#   This script generates the Makefile that compiles the library.
#   The ~OUTPUT~ variable contains the name of the generated Makefile,typically

# We start by tangling all the org-mode files.


${QMCKL_ROOT}/tools/tangle.sh *.org



# Then we create the list of ~*.o~ files to be created, for library
# functions:


OBJECTS="qmckl_f.o"
for i in $(ls qmckl_*.c qmckl_*f.f90) ; do
    FILE=${i%.*}
    OBJECTS+=" ${FILE}.o"
done >> $OUTPUT



# for tests in C:


TESTS=""
for i in $(ls test_qmckl_*.c) ; do
    FILE=${i%.c}
    TESTS+=" ${FILE}.o"
done >> $OUTPUT



# and for tests in Fortran:


TESTS_F=""
for i in $(ls test_qmckl_*_f.f90) ; do
    FILE=${i%.f90}
    TESTS_F+=" ${FILE}.o"
done >> $OUTPUT



# Finally, we append the rules to the Makefile
