Hi Satish,
I have tried the options ex5f, but getting the same error.
The code was running without any issues long back and I was using petsc
ver 3.9 using gcc 12.X.X.
My makefile flags are :
FFLAGS = -march=native -O3 -pipe -ffree-form -cpp -ffree-line-length-none \
-Wall -Wextra -Wtabs -Wintrinsics-std -Wsurprising
-Waliasing \
-Wno-unused-parameter -Wno-unused-dummy-argument \
-D$(MODEL) \
-DVERSION=\"$(GIT_VERSION)\" \
-I$(PETSC_DIR)/include
FPPFLAGS = -cpp -E -dM -C -P -D$(MODEL)
LDFLAGS = -lpetsc -L$(PETSC_DIR)/lib
LDFLAGS += -Wl,-rpath=$(PETSC_DIR)/lib
Have i missed anything?
Regards,
Kiran
