Hi All,

Help!

I just upgraded Fedora from 30 to 31.

I upgraded to rakudo-pkg-Fedora31-2019.07.1-03.x86_64.rpm
from https://github.com/nxadm/rakudo-pkg/releases

Now P6 can not find my subs inside my modules:

# perl6 -I/home/linuxutil/p6lib -MPrintColors -e 'PrintGreen( "Hi\n" );'
     ===SORRY!=== Error while compiling -e
     Undeclared name:

The stock "rakudo" and "rakudo-zef" that resides in the
Fedora repo's has the same issue.

Many thanks,

Follow up:

Fedora 31 became hard nosed about my mistakes.  Tom
called it.

I had thought all my modules used "unit module MyModule;", but
into everyone life a little humility must fall, not all of them were. 
They are now.


And everyone that imported things suddenly demanded I
use :some-key nicknames, which makes my code a lot
easier to maintain.

Everything is behaving now.  Thank you!

Lets hope my modules still like the position of the moon
when it goes down!

Yes. The "shebang" line

I had to use find to located it.  Then I created links.

# ls -s /opt/rakudo-pkg/bin/zef   /usr/bin/zef
# ls -s /opt/rakudo-pkg/bin/perl6 /usr/bin/perl6

Then which found it.

Hi Tom,

This computer is a mock up of their configuration.  It does

I have two customer's server waiting for this one to
pass muster.  And I will run it for at leat a month

So far, I have figured out the changes in dhcpd, the
new ports used by bind (SPT and DPT are no longer
identical), unbuggered bind-chroot, SELinux
and named conflict, qemu and version rising,
and "dnf system-upgrade" issues.

Perl 6 is the last item on the list.  I hope.

Life in the fast lane!

# perl6 -I./p6lib -e 'use ModuleTest :ModuleTest, :ModuleTst;
ModuleTest; ModuleTst; # correct'

it should look like in the first line, the comma right between

One thing I noticed, you are missing a line at the top of your modules 
that should read something like "unit module MyModule;", 


My actual modules all have this

and the 
export(:some-key) is okay.


But then, in the calling programs, use them something like this:

use lib ;     # MyModule.pm6 is in this dir
use MyModule :some-key1, :some-key2; # note comma


This is my favorite method as it is far easier to maintain

selinux operates at a higher level. This is plain and simple not having 
the write bit set for your particular user.


Anyway, try this (as a regular user)

* Create a META6.json metadata file for every module, or a bunch of 
them, using the classic module layout (in a lib/ directory from root).

That is

/-- META6.json
     lib/
    MyModule.pm6

Make sure that MyModule.p6 is actually declared that way.
* zef test . (always a good idea too, including writing those self same 
tests)

* zef install . (zef will run tests too, so you double check).

That's the advised way to proceed always when you're developing a 
module. Once installed, you can use your modules from anywhere and, 
since they are in the default location, no need to use lib or -I.


BTW, that's clearly specified in the official documentation for modules 
https://docs.raku.org/language/modules

Hi JJ,

Not seeing the point, especially since I DO NOT want other
to see my code when I migrate it to my various customer's servers.  I 
also do not want others to see my code on this (LUKS encrypted) computer 
either.  On my customer's

servers, all my code  and directories are hidden to
everyone but root.  (The owner of the company gets a
list all users and passwords, as it is his property,
not mine.)

And everything I have installed with zef is working so far.

What write bit?  User root and group users can write
just fine to that directory.

# ls -al p6lib
total 84
drwxrwxr-x.  4 tony users  4096 Nov  3 23:12 .

They even can create a .precomp:


With this, everyone can write to it (I set it back afterwards)

[root@rn6 linuxutil]# chmod 2777 p6lib
[root@rn6 linuxutil]# perl6 -I/home/linuxutil/p6lib -e 'use ModuleTest; 
ModuleTest; ModuleTst;'
===SORRY!=== Error while compiling /home/linuxutil/p6lib/ModuleTest.pm6 
(ModuleTest)

Undeclared name:
ModuleTest used at line 4

This is a read issue.  P6 can read the file, but can
not process the subs correctly.

And it is not a Perl6 issue either.  The exact perl
(rakudo-pkg-Fedora30-2019.07.1-03.x86_64.rpm) I ran
on Fedora 30 has the same issue under Fedora 31.

What did Fedora 31 do?   AHH!!

One thing I noticed, you are missing a line at the top of your modules that
should read something like "unit module MyModule;", and the
export(:some-key) is okay.

But then, in the calling programs, use them something like this:

use lib ; # MyModule.pm6 is in this dir
use MyModule :some-key1, :some-key2; # note comma

HTH,

selinux operates at a higher level. This is plain and simple not having the
write bit set for your particular user.

Anyway, try this (as a regular user)

* Create a META6.json metadata file for every module, or a bunch of them,
using the classic module layout (in a lib/ directory from root).
That is

/-- META6.json
lib/
   MyModule.pm6

Make sure that MyModule.p6 is actually declared that way.
* zef test . (always a good idea too, including writing those self same
tests)
* zef install . (zef will run tests too, so you double check).

That's the advised way to proceed always when you're developing a module.
Once installed, you can use your modules from anywhere and, since they are
in the default location, no need to use lib or -I.

BTW, that's clearly specified in the official documentation for modules
https://docs.raku.org/language/modules

You don't have to _develop_ them as root, though. Development, and
everything related to it, up to and including the version of the language
you're using, should never be done with root privileges.

I've seen this message as well. I believe it's the default message you

Maybe try 'echo $PATH' at a terminal prompt, and see if your new

HTH, Bill.




As long as it is "normal".

Thank you!
