c - 在使用 AM_LDFLAGS 的项目的 makefile 中编写依赖关系规则

Question

我想为我的项目编写依赖关系规则，因为项目包含 src 目录，并且 src 文件夹包含依赖于 file1.c 的 main.c 和 file1.c 依赖于 file2.c我有非标准库目录和非标准包含目录我使用 AM_CFLAGS =/path 包含目录和 AM_LDFLAGS = lib 目录路径我想制定通用依赖规则我尝试过玩

depend:
     makedepend $(AM_CFLAGS) $(SRC_DIR) 

但它提示它使用的库，所以我想制定通用依赖关系规则，以便在任何人添加新文件或更改文件中的某些内容时不重写规则

这是 src 目录的 makefile:

   program_NAME := SRR

    AM_CPPFLAGS = \
       -DPACKAGE_LOCALE_DIR=\""$(localedir)"\" \
       -DPACKAGE_SRC_DIR=\""$(srcdir)"\" \
       -DPACKAGE_DATA_DIR=\""$(pkgdatadir)"\"


  bin_PROGRAMS = SRR_AutoProject

  program_INCLUDE_DIRS := /usr/bin/SRR__bin

  program_LIBRARY_DIRS := /usr/lib/SRR__lib

  AM_CFLAGS = 

  AM_CFLAGS += $(foreach includedir,$(program_INCLUDE_DIRS),-I$(includedir))

  program_lib2 := \
         SRR___wrapper_library__ml \
         srrynarray \
         prhash \
         prhash_pic \
         prhistogram \
         prlistofarrays \
         vreo_wrapper_library 
 AM_LDFLAGS = 

 AM_LDFLAGS += $(foreach librarydir,$(program_LIBRARY_DIRS),-L$(librarydir))

 AM_LDFLAGS += $(foreach library,$(program_lib2),-l$(library))

 SRR_AutoProject_SOURCES = \
         main.c \
         file1.c \
         file2.c

  depend: 
     makedepend $(AM_CFLAGS) $(SRR_AutoProject_SOURCES)

根目录的makefile如下所示:

    SUBDIRS = src

    SRR_AutoProjectdocdir = ${prefix}/doc/PRDSL_AutoProject
    SRR_AutoProjectdoc_DATA = \
          README\
          COPYING\
          AUTHORS\
          ChangeLog\
          INSTALL\
          NEWS


    INTLTOOL_FILES = intltool-extract.in \
           intltool-merge.in \
           intltool-update.in

    EXTRA_DIST = $(PRDSL_AutoProjectdoc_DATA) \
           $(INTLTOOL_FILES)

      DISTCLEANFILES = intltool-extract \
           intltool-merge \
           intltool-update \
           po/.intltool-merge-cache


     # Remove doc directory on uninstall
      uninstall-local:
           -rm -r $(PRDSL_AutoProjectdocdir)

here is a makedepend rule, extracted from:
<http://www.cs.swarthmore.edu/~newhall/unixhelp/howto_makefiles.html>

INCLUDES := -I/home/newhall/include  -I../include
SRCS := $(wildcard:*.c)

.PHONY: depend

depend: $(SRCS)
    makedepend $(INCLUDES) $^

# DO NOT DELETE THIS LINE -- make depend needs it
