[M3devel] building m3gdb on AMD64_LINUX

[Rodney M. Bates]

On my AMD64_LINUX machine (Ubuntu 8.04.2), on which m3gdb builds, yacc
is circuitously symlinked  to a script that executes /usr/bin/bison -y.

In any case, usually, there is no need to execute yacc when building 
(m3)gdb,
because its output is already present and newer than yacc's input, in 
this case,
c-exp.y.  I think this is the way it is in the CVS repository.  Did some 
dates
in your source copy get touched?

I have no idea where the c-exp.t file it wants is supposed to come from.
In a brief look, I didn't find any reference to a *.t file at all, 
either in the script
m3gdb/gdb/ylwrap, nor in the yacc man page (which actually leads to the
bison man page on my machine).   Maybe original yacc  does something 
with it. 
I would have thought ylwrap would have been written to work with a number
of varieties of yacc and equivalents. 

Do you have a copy of c-exp.y?

I suspect having a newer c-exp.c than c-exp.y will circumvent this 
problem, but
of course we probably want it set up to work when c-exp.c needs to be 
rebuilt.
