Using MKS Lex & Yacc with MKS Toolkit
In general, MKS Lex & Yacc is fully compatible with MKS Toolkit
for System Administrators, MKS Toolkit for Developers, and MKS Toolkit
for Interoperability. It is not recommended for use with MKS Toolkit
for Professional Developers and MKS Toolkit for Enterprise Developers
due to conflicts with the versions of lex and
yacc provided with those products.
Getting the Correct Reference Page
Because all versions of the MKS Toolkit product install the plain
text reference pages for the SCO lex and yacc
utilities provided in MKS Toolkit for Professional Developers and
MKS Toolkit for Enterprise Developers, there are some issues with
viewing the correct reference pages.
On a system with both MKS Lex & Yacc and MKS Toolkit, typing
one of the following:
man lex
man yacc
displays either the plain text reference page for the SCO utility (if
MKS Lex & Yacc was installed first) or the MKS Lex &
Yacc utility (if MKS Toolkit was installed first).
To avoid any confusion, you should use the HTML Help version of the
reference pages provided in the MKS Lex & Yacc online documentation
or for the SCO versions, the reference pages in the MKS Toolkit
Utilities Reference.
Also, the HTML Help versions of the MKS Lex & Yacc reference
pages are not viewable with the MKS Toolkit man
-h command (once again, that gives you the SCO pages from
MKS Toolkit if it is installed). You can view them as described earlier
or by typing:
%ROOTDIR%\etc\help\lyref.chm
at the Windows command prompt or:
$ROOTDIR/etc/help/lyref.chm
at an MKS KornShell, MKS Bash, or MKS C Shell command prompt.
Getting the Correct Executable
Should you choose to install MKS Lex & Yacc and either MKS Toolkit
for Professional Developers or MKS Toolkit for Enterprise Developers,
you can avoid some of the conflicts created by specifying a full path
name when you run lex or yacc.
To run the MKS Lex & Yacc versions of the utilities, type one of
the following at a Windows command prompt:
%ROOTDIR%\mksnt\lex
%ROOTDIR%\mksnt\yacc
or one of the following at an MKS KornShell, MKS Bash, or MKS C Shell
command prompt:
$ROOTDIR/mksnt/lex
$ROOTDIR/mksnt/yacc
To run the SCO versions of the utilities provided with MKS Toolkit for
Professional Developers or MKS Toolkit for Enterprise Developers,
type one of the following at a Windows command prompt:
%ROOTDIR%\bin\lex
%ROOTDIR%\bin\yacc
or one of the following at an MKS KornShell, MKS Bash, or MKS C Shell
command prompt:
$ROOTDIR/bin/lex
$ROOTDIR/bin/yacc
