
DLIB =
# Note: Order of the following code files is the same with that in visual
fortran project buildlog
SOURCES = $(SRC)common.o\
$(SRC)input.o\
$(SRC)model.o\
......
example: $(SOURCES) chkopts
        -${FLINKER} $(FPPFLAGS_IBMXL) -o example $(SOURCES) ${PETSC_LIB}
${DLIB}
