怎么我输入 autoscan不行

777

我想写个简单的makefile
#mkdir devel
#mkare devel/hello
#cd devel/hello
#ee hello.c
#echo $0
bash
#/usr/local/bni/psh autoscan
#ls
hello.c
成功是这样的;
#ls
configure.scan hello.c

# pkg_info|grep auto
autoconf-2.57       Automatically configure source code on many Un*x platforms
automake-1.5,1      GNU Standards-compliant Makefile generator
automake-1.7.5_1    GNU automake generates input files for GNU autoconf
# pkg_info|grep perl
p5-Sort-Versions-1.4 A perl 5 module for sorting of revision-like numbers
p5-bioperl-0.7.2    A collection of Perl modules for bioinformatics
p5-postgresql-plperl-7.3.4 The most advanced open-source database available anywhere
perlsh-0.009_1      New shell made entirely out of a Perl script

why?
help me !

怎么做到最后一步没有configure   :ask :ask :ask

bash-2.05b# ./configure
bash: ./configure: No such file or directory
bash-2.05b# ls
Makefile.am     autoscan257.log configure.in    install-sh
Makefile.in     config.guess    depcomp         missing
aclocal.m4      config.sub      hello.c         mkinstalldirs
bash-2.05b#

艾~~我老是这么大意 忘了autoconf了

那些 make后面的是什么意思? 错在那里?  :ask :ask
有可能是软件的版本问题吗?
