Jeremy,

>Institution: Ensco Inc
>Package Version: 6.2.1
>Operating System: Mandrakelinux 10.1
>Hardware Information: hp pavilion ze5000
>Inquiry: When running the ./configure it couldn't finish because of
>some yacc.  What is this yacc?

'yacc' stands for yet another compiler compiler.  Here is the first part
of the description of yacc from its man page under AIX 5.1:

DESCRIPTION
     The yacc command converts a context-free grammar into a  set
     of  tables  for  a simple automaton that executes an LALR(1)
     parsing algorithm.  The grammar may be ambiguous;  specified
     precedence rules are used to break ambiguities.

     The output file, y.tab.c, must be compiled by the C compiler
     to  produce  a  function  yyparse().   This  program must be
     loaded with the lexical analyzer program, yylex(),  as  well
     as  main()  and yyerror(), an error handling routine.  These
     routines must be supplied by the user; the lex(1) command is
     useful for creating lexical analyzers usable by yacc.

>I have installed LDM several times
>before on linux 9.3 and less and haven't had any problems.

This would indicate that when the 9.3 OS was installed, it was done
specifying a full development environment.  Apparently, your Mandrake
10.1 installation was not done specifying that you wanted a full
development environment.  The simplest thing to do is figure out
which RPM (I believe that Mandrake uses RPMs; please correct me if
I am incorrect) contains yacc and then install it (as 'root').

>Of course
>this time I am installing it under a different user then ldm.

The user name shouldn't make a difference _unless_ the PATH for the
user does not include the directories containing the tools needed
for the build.

As the user your are trying to install LDM under, use the 'locate'
command to see if yacc can be found:

locate yacc

If it can be found, it means that your PATH is incomplete.  At this point
simply update your PATH, remove files created by the 'configure' script
and then start your LDM build from scratch.  This process should not take
more than a couple of minutes.

>Any suggestions would be greatly appreciated.  Thanks.

Please see comments above.

Cheers,

Tom Yoksas

Thanks I found a yacc rpm for mandrake and I also had to down load the
flex rpm for the make portion of ldm.  It is up and running fine.
