how to "re-enable" perl after 5.32 install; how to reinstall all perl-mods?

how to "re-enable" perl after 5.32 install; how to reinstall all perl-mods?

[L A Walsh]

This is getting really icky...

updated cygwin and it reinstalled a new version of perl,
but when I try to run any perl progs nothing runs (see below).

So I'd like to try to reinstall all the cygwin
perl-mods that I have installed.

How can I select "all" among the perl mods? and install?

I can select for only the "installed" perl mods, but how can
I tell it to reinstall all of them?

According to /etc/setup, there are about 202 modules that need
to be reinstalled, but I don't see howto tell setup to re-install
all the "installed" modules (so I can be sure they are all "refreshed".

Thanks

(errors from 2 of my local perl progs, "pcalc" and "dedup")
and trying cpan....which also doesn't work. :-(

You didn't say how you updated Cygwin, but if you used setup then it
already did exactly that.

I'm not sure I understand your question, but how would you re-install a
not installed module?

Again, they already should be.

Well, I'm afraid I can't help you with an error so non-specific.

None of the stuff in /usr/local/ comes from Cygwin, that was all put
there by yourself.  How about you move that away first?

So your ExtUtils::MakeMaker installation seems incomplete, you need to
install the perl-ExtUtils-MakeMaker package at least.

Thanks, mostly.  It did try to install them, but the solver was/is
too smart, it comes up with 2 solutions 1/2 to uninstall 5.32,
install 5.30-x  and a bunch of other modules, and
(2/2) (Default) Don't uninstall 5.30 and keep 5.32.

I think the db-base in /etc/setup contains all the 5.32
compat modules -- so it basically saw all those uninstalls/reinstall
and just told me it was taking the easier path! ;-)

How does one pick a non-default choice at that point (not that
this was the only problem -- seems I have existing modules
installed in 5.32 under a local site_lib directory.
Problem there is that the existing modules there don't link:
HiRes.c: loadable library and perl binaries are mismatched (got 
handshake key 0x
800000770, needed 0x0)

But if i just push that dir out of the way, the 1st prog
I tried (pcalc that led to me trying cpan which didn't
work) now works, however the 2nd prog "dedup", wouldn't
work because of a missing prereq from CPAN which won't make:
>  dedup
Can't locate POSIX/RT/Semaphore.pm in @INC (you may need to install the 
POSIX::RT::Semaphore module)

Tried making that, but I don't think it is compatible
with 5.32 due to incompatible changes in perl (vaguely remember
something like that, but not sure...)

But it fails with:

Trying to use the old 5.32 tree a fall back for anything
that fell to relying on /usr/local/lib/perl5/site_perl/5.32, I get the

mistmatched nonsense..(damn**)
HiRes.c: loadable library and perl binaries are mismatched (got 
handshake key 0x800000770, needed 0x0)

**-now perl libs are checking for version mismatches at dl-load time?
ARG! - it seems it used to work before this update, but is this
a new 5.32 update?  Got handshake key 0x800000770, needed 0x0? what
does that hex code mean? or what version was/is it looking for?

Sigh...where are the flags to 'setup' documented?

Last time I tried  setup.exe -h, it just hopped into the standard
download dialogues...

Thanks! ;^) (sigh)

    Why would it have reinstalled all of the modules it just
installed?

    I need to _RE_-install (to make sure all of the existing
modules correspond to what was downloaded by the 5.32 update.

I have possible doubts as to their integrity.

    I wanted to re-install all of the **installed** modules to verify

Yeah, I had a bunch of modules in the previous 5.30 tree from
'site' that didn't get remade and I didn't know perl 5.32
was going to cause so many problems that I couldn't run most
of the stuff I had.

On linux I had backups in the worst case and could restore
a perl dir to capture all the modules I would need to recompile
from cpan, but on windows, don't have a good backup program since
MS removed MSbackup in Win7, so people couldn't backup binary
programs (except via image restores).  Grr.

I think that the problem I have in Cygwin-setup is it is
difficult to 'keep' an older binary install from something like perl
as one has to go through and 'keep' every compat module that
is installed for perl along the way every time you run setup.

Cygwin really needs to use something like rpm for POSIX-compatible
package management and only use setup for the cygwin-binaries
that need to be installed outside of
setup.

Then cygwin could use all the package management utils
from linux (RH, Suse, et al.) that would allow more flexible
local package management.

Rt. now have to figure out how to make POSIX::RT::Semaphore
work in new perl...only emphasizing why perl is falling out of
favor as a devel. env.  *sigh*...
