Some people don't want RPATH. It was discussed here.
https://mid.mail-archive.com/CAEymZafiQtwKDxh0myQ1LD_uByGKv5JyQ9PGzK3ZTmFPcOR=k...@mail.gmail.com
The RPATH flag is stored in a variable ldflag_rpath in PETSc.pc so you
can add it to PETSc paths, as done in this sample makefile.
PETSc.pc := $(PETSC_DIR)/$(PETSC_ARCH)/lib/pkgconfig/PETSc.pc
CC := $(shell pkg-config --variable=ccompiler $(PETSc.pc))
CXX := $(shell pkg-config --variable=cxxcompiler $(PETSc.pc))
FC := $(shell pkg-config --variable=fcompiler $(PETSc.pc))
CFLAGS := $(shell pkg-config --variable=cflags_extra $(PETSc.pc)) $(shell
pkg-config --cflags-only-other $(PETSc.pc))
FFLAGS := $(shell pkg-config --variable=fflags_extra $(PETSc.pc))
CPPFLAGS := $(shell pkg-config --cflags-only-I $(PETSc.pc))
LDFLAGS := $(shell pkg-config --libs-only-L --libs-only-other $(PETSc.pc))
LDFLAGS += $(patsubst -L%, $(shell pkg-config --variable=ldflag_rpath
$(PETSc.pc))%, $(shell pkg-config --libs-only-L $(PETSc.pc)))
LDLIBS := $(shell pkg-config --libs-only-l $(PETSc.pc)) -lm
print:
@echo CC=$(CC)
@echo CFLAGS=$(CFLAGS)
@echo CPPFLAGS=$(CPPFLAGS)
@echo LDFLAGS=$(LDFLAGS)
@echo LDLIBS=$(LDLIBS)
