NAME
- Mac OS X 10.7.4 Update has been released by Apple, the update includes bug fixes and security updates and is recommended for all OS X Lion users to install. Two of the most significant changes are a fix to a restoring windows bug and a patch for a potential security.
- I installed perl 5.16.0, threaded, on Mac OS X 10.7.5, using perlbrew. Now, when I try to transfer modules to the new install, it fails with a message that I don't understand. Below are commands I used and output. $ perlbrew install -as perl-5.16.0t -Dusethreads perl-5.16.0 Then, following a post on perlmonks.
Perl editor and IDE for macOS / Mac OS X, Windows, and Linux features such as syntax highlighting, the Perl code builder, the Perl code assistant, and the Perl function list tool.
perlmacosx - Perl under Mac OS X
SYNOPSIS
This document briefly describes Perl under Mac OS X.
DESCRIPTION
The latest Perl release (5.32.0 as of this writing) builds without changesunder all versions of Mac OS X from 10.3 'Panther' onwards. Smart notebook for mac os x 10.10.
In order to build your own version of Perl you will need 'make',which is part of Apple's developer tools - also known as Xcode. FromMac OS X 10.7 'Lion' onwards, it can be downloaded separately as the'Command Line Tools' bundle directly from https://developer.apple.com/downloads/(you will need a free account to log in), or as a part of the Xcode suite,freely available at the App Store. Xcode is a pretty big app, sounless you already have it or really want it, you are advised to get the'Command Line Tools' bundle separately from the link above. If you wantto do it from within Xcode, go to Xcode -> Preferences -> Downloads andselect the 'Command Line Tools' option.
Between Mac OS X 10.3 'Panther' and 10.6 'Snow Leopard', the 'CommandLine Tools' bundle was called 'unix tools', and was usually suppliedwith Mac OS install DVDs.
Earlier Mac OS X releases (10.2 'Jaguar' and older) did not include acompletely thread-safe libc, so threading is not fully supported. Also,earlier releases included a buggy libdb, so some of the DB_File testsare known to fail on those releases.
Installation Prefix
The default installation location for this release uses the traditionalUNIX directory layout under /usr/local. This is the recommended locationfor most users, and will leave the Apple-supplied Perl and its modulesundisturbed.
Using an installation prefix of '/usr' will result in a directory layoutthat mirrors that of Apple's default Perl, with core modules stored in'/System/Library/Perl/${version}', CPAN modules stored in'/Library/Perl/${version}', and the addition of'/Network/Library/Perl/${version}' to @INC for modules that are storedon a file server and used by many Macs.
SDK support
First, export the path to the SDK into the build environment:
Please make sure the SDK version (i.e. the numbers right before '.sdk')matches your system's (in this case, Mac OS X 10.8 'Mountain Lion'), as it ispossible to have more than one SDK installed. Also make sure the path existsin your system, and if it doesn't please make sure the SDK is properlyinstalled, as it should come with the 'Command Line Tools' bundle mentionedabove. Finally, if you have an older Mac OS X (10.6 'Snow Leopard' and below)running Xcode 4.2 or lower, the SDK path might be something like
'/Developer/SDKs/MacOSX10.3.9.sdk'
.You can use the SDK by exporting some additions to Perl's 'ccflags' and '.flags'config variables:
Universal Binary support
Note: From Mac OS X 10.6 'Snow Leopard' onwards, Apple only supportsIntel-based hardware. This means you can safely skip this section unlessyou have an older Apple computer running on ppc or wish to create a perlbinary with backwards compatibility.
You can compile perl as a universal binary (built for both ppc and intel).In Mac OS X 10.4 'Tiger', you must export the 'u' variant of the SDK:
Mac OS X 10.5 'Leopard' and above do not require the 'u' variant.
In addition to the compiler flags used to select the SDK, also add the flagsfor creating a universal binary:
Keep in mind that these compiler and linker settings will also be used whenbuilding CPAN modules. For XS modules to be compiled as a universal binary, anylibraries it links to must also be universal binaries. The system libraries thatApple includes with the 10.4u SDK are all universal, but user-installed librariesmay need to be re-installed as universal binaries.
64-bit PPC support
Follow the instructions in INSTALL to build perl with support for 64-bit integers (
use64bitint
) or both 64-bit integers and 64-bit addressing(use64bitall
). In the latter case, the resulting binary will run onlyon G5-based hosts.Support for 64-bit addressing is experimental: some aspects of Perl may beomitted or buggy. Note the messages output by Configure for further information. Please use https://github.com/Perl/perl5/issues to submit aproblem report in the event that you encounter difficulties.
When building 64-bit modules, it is your responsibility to ensure that linkedexternal libraries and frameworks provide 64-bit support: if they do not,module building may appear to succeed, but attempts to use the module willresult in run-time dynamic linking errors, and subsequent test failures.You can use
file
to discover the architectures supported by a library:Note that this issue precludes the building of many Macintosh-specific CPANmodules (
Mac::*
), as the required Apple frameworks do not provide PPC64support. Similarly, downloads from Fink or Darwinports are unlikely to provide64-bit support; the libraries must be rebuilt from source with the appropriatecompiler and linker flags. For further information, see Apple's64-Bit Transition Guide athttps://developer.apple.com/library/archive/documentation/Darwin/Conceptual/64bitPorting/transition/transition.html.libperl and Prebinding
Mac OS X ships with a dynamically-loaded libperl, but the default forthis release is to compile a static libperl. The reason for this ispre-binding. Dynamic libraries can be pre-bound to a specific address inmemory in order to decrease load time. To do this, one needs to be awareof the location and size of all previously-loaded libraries. Applecollects this information as part of their overall OS build process, andthus has easy access to it when building Perl, but ordinary users wouldneed to go to a great deal of effort to obtain the information neededfor pre-binding.
You can override the default and build a shared libperl if you wish(Configure .. -Duseshrplib).
With Mac OS X 10.4 'Tiger' and newer, there is almost no performancepenalty for non-prebound libraries. Earlier releases will suffer a greaterload time than either the static library, or Apple's pre-bound dynamic library.
Updating Apple's Perl
In a word - don't, at least not without a *very* good reason. Your scriptscan just as easily begin with '#!/usr/local/bin/perl' as with'#!/usr/bin/perl'. Scripts supplied by Apple and other third parties aspart of installation packages and such have generally only been testedwith the /usr/bin/perl that's installed by Apple.
If you find that you do need to update the system Perl, one issue worthkeeping in mind is the question of static vs. dynamic libraries. If youupgrade using the default static libperl, you will find that the dynamiclibperl supplied by Apple will not be deleted. If both libraries arepresent when an application that links against libperl is built, ld willlink against the dynamic library by default. So, if you need to replaceApple's dynamic libperl with a static libperl, you need to be sure todelete the older dynamic library after you've installed the update.
Known problems
If you have installed extra libraries such as GDBM through Fink(in other words, you have libraries under /sw/lib), or libdlcompatto /usr/local/lib, you may need to be extra careful when runningConfigure to not to confuse Configure and Perl about which librariesto use. Being confused will show up for example as 'dyld' errors aboutsymbol problems, for example during 'make test'. The safest bet is to runConfigure as
to make Configure look only into the system libraries. If you have someextra library directories that you really want to use (such as newerBerkeley DB libraries in pre-Panther systems), add those to the libpth:
The default of building Perl statically may cause problems with complexapplications like Tk: in that case consider building shared Perl
but remember that there's a startup cost to pay in that case (see above'libperl and Prebinding').
Starting with Tiger (Mac OS X 10.4), Apple shipped broken locale files forthe eu_ES locale (Basque-Spain). In previous releases of Perl, this resulted infailures in the lib/locale test. These failures have been suppressedin the current release of Perl by making the test ignore the broken locale.If you need to use the eu_ES locale, you should contact Apple support.
Cocoa
There are two ways to use Cocoa from Perl. Apple's PerlObjCBridgemodule, included with Mac OS X, can be used by standalone scripts toaccess Foundation (i.e. non-GUI) classes and objects. Guest additions virtualbox for mac os x.
An alternative is CamelBones, a framework that allows access to bothFoundation and AppKit classes and objects, so that full GUI applicationscan be built in Perl. CamelBones can be found on SourceForge, athttps://www.sourceforge.net/projects/camelbones/.
Starting From Scratch
Unfortunately it is not that difficult somehow manage to break one'sMac OS X Perl rather severely. If all else fails and you want toreally, REALLY, start from scratch and remove even your Apple Perlinstallation (which has become corrupted somehow), the followinginstructions should do it. Please think twice before followingthese instructions: they are much like conducting brain surgery toyourself. Without anesthesia. We will not come to fix your systemif you do this.
First, get rid of the libperl.dylib:
Then delete every .bundle file found anywhere in the folders:
Nmap for mac os x lion download iso. You can find them for example by
After this you can either copy Perl from your operating system media(you will need at least the /System/Library/Perl and /usr/bin/perl),or rebuild Perl from the source code with
Configure -Dprefix=/usr-Duseshrplib
NOTE: the -Dprefix=/usr
to replace the system Perlworks much better with Perl 5.8.1 and later, in Perl 5.8.0 thesettings were not quite right.Perl For Mac Os X 10.7 10 7 Download
'Pacifist' from CharlesSoft (https://www.charlessoft.com/) is a niceway to extract the Perl binaries from the OS media, without having toreinstall the entire OS.
