Re: compiling ap/libapl

[Dr . Jürgen Sauermann]

    Hi,
      
      generally speaking, the APserver is looked for in two
      directories:
      
      1. the directory in which apl lives, and
      2. the subdirectory APs of that directory.
        
        Case 1. above is the normal case: both apl and APserver
        are installed in, for example, /usr/local/bin.
        Case 2. above is the developer case: apl is in src
        and APserver is in src/APs.
        
        If you copy the apl binary into some other directory and
        start it there (like directory "."
        if it is not src or the installation directory) then you
        must also copy the APserver there
        (or else apl will be unable to find it). Note that $PATH
        is not consulted in order to
        find APserver even though $PATH is
            consulted to find apl.
            
          You can start apl with command line
        option -l 37 to see how APserver is looked for.
        
        Best Regads,
        Jürgen
