autoconf & automake

problem 1

when you use automake to prodeuce Makefile,and you get error like:

configure.ac:11: error: possibly undefined macro: AC_PROG_LIBTOOL
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.

first ,make sure that the related lib is installed ,and then use:

# aclocal –print-ac-dir

check the default searcj path for aclocal,make sure the missing macro is included in the default path.if not,you can use:

#aclocal -I path

use the command to add the define file to the aclocal search path.or ,you can modify the default search path ,by modify /usr/share/aclocal/dirlist file ,append this line:

/usr/share/aclocal
/**/your path/
