undefined reference to `libint2_*`

[uovie]

Dear libint developers:

I meet a problem when compiling "tests/hartree-fock/hartree-fock.cc". When running make check1, it returns ...make: Nothing to be done for 'check1'.. So, I write a new Makefile

CC      := g++
INCL    := /usr/local/libint/2.5.0/include
LIBS    := /usr/local/libint/2.5.0/lib

TARGETS := HF
OBJ     := hartree-fock.o
DEPS    := 

.PHONY: all clean

all: $(TARGETS)

clean:
    rm -f $(OBJ)

$(OBJ): %.o : %.cc $(DEPS)
    $(CC) -I $(INCL) -L $(LIBS) -c $< -o $@

$(TARGETS): $(OBJ)
    $(CC) $^ -o $@

to carry out the compile procedure. However, it fails with errors in the linking step:

g++ hartree-fock.o -o HF
/usr/bin/ld: hartree-fock.o: in function `libint2::detail::__initializer::__initializer()':
hartree-fock.cc:(.text._ZN7libint26detail13__initializerC2Ev[_ZN7libint26detail13__initializerC5Ev]+0xd): undefined reference to `libint2_static_init'

... ...

I do not know how to solve it and correctly compile it. Looking forward to your reply.

Sincerely, Haoyu Lin

It has been solved with the Makefile

CC      := g++
INCL1   := /usr/local/libint/2.5.0/include
INCL2   := /usr/local/libint/2.5.0/include/libint2
LIBS    := /usr/local/libint/2.5.0/lib

TARGETS := HF
OBJ     := hartree-fock.o
DEPS    := 

.PHONY: all clean

all: $(TARGETS)

clean:
    rm -f $(OBJ)

$(OBJ): %.o : %.cc $(DEPS)
    $(CC) -c $< -o $@ -I $(INCL1) -I $(INCL2) -lint2 -L $(LIBS)

$(TARGETS): $(OBJ)
    $(CC)  $^ -o $@ -I $(INCL1) -I $(INCL2) -lint2 -L $(LIBS)

Thanks!
