fixing error: undefined macro: AC_PROG_LIBTOOL

May 17th, 2007 by Lawrence David

i was getting this error while trying to compile faad2:

configure.in:14: error: possibly undefined macro: AC_PROG_LIBTOOL
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
autoreconf: /usr/bin/autoconf failed with exit status: 1

i made this error go away by install “libtool:”

$ sudo apt-get install libtool

————— EXPLANATION —————–

that’s right
to fix the error mentioned you need to install libtool
but that’s not all

it might happen that you have to install it from sources
in this case you MUST SPECIFY prefix for configure script:
./configure –prefix=/usr

otherwise you have to deal with paths somehow to make aoutoconf see your thirdparty macros, which libtool contains

PS/ took an hour to find it out myself
anyway thanx for giving a tip

Very glad that I stumbled on your post. Your answer was helpful, thank you.

I’d like to say, however, that a “possibly undefined macro” doesn’t even *remotely* spell “you need libtool” to me.

One more reason I truly dislike automake/autoconf.
