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
- Extract it to any folder:
tar xzvf autoconf-latest.tar.gz;
- Run the usual sequence of commands to compile it from source (of course, you should be root to do that):
That’s all! Pretty easy, and now you’re ready to continue with your initial installation.
