Upgrade Perl 5.40 to 5.42: /usr/local/include/crypt.h:73:8: error: redefinition of 'crypt_data'

SevenDayz · Nov 20, 2025

Hello everyone!

I tried to upgrade Perl 5.40 to 5.42, and I got an error "redefinition of 'crypt_data'".

The full build log and my /etc/make.conf are attached.

I ran:
portmaster -o lang/perl5.42 lang/perl5.40

The error:

"crypt.h" seems to origin from security/libxcrypt. Try to upgrade that port first.

A test run (in a VM) of ports-mgmt/portmaster upgrade of perl5.40 to perl5.42 (with only build dependencies devel/ccache and ports-mgmt/pkg installed) doesn't produce any errors, installation completes normally.

libxcrypt seems to depend on lang/perl5.42:

Code:

ports/security/libxcrypt % make all-depends-list | grep perl5
/usr/ports/lang/perl5.42

Perhaps force delete libxcrypt, upgrade to perl5.42, install libxcrypt.

I had no luck.

What do you mean? User pkg delete?
Well, I'd tried it:

Code:

pkg delete security/libxcrypt

Code:

Updating database digests format: 100%

Code:

Checking integrity... done (0 conflicting)

Code:

Deinstallation has been requested for the following 449 packages (of 0 packages in the universe):

Deleting 449 packages is too much for me.
It isn't impossible, but ....

Maybe I should have described it more precisely how to proceed.

T-Daemon said:

Code:

pkg del -f libxcrypt

or

Code:

ports/security/libxcrypt # make deinstall

This will remove only libxcrypt, not the packages depending on it.

Mind you, you're going to have to rebuild everything that depends on libxcrypt too, or else your dependency chain will be wrecked.

Exactly.

Ideally ports-mgmt/portmaster should be run to update all ports all at once, not just one port at a time.

portmaster(8)

Code:

EXAMPLES

     Update all ports that need updating:
           portmaster -a

If I uncomment the "DEFAULT_VERSIONS+= perl5=5.42" line, I get the same (or very similar) error.
If I comment out the "DEFAULT_VERSIONS+= perl5=5.42" line, it builds smoothly.

Well, the command
portmaster -d --no-confirm -x dom4j -a
failed with the same error.

Code:

DEFAULT_VERSIONS+= perl5=5.42

By the way, lists of updated and not-updated ports looks very incomplete.

It's solved the problem! Thank you very much!

SevenDayz a general recommendation is to *not* mess with your system perl. Leave that to the system to manage. The reason is, if you "break" your system perl somehow, your system might get affected when it attempts to run a broken perl.

You should instead install a different perl for your user. You can do that very easily with with "perl version manager", for example:

perlbrew: https://perlbrew.pl/ (https://metacpan.org/pod/App::perlbrew).

or, local::lib: https://metacpan.org/pod/local::lib

There are others too, like "plenv" but perlbrew or local::lib should do.

Plus you dont need root to install them and to install modules for them.

To install modules, use "cpanm" : https://metacpan.org/pod/App::cpanminus#Installing-to-local-perl-(perlbrew,-plenv-etc.)

Do you mean I should comment the line "DEFAULT_VERSIONS+= perl5=5.42"?

Yes, you should remove "DEFAULT_VERSIONS+= perl5=5.42".

The default versions are set in the ports framework globally in /usr/ports/Mk/bsd.default-versions.mk

Rich (BB code):

# Possible values: 5.38, 5.40, 5.42, devel
.  if !exists(${LOCALBASE}/bin/perl) || (!defined(_PORTS_ENV_CHECK) && \
    defined(PACKAGE_BUILDING))
# When changing the default here, make sure the DEPRECATED/EXPIRATION lines in
# the older Perl 5 ports are uncommented at the same time.
PERL5_DEFAULT?=         5.42

Unless you want to override default versions, don't specify default versions which are already default.

The upgrade procedure for perl5 using ports-mgmt/portmaster described in /usr/ports/UPDATING does also advice the removal.

Rich (BB code):

20231017:
  AFFECTS: users of lang/perl5*
  AUTHOR: delphij@FreeBSD.org
 
  ...
    First, add to /etc/make.conf:

  DEFAULT_VERSIONS+=  perl5=5.36
 
  ...
    Portmaster users:
        portmaster -o lang/perl5.36 lang/perl5.34

          You can now remove the DEFAULT_VERSIONS line added earlier
          from /etc/make.conf
