我在使用库的fortran上编写程序。
为了进行编译,我使用了简单的shell脚本,一切都很好:

gfortran -c mod_input.f90 mod_cpp.f90 mod_data.f90 main.f90 b_coils.f

gfortran -o主mod_input.o mod_cpp.o mod_data.o main.o b_coils.o libspline.a -lstdc ++

(libspline.a-用C ++编写的库)

现在,我想使用makefile代替shell脚本,但是不知道如何正确编写它。

生成文件:

target = main
srcdir = src/
objdir = obj/
targetdir = run/

FORT = gfortran
mflag = module
FORTFLAGS =
LDFLAGS = -lstdc++

MKLPATH =/home/gatto/Desktop/ray_u3/src
LIBDIR  =-L$(MKLPATH)
LIBS = -lspline
MODDIR = obj/

# Ray sources
sources = mod_input.f90 mod_cpp.f90 mod_data.f90  main.f90 b_coils.f


# objects
objects  = $(patsubst %.for,%.o,$(filter %for,$(sources)) )
objects += $(patsubst %.f90,%.o,$(filter %f90,$(sources)) )

# main target
build:$(targetdir)$(target)

# build rules
$(targetdir)$(target):$(addprefix $(objdir),$(objects))
    @echo === build $@ ===
    $(FORT) $(FORTFLAGS) $(LDFLAGS) $(LIBDIR) -o $@ $(LIBS) $^

#compilation target
compile :$(addprefix $(objdir),$(objects))

# compilation rules
$(objdir)%.o : $(srcdir)%.f90
    @echo === compile $< ===
    $(FORT) -c $(objdir) $(FORTFLAGS) -o $@ $<

$(objdir)%.o : $(srcdir)%.f
    @echo === compile $< ===
    $(FORT) -c $(objdir) $(FORTFLAGS) -o $@ $<


# cleaning rules
cleanobj:
    -rm $(objdir)*.o $(objdir)*.mod
cleantarget:
    -rm $(targetdir)$(target)

cleanall:cleanobj cleantarget

.PHONY: compile build cleanall cleanobj cleantarget


输出:

最佳答案

我建议您使用automake(和autoconf)。它确实有大量的metatag,但是对于简单的程序而言,它的编写速度更快,并且在大多数情况下,您可能会发现自己所做的改动很小(例如filename)。

这是我的autoconfautomake用于类似项目的输入,该项目仅使用lapack而不是mkl

configure.ac

#AC_PREREQ(2.69)
AC_INIT([src], [0.1],
    [],
    [mftc],
    [])
AC_CONFIG_AUX_DIR([build-aux])
AC_CONFIG_HEADERS([config.h])
AC_CONFIG_MACRO_DIR([m4])

AM_INIT_AUTOMAKE([1.9.6 dist-bzip2 subdir-objects foreign])

AC_SEARCH_LIBS([dsyev_], [lapack], ,AC_MSG_ERROR([No LAPACK library]))
AC_OPENMP
FCFLAGS="$OPENMP_FFLAGS "
AC_PROG_FC([gfortran, ifort])
AC_CHECK_PROG([DEPF90_CHECK],[makedepf90],[yes],[no])
AM_CONDITIONAL([FOUND_MAKEDEPF90], [test "x$DEPF90_CHECK" = xyes])
AC_CONFIG_FILES([
         Makefile
         ])
AC_OUTPUT


Makefile.am

bin_PROGRAMS =  mftc
mftc_SOURCES = src/mftc.f90  src/parse.f90 src/sort.f90
depend depend.mk:
    makedepf90 $(mftc_SOURCES) >depend.mk
@am__include@ @[email protected]@am__quote@
mftc_LDADD =
EXTRA_DIST=depend.mk autogen.sh Makefile.am
CLEANFILES =*.mod  *.log


depend depend.mk取决于makedepf90程序,该程序在大多数linux平台上都可用。该程序负责相关性(即,在程序之前先编译模块)。

用法
如果您对LAPACK没问题,那么configure.ac中没有任何更改。将_SOURCES行更改为正确的文件名。
 现在,它在终端的3个命令:

 $autoconf
 $./configure
 $make


当然,您还需要安装automake和autoconf。

希望这可以帮助
