Libtool library used but `LIBTOOL' is undefined?
centos5, ffmpeg
Solution
The error is telling you that either `libtool` is not installed, or that you are not checking for it in `configure.ac`. Add the line `LT_INIT` in `configure.ac`. If `autoreconf` then complains that it doesn't know what `LT_INIT` is, you should either install libtool, upgrade your installation of libtool or use the deprecated `AC_PROG_LIBTOOL` in configure.ac. (`AC_PROG_LIBTOOL` should be replaced by `LT_INIT` in newer projects.)
Problem
Im trying to install ffmpeg on my server. Im unsing centos 5. When I try to install libfdk_aac I get the following error ``` ` autoreconf: Entering directory `.' autoreconf: configure.ac: not using Gettext autoreconf: running: aclocal --force -I m4 autoreconf: configure.ac: tracing autoreconf: configure.ac: not using Libtool autoreconf: running: /usr/bin/autoconf --force autoreconf: configure.ac: not using Autoheader autoreconf: running: automake --add-missing --copy --force-missing Makefile.am:31: Libtool library used but `LIBTOOL' is undefined Makefile.am:31: Makefile.am:31: The usual way to define `LIBTOOL' is to add `AC_PROG_LIBTOOL' Makefile.am:31: to `configure.ac' and run `aclocal' and `autoconf' again. Makefile.am: C objects in subdir but `AM_PROG_CC_C_O' not in `configure.ac' autoreconf: automake failed with exit status: 1 ` ``` If i type which libtool I get /usr/bin/libtool, so i think libtool is installed. So im not sure why this error is happening. Thanks for any advice
