libtoolize needed ¶Libtool comes with a tool called libtoolize that will
install Libtool’s supporting files into a package. Running this
command will install ltmain.sh. You should execute it before
aclocal and automake.
People upgrading old packages to newer autotools are likely to face
this issue because older Automake versions used to call
libtoolize. Therefore old build scripts do not call
libtoolize.
Since Automake 1.6, it has been decided that running
libtoolize was not Automake’s business. Instead, that
functionality has been moved into the autoreconf command
(see Using autoreconf in The Autoconf Manual). The autoreconf command saves you
from having to figure out which infrastructure scripts to run in what
order. Augmenting existing bootstrap or autogen.sh
scripts with a call to autoreconf should also free you from
any similar incompatible change in the future.
