| 3 | +------------- |
| 4 | + |
| 5 | +Summary of user-visible Configure and build changes since 5.001: |
| 6 | + |
| 7 | +Yet more enhancements and fixes have been made to the Configure and |
| 8 | +build process for perl. Most of these will not be visible to the |
| 9 | +ordinary user--they just make the process more robust and likely to |
| 10 | +work on a wider range of platforms. |
| 11 | + |
| 12 | +This is a brief summary of the most important changes: |
| 13 | + |
| 14 | + Include 5.000 - 5.001 upgrage notes :-) (see below). You might |
| 15 | + want to read through them as well as these notes. |
| 16 | + |
| 17 | + Install documentation for perl modules and pod2* translators. You can |
| 18 | + now view perl module documentation with either your system's man(1) |
| 19 | + program or with the supplied perldoc script. |
| 20 | + |
| 21 | + Support Linux ELF dynamic loading. |
| 22 | + |
| 23 | + Many hint file updates. |

| 27 | +Version 5.001 |
| 28 | +------------- |
| 29 | + |
| 30 | +Summary of user-visible Configure and build changes since 5.000: |
| 31 | + |
| 32 | +A large number of enhancements and fixes have been made to the |
| 33 | +Configure and build process for perl. Most of these will not be |
| 34 | +visible to the ordinary user--they just make the process more robust |
| 35 | +and likely to work on a wider range of platforms. |
| 36 | + |
| 37 | +This is a brief summary of the most important changes. |
| 38 | + |
| 39 | +Configure changes: |
| 40 | + New and improved Configure command line options. -O now overrides |
| 41 | + config.sh settings. -D options can now include spaces, if |
| 42 | + protected in quotes (e.g. -Dcc='gcc -posix'). Type Configure -h |
| 43 | + for a full listing of options. |
| 44 | + |
| 45 | + Users can now turn on the defaults for the rest of Configure by |
| 46 | + typing &-d at any Configure prompt. This is useful if you just |
| 47 | + want to change one or two answers. |
| 48 | + |
| 49 | + Support on (non-Sun) SVR4 systems for dynamic loading and shared |
| 50 | + libperl.so |
| 51 | + |
| 52 | + Numerous new or updated hints files: PowerUnix, aix 3.x and 4.x, |
| 53 | + bsd386, convexos, cxux, DEC OSF, Esix, FreeBSD, HP-UX (especially if |
| 54 | + you're using the bundled compiler), irix 4.x, 5.x, and 6.x, Linux, |
| 55 | + MPE/IX, NeXT 3.0 and 3.2, Solaris, SVR4, Ultrix (especially 4.3), |
| 56 | + and Unicos. |
| 57 | + |
| 58 | + Improved generation of a suitable name for architecture-dependent |
| 59 | + library files. NOTE: This may differ from the name you had from |
| 60 | + your 5.000 installation. |
| 61 | + |
| 62 | + Many many portability enhancements and fixes. |
| 63 | + |
| 64 | +Build process: |
| 65 | + |
| 66 | + The process for building extensions has been extensively revised. See |
| 67 | + lib/ExtUtils/MakeMaker.pm for complete documentation. Basically, with |
| 68 | + just a simple Makefile.PL (such as the one generated by h2xs), you can |
| 69 | + now build an extension from anywhere on your system, even if you've |
| 70 | + deleted the perl source. |
| 71 | + |
| 72 | + Improved build/install documentation in README. A little. |
| 73 | + |
| 74 | + Improved dynamic loading on HP-UX. Support dynamic loading on SVR4. |
| 75 | + |
| 76 | + Installperl now gets the version correct :-) |
| 77 | + |
| 78 | + Installperl now saves the perl *.h files and the libperl.a library |
| 79 | + in your architecture-dependent library directory so that you can |
| 80 | + later build extensions without having to re-install the perl |
| 81 | + source. |
| 82 | + |
| 83 | + Include x2p/a2p.c generated by byacc from x2p/a2p.y. |
| 84 | + |
| 85 | + Many many portability fixes. |
| 86 | + |
| 87 | +Upgrade Traps and Pitfalls: |
| 88 | + |
| 89 | +Since a lot has changed in the build process, you are probably best |
| 90 | +off starting with a fresh copy of the perl5.000 sources. In particular, |
| 91 | +your 5.000 config.sh will contain several variables that are no longer |
| 92 | +needed. Further, improvements in the Configure tests may mean that some |
| 93 | +of the answers will be different than they were in 5.000, and which answer |
| 94 | +to keep can be difficult to sort out. Therefore, you are probably |
| 95 | +better off ignoring your old config.sh. |
| 96 | + |
| 97 | +One big change is that architecture-dependent library files may well |
| 98 | +be stored in a different location in 5.001. This is because the default |
| 99 | +name used in the 5.000 release was not sufficiently specific to |
| 100 | +distinguish incompatible architectures. The relevant variable is $archlib |
| 101 | +in config.sh. Before you run ``make install'' you should rename your old |
| 102 | +$archlib. Thus if your $archlib for version 5.000 was |
| 103 | +/usr/local/lib/perl5/foo, and your new value for 5.001 is |
| 104 | +/usr/local/lib/perl5/foo-bar, then you should |
| 105 | + mv /usr/local/lib/perl5/foo /usr/local/lib/perl5/foo-bar |
| 106 | +before running ``make install''. |
| 107 | + |
| 108 | +Alternatively, you could override Configure's default guess for $archlib |
| 109 | +either by sh Configure -Darchname='foo', or by answering 'foo' when |
| 110 | +prompted by Configure for the architecture name. |
| 111 | + |
| 112 | +The following is the sequence of steps to upgrade to 5.001: |
| 113 | + cd perl5.000 |
| 114 | + make realclean |
| 115 | + rm config.sh |
| 116 | + <apply 5.001 patch> |
| 117 | + sh Configure |
| 118 | + make depend |
| 119 | + make |
| 120 | + make test |
| 121 | + <mv old architecture-dependent library to new location, if needed> |
| 122 | + make install |
| 123 | + |
| 124 | + |
| 125 | + |
| 126 | + |
