It would be awesome if Perlbrew could auto-configure CPAN.pm when it builds a new perl, including setting urllist, and have it put all its build jibber-jabber in a perl-build-specific directory such as .../perl-$VERSION/.cpan

A useful feature would be the ability to clone previously brewed perls, saving on the amount of time it takes to recompile and rebuild all of perl, and also ensuring that module versions are automatically consistent between installations. This would probably require some fairly clever hacks in terms of altering the compiled-in search path (binary patching?), but if it could be made to work, it would be pretty awesome.

Saw the announcement about Ubuntu 11.04 and upgraded Perlbrew to 0.21 and Devel::PatchPerl to 0.36, but I still can't install perl-5.12.3 because patchperl fails to find Devel::PatchPerl in PERL5LIB, because Perlbrew.pm deletes it right before it calls patchperl (in do_install_this()).

My modules are in a local::lib and that's the only way I can install D::PatchPerl on some machines. Not sure how to work around this. I assume PB wants to avoid pollution from PERL5LIB, but how else am I supposed to find D::PatchPerl?

the patchperl downloaded from
https://gist.github.com/raw/962406/eeffe0e4acf0cc6ff1fa7bc60586d3dc26e3f41a/patchperl

has a shebang line of

!/usr/bin/env patchperl

That looks odd to me, but i'll take your word for it if its supposed to be that way.

I looked at the fatpacked version of cpanm and it in fact uses the more normal looking

!/usr/bin/env perl

Just thought I'd let you know in case that was incorrect.

p.s. I tried to fork and edit the gist (https://gist.github.com/962861) but couldn't figure out how to do a pull request from there.

I want to install 5.14.0-RC2 from a particular URL, it'd be great if:

Hi there,

I love perlbrew!

However, when compiling a bunch of perls I like to use ccache to speed things up. However, it looks like the -Dcc=ccache\ gcc is turned into -Dcc=ccache, which does not compile things properly:

Checking compatibility between /bin/echo and builtin echo (if any)...
They are not compatible!  You are probably running ksh on a non-USG system.
I'll have to use /bin/echo instead of the builtin, since Bourne shell doesn't
have echo built in and we may have to run some Bourne shell scripts.  That
means I'll have to use '-n' to suppress newlines now.  Life is ridiculous.

Part of the installation for perlbrew is setting config information for CPAN... What is this used for? I see that cpanm is installed in a perlbrew directory. Where do modules installed by this cpanm get installed, just for the currently selected perl?

Thanks.

@briandfoy said:

I don't like how CPAN.pm uses the same configuration file for any
invocation no matter the perl or cpan I'm using (e.g. cpan5.12.2
cpan5.14.0 and so on), but I haven't really done anything to fix that.

However, a short term fix might involve you using the -j switch to cpan
to load any config file that you like instead of the one CPAN.pm wants
to use. It's a hack, but that's what there is right now.

Using perlbrew is probably the most common reason to have multiple perls; can we do something to alleviate this headache?

If I install a Perl environment with perlbrew under a certain name, and I already have a Perl environment under that name, perlbrew will overwrite it without a second thought. To reproduce:

$ perlbrew install --as test-instance perl-5.14.0
$ perlbrew install --as test-instance perl-5.8.9

I think perlbrew should die with a message of something like "You already have test-instance installed".

Devel::PatchPerl was just updated to fix an issue causing test failures on perl 5.14 (and likely some versions of 5.13).

Here is the closed issue:
bingos/devel-patchperl#3 (comment)

The change was small enough that I simply edited my own ~/perl5/perlbrew/bin/patchperl
but please update the patchperl that perlbrew uses.

Thanks!

*** SEE ISSUE #26 WITH PROPOSED PATCH ***

It seems that GitHub switched to an SSL-only interface, redirecting plain HTTP requests to their HTTPS counterparts. This makes perlbrew fail when downloading cpanm, because HTTP::Lite does not support SSL.

I would personally leave the installation of cpanm out of perlbrew, but that's me.

Cheers,

Flavio.

Lies!!

The provided cshrc doesn't source ~/.perlbrew/init, so $PERLBREW_ROOT is never populated.

Like it says on the tin - this needs to be documented.

Minor typo. :-) Is the source for the website available somewhere?

To provide better interactive / non-interactive use perl installations, there are should be some easy usages for people to run programs with specified perl without a switch/use beforehand.

Suppose a perlbrew root with the following installations:

> perlbrew list
  perl-5.10.1
  perl-5.12.3
* perl-5.14.0
  perl-5.8.9
  /usr/bin/perl (5.10.0)

Then perlbrew should take an additional selector argument before exec, to specify the installation names. For example:

# run myprogram.pl with perl-5.12.3
perlbrew perl-5.12.3 exec  myprogram.pl

# run myprogram.pl with perl-5.12.3 and perl-5.14.0
perlbrew perl-5.12.3,perl-5.14.0 exec  myprogram.pl

# run myprogram.pl with all perls
perlbrew exec  myprogram.pl

# die with error, because perl-5.10.0 is not installed here
perlbrew perl-5.10.0 exec  myprogram.pl

# die with error, also because perl-5.10.0 is not installed here
perlbrew perl-5.12.3,perl-5.10.0 exec  myprogram.pl

The content of selector should be a comma-separated list of installation names, without spaces in between.

If any one or more of the specified installations cannot be found, then perlbrew must die with error messages specifying the missing ones, without executing the command at all.

When a version doesn't exist, perlbrew doesn't die properly:

Strawberry Perl has gcc built-in. I noticed that perlbrew fails to even 'perlbrew init'. It would be cool that i can have perlbrew on win32?

I did a clean install of perlbrew 0.12 and found the following issues.

If one attempts to use perlbrew 0.12 within a bash script, it falls back to its old behavior of creating links in $PERLBREW_ROOT/bin (Issue 1). These links get used instead of the intended version of Perl in the path because perlbrew falls first in the path (Issue 2).

using "make test_harness" means the "-j" options from HARNESS_OPTIONS will be used.

Support for it was added in 1167a30e646ca68516b6d6fe00c979246aa8df3a in perl.git, so it's OK for perl-5.7.3 or later.

When you use -U, it actually runs it under -D as well.

When I ran:
perlbrew install perl-5.13.3 -U something
it actually ran:
[...]
Configure [...] -D-Usomething [...]

On line 1430, the POD has a duplicate -?| --help where I think you want --version. (Note that it can't be -v| --version since -v is taken already for the verbose option.)

=item B<-?| --help>

prints this help.

=item B<-?| --help>

prints the version of App::perlbrew.

Details:
I was previously using an older version of perlbrew and had a helper script that would call 'perlbrew switch' and 'hash -r'. When I upgraded to perlbrew version 0.12, I noticed that it wasn't working any more. I looked at the code and noticed that perlbrew used a bash wrapper that should run 'hash -r' for me now. Thinking that the changes to perlbrew were preventing my script from functioning, I tried just running 'perlbrew switch' and found that it wasn't updating the links.

Summary:
When you run 'perlbrew switch', the bash wrapper that gets used does not update the links. This results in perlbrew showing that it has switched versions of Perl when it has not.

The workaround is to run 'env perlbrew switch' instead.

There's no documentation in stalled for man perlbrew - the same documentation available via perlbrew --help or perldoc perlbrew should be in man perlbrew.

Pull request #77 has done some of this work.

Maybe the "perl-" prefix can be omitted in general when used in command line.

If network connectivity isn't available or an exception is encountered, perlbrew steams on ahead.

• perlbrew available prints nothing; I think it should at least say "unable to retrieve list of perls"
• perlbrew install perl-5.14.0 (or some other release) complains and exits, which is ok; but if the relevant tarball is found under dists/, it still fails; I think it should fallback to building the existing distribution.
• perlbrew mirror complains that you haven't selected a mirror. I think a better error message should be presented.
• perlbrew install perl-blead results in an error message from tar.
• perlbrew install-cpanm blows away the existing cpanm, and replaces it with an empty file.

To reproduce and test for these issues, add the following to your /etc/hosts:

127.0.0.1 perl5.git.perl.org www.cpan.org search.cpan.org github.com

After that, just run the commands I mentioned above.

Hi,

I've just installed perlbrew on my Mac OS X 10.5 where I have previously installed perl 5.10.1 (in /usr/local/) along with the default perl 5.8.8 (in /usr/bin). When I try to install perl 5.12 (or 5.13, the only two I've tried) it fails with the output below. I'd rather not force install and if I do I'm not sure it would even work. Any ideas?

Thank you.

I think that perlbrew env should also show the value of PERLBREW_PERL-- i.e. it should show all environment variables set by perlbrew.

Why not run 'perlbrew init' automagically the first time the user tries to do anything perlbrew-ish, instead of having it as an extra manual step.

Sorry for my poor english.

perlbrew -f switch <dist> or perl perlbrew switch <dist> make symbolic links. It cause a problem of using a env command. So a switch command doesn't work.

The switch command now use a global symlink inside $PERLBREW_ROOT to keep tracking current activated perl. The problem with this approach is that it is not friendly when multiple users are sharing the same PERLBREW_ROOT.

To solve this, perlbrew switch should be re-written completely in bash, it should save the result in ~/.perlbrew/init, which is a personal directory.

There are several RT issues related to switch, that should be taken care of after the rewrite:

Devel::PatchPerl was updated.
Please regen patchperl :)

My use case for perlbrew is that for almost everything I'm replacing the system perl on my server with a perlbrew maintained installation.

I install modules & perlbrew versions under the user v-perlbrew hosted in /home/v-perlbrew, but other users (e.g. cronjobs etc) use that perl.

It used to be that I could just add something like this to my cronjobs:

PATH=/home/v-perlbrew/perl5/perlbrew/bin:/home/v-perlbrew/perl5/perlbrew/perls/current/bin:/bin:/usr/bin

But now that perlbrew seems to no longer create the /home/v-perlbrew/perl5/perlbrew/bin symlink I have to now maintain it myself, e.g.:

sudo rm -rfv /home/v-perlbrew/perl5/perlbrew/bin
sudo ln -sf /home/v-perlbrew/perl5/perlbrew/perls/perl-5.14.0/bin /home/v-perlbrew/perl5/perlbrew/bin

And furthermore, users that are not cronjobs had to have this in their .bashrc:

test -f ~v-perlbrew/perl5/perlbrew/etc/bashrc && source ~v-perlbrew/perl5/perlbrew/etc/bashrc

Changed to:

test -f ~v-perlbrew/perl5/perlbrew/etc/bashrc && HOME=/home/v-perlbrew source ~v-perlbrew/perl5/perlbrew/etc/bashrc

Since the ~/perl5/perlbrew/etc/bashrc now makes the assumption (which it didn't before) that ~/perl5 can be found under $HOME, as opposed to having the full paths hardcoded in.

Proposed fixes to make this workflow work:

• Instead of looking under $HOME look under a path relative to the bashrc being sourced
• Provide an option to maintain the "bin" symlink again, or put it back in by default.

Thanks.

I think this will help many people over proxy servers.
$ua->proxy($ENV{http_proxy}) if $ENV{http_proxy};

I think perlbrew's usefulness would be further enhanced by a configuration file; one could even leverage the existing Conf.pm that is used for mirror selection. This could come in handy if I want to make sure all the perl environments I install have a certain set of compilation flags; for example -Doptimize=-O2 -Dman1dir=' ' -Dman3dir=' '. I know I could accomplish this with shell aliasing, but then I'd lose those settings if I ran perlbrew from within a script.

Also, I think that the settings for a build could be organized into profiles; that way, I could have a default profile with the example settings from above, and a debug profile with debugging enabled in the interpreter and using Perl's malloc for Devel::Peek::mstat. If I wanted to install a Perl interpreter for version 5.8.9 for debugging, I could simply do this:

perlbrew install --profile debugging perl-5.8.9 --as perl-5.8.9-debug

Thoughts?

After a perl's test suite fails, instead of making the user re-build the perl, re-run the tests and then force installation, we should offer a prompt that explains that the user should review the log, and decide whether they want to force installation right now.

Hi,

I am unable to fix it from past 3 days and I desperately need someone to help me on this. I installed perlbrew like a charm on Ubuntu 10.10 and it worked great. But now I upgraded to 11.04 and am finding issues. I know that the issue is with GCC linker options -lm (linking math.h) and -lrt (time.h). Here are the errors. Can some one tell me how I can fix this problem ?

Hi,

Github switched to HTTPS only and Perlbrew uses HTTP::Lite to fetch cpanm at some point. The following warning is printed now:

Only http is supported by HTTP::Lite at /home/melo/perl5/perlbrew/bin/perlbrew line 149.
Fail to get https://github.com/miyagawa/cpanminus/raw/master/cpanm (error: ) at /home/melo/perl5/perlbrew/bin/perlbrew line 1433.

I can't quite put it, but basically I tried to install perl-5.6.2 for testing, and got bitten by this: http://www.gossamer-threads.com/lists/perl/porters/225634

I apparently just need to patch makefile, but is there a way to do this with perlbrew?
