How to install Autoconf, Automake and related tools on Mac OS X from source?
Update: Just use Homebrew to install these packages and move on with life.
Install Homebrew and just install the autoconf, automake and libtool packages like this:
brew install autoconf automake libtool
When I wrote this answer about 3+ years ago, it was to correct a previous answer that was outdated, link-only and vague in explanation. At that time I preferred to use raw source compilation on macOS for a task like this rather than a package manager like Homebrew because I simply found Homebrew and MacPorts to be a tad immature back then.
Now I use Homebrew (aka brew) on macOS as regularly as I use apt-get on Ubuntu and yum on CentOS. I would recommend avoiding compiling anything from raw source code on macOS unless you really have no choice.
Old answer content below for reference purposes.
I realize this question is about 3+ years old, but the accepted answer is a link only answer and that link is now dead. And the other answer is technically correct, but it still does not explain the actual hands-on process required to install the GNU versions of autoconf, automake and libtool in Mac OS X.
First, Xcode—since at least version 4.3 I believe—no longer includes the GNU versions of autoconf, automake and libtool. This doesn’t mean you can’t install GNU tools on your own. And here is how.
I’ve used this process on Mac OS X 10.6 (Snow Leopard), 10.7 (Lion), 10.8 (Mountain Lion) and 10.9 (Mavericks) without issue.
Install Xcode and Xcode command line tools.
The first prerequisite is to have Xcode installed along with the Xcode command line tools as well. Chances are if you need autoconf, automake and libtool installed, you already have Xcode and the command line tools installed, but just pointing that out for those who don’t have that setup yet.
Now, onto the show! Just note that version numbers of downloads are based on what is current (as of April 2015) and works well as of the time of this post. Adjust to other versions if you need to:
Install autoconf 2.69.
Set the working directory to your home directory:
cd
Get the source code and decompress it:
curl -O -L http://ftpmirror.gnu.org/autoconf/autoconf-2.69.tar.gz
tar -xzf autoconf-2.69.tar.gz
Go into the uncompressed source code directory:
cd autoconf-*
Run the configure script on the source code:
./configure
Now run make to compile it:
make
Now install it:
sudo make install
Check the newly installed autoconf version to confirm all went well:
autoconf --version
Response should be something like this:
autoconf 2.69
Install automake 1.15.
Set the working directory to your home directory:
cd
Get the source code and decompress it:
curl -O -L http://ftpmirror.gnu.org/automake/automake-1.15.tar.gz
tar -xzf automake-1.15.tar.gz
Go into the uncompressed source code directory:
cd automake-*
Run the configure script on the source code:
./configure
Now run make to compile it:
make
Now install it:
sudo make install
Check the newly installed automake version to confirm all went well:
automake --version
Response should be something like this:
automake 1.15
Install libtool 2.4.6.
Set the working directory to your home directory:
cd
Get the source code and decompress it:
curl -OL http://ftpmirror.gnu.org/libtool/libtool-2.4.6.tar.gz
tar -xzf libtool-2.4.6.tar.gz
Go into the uncompressed source code directory:
cd libtool-*
Run the configure script on the source code:
./configure
Now run make to compile it:
make
Now install it:
sudo make install
Check the newly installed libtool version—via the man page—to confirm all went well:
man libtool
On the first page of the man page there should be something like this:
libtool - manual page for libtool 2.4.6
Just use Homebrew. It compiles everything for you. It worked like a charm for me.
brew install autoconf automake libtool
If you install autoconf from the git repository, you will need automake. However, if you instead download a distribution tarball for autoconf, you will not have that dependency. You should always install from a distribution tarball, and not from a vcs. In other words, if you want to install autoconf from source, just install it from source! But realize that "install from source" means "install from a distribution tarball"; it does not mean "install from git".
