problem with Rcmd check

Perl on Win95/Win98/WinME is limited by the capabilities of the command-line
editor. There are applications that flat-out can't use it; check the Perl
Data Language (PDL) pages for the gory details. I have personally given up
on Windows ME, though for different reasons: the worst thing that happened
to me was the Visual Studio blue-screened when trying to do post-build
commands. This is probably something to do with the lame command line
interpreter. I went out the next day and spent $330 -- $300 for Windows 2000
Professional and $30 for Red Hat Linux. I am now a happy dual-booter :-).

Thanks to some debugging by Duncan Murdoch, it looks like this is a Perl
problem on Win98/ME at least.  As far as I can tell Perl's system command
calls command.com on that system, and at times that gets caught out by
line lengths and redirections.

So please let me know which version of Windows you have.

It's pretty unpredictable, and this did work on my Win98 mini-notebook
with a very small example (ash) but the undoc check failed there.
I was able to get it all to work by changing shell using COMSPEC, but
I cannot distribute the shell I did use.  Anyone know of a reliable
shell foo.exe for Win98 that uses `foo.exe /c commands...' ?  Otherwise
I can write a wrapper for sh.  Actually, I might be able to avoid the
shell here by using a list argument for system....

You might begin to see why Guido and I changed to NT about 2 years' ago.

* creating meanscore-Ex.R ... ERROR

       ^^^^^^^^

But when I'm using the primitive command `make pkgcheck'
from c:/rw1020/rw1020/src/gnuwin32, the meanscore-Ex.R file
is successfully created and the output is correct.

I think the thing to do at this point is to run something like

rterm.exe --vanilla < meanscore-Ex.R

(except that one or both of rterm.exe and meanscore.R probably need

to

have a full path). Then watch the output and see where the error
comes from.

The error is in creating meanscore-Ex.R.  Agus Salim is asking the list
what he asked me privately a while ago.  I have no idea, and him to

debug

the perl on his system.  I got no reply!  The error would appear
to be from Rcmd massage-Examples.sh.

Argh! Sorry. But the strategy persists: Try doing the relevant steps
manually and get more clues, either in the form of error messages or
in pinpointing which spot in the input files triggers the error.

A "set -x" inserted near the beginning of the massage-Examples script
might be helpful (um, this is Bash, right?).

Thanks to Prof. Dalgaard and Prof. Ripley. Honestly, I'm new to Perl
so I couldn't check the script file to locate the problem. However,
I just managed to get an introductory book on Perl, I'll see what
I can learn from it.


Thanks a lot,
