uClinux_dep分析记

uClinux－dist目录
dep:
    @if [ ! -f $(LINUXDIR)/.config ] ; then \
        echo "ERROR: you need to do a 'make config' first" ; \
        exit 1 ; \
    fi
    $(MAKEARCH) -C $(LINUXDIR) dep
先检验是否产生./config，若产生则运行依赖

linux-2.4.x目录
dep-files: scripts/mkdep archdep include/linux/version.h
    scripts/mkdep -- init/*.c > .depend
    scripts/mkdep -- `find $(FINDHPATH) -name SCCS -prune -o -follow -name \*.h ! -name modversions.h -print` > .hdepend
应该是产生依赖文件

生成mkdep可执行文件
scripts/mkdep: scripts/mkdep.c
    $(HOSTCC) $(HOSTCFLAGS) -o scripts/mkdep scripts/mkdep.c
