Hello, Ishita.

It might be a problem with your environment.  You need to ensure the
architecture-specific directory in the EPICS Base bin directory is
in your shell's command search path.  For example, with EPICS Base
installed to /opt/epics-base-3.14.12.5 on OS X, I would need the
following directory in my shell's command search path:

  /opt/epics-base-3.14.12.5/bin/darwin-x86

In Bash, this can be achieved by adding the directory to the PATH
environment variable.  You can then (in Bash) use the "which" command to
see if the shell can find it:

  $ which makeBaseApp.pl

However, I'm a little confused by the error message you reported:

  bash: makeBaseApp: command not found...

The command is makeBaseApp.pl (note the ".pl" extension), not
makeBaseApp, so I'm not sure where that "makeBaseApp" is coming from.

On OS X, the makeBaseApp.pl program uses the following shebang line:

  #!/usr/bin/env perl

So, in this case, it requires /usr/bin/env, and it requires that the
perl command can be found on the command search path of the shell
invoking makeBaseApp.pl.

This could be different on your system.  What platform are you on?

Lewis
