Hi All,

My code has some FPP. It works fine in PETSc 3.18 and earlier version, but stops working in the latest PETSc-Dev. For example the following FPP STANDARD_FORTRAN is not recognized.

#ifdef STANDARD_FORTRAN

1 format(15x,1000a15)

2 format(1pe15.6e3,1000(1pe15.6e3))

#else

1 format(15x,<ncol>a15)   

2 format(1pe15.6e3,<ncol>(1pe15.6e3))

#endif

In the makefile, I define the preprocessor as PPFLAGS.

PPFLAGS := -DLINUX -DRELEASE -DRELEASE_X64 -DSTANDARD_FORTRAN

…

exe: $(OBJS) chkopts

                -${FLINKER} $(FFLAGS) $(FPPFLAGS) $(CPPFLAGS) -o $(EXENAME) $(OBJS) ${PETSC_LIB} ${LIS_LIB} ${DLIB} ${SLIB}

Any idea on this problem?

All the best,
