When you try compiling some software (in my case it was ImageMagick), you can get this error:
error: Autoconf version 2.68 or higher is required
It means you have probably never updated autoconf on your system. It’s quite easy to fix this in some clear steps:
- Download the latest version of autoconf available – for me it was 2.69, which can be found at its official page
wget http://ftp.gnu.org/gnu/autoconf/autoconf-latest.tar.gz - Extract it to any folder:
tar xzvf autoconf-latest.tar.gz;
cd autoconf-2.69 - Run the usual sequence of commands to compile it from source (of course, you should be root to do that):
./configure
make
make install
That’s all! Pretty easy, and now you’re ready to continue with your initial installation.
