How to solve "aclocal not found" error on Ubuntu/Linux


In this article, we will see how to solve "aclocal not found" error on Ubuntu/Linux. Sometimes you may have noticed that while trying to install a package through source code there will be multiple dependent packages and tools which are required to be available in the System. Without having all the prerequisites fulfilled, the installation will fail at the configuration step itself. In my case, similar thing happened when I was trying to install BBC micro simulator application through source code.

While checking the configuration I noticed that aclocal is not available in my system due to which it was showing "aclocal not found" error. It is also possible that you will get "aclocal not found" error due to number of other reasons as well. If you are also getting this error due to any reasons then you can follow the steps mentioned in below section to solve that error.

In my case, when I tried to configure and compile the BBC Micro emulator code in Ubuntu 20.04 LTS System then I ended up getting "aclocal not found" error on the output as you can see below.

cyberithub@ubuntu:~/b-em$ ./ && ./configure && make
./ 17: aclocal: not found
aclocal failed

To fix the above problem, we need to install automake package and other dependencies by using sudo apt-get install automake command as shown below.

cyberithub@ubuntu:~/b-em$ sudo apt-get install automake

After installing the package, I again tried to configure and compile the code using ./ && ./configure && make command. This time it got completed successfully as you can see below.

cyberithub@ubuntu:~/b-em$ ./ && ./configure && make installing 'etc/compile' installing 'etc/config.guess' installing 'etc/config.sub' installing 'etc/install-sh' installing 'etc/missing'

Most of the time installing automake package solves the problem but in some cases you might see the same error popping up again. In those cases, you need to check and verify if the aclocal is getting detected by your System or not. If the automake package is installed on some other path then you need to add that path to the global PATH environment variable to make it available across all the user profiles in the System. Hope above solution works for you as well. Please let me know your feedback in the comment box !!
