|

|
---|
| 7 | perldos - Perl under DOS, W31, W95.
|
---|
| 8 |
|
---|
| 9 | =head1 SYNOPSIS
|
---|
| 10 |
|
---|
| 11 | These are instructions for building Perl under DOS (or w??), using
|
---|
| 12 | DJGPP v2.01 or later. Under w95 long filenames are supported.
|
---|
| 13 |
|
---|
| 14 | =head1 DESCRIPTION
|
---|
| 15 |
|
---|
| 16 | Before you start, you should glance through the README file
|
---|
| 17 | found in the top-level directory where the Perl distribution
|
---|
| 18 | was extracted. Make sure you read and understand the terms under
|
---|
| 19 | which this software is being distributed.
|
---|
| 20 |
|
---|
| 21 | This port currently supports MakeMaker (the set of modules that
|
---|
| 22 | is used to build extensions to perl). Therefore, you should be
|
---|
| 23 | able to build and install most extensions found in the CPAN sites.

| 29 | =item DJGPP
|
---|
| 30 |
|
---|
| 31 | DJGPP is a port of GNU C/C++ compiler and development tools to 32-bit,
|
---|
| 32 | protected-mode environment on Intel 32-bit CPUs running MS-DOS and compatible
|
---|
| 33 | operating systems, by DJ Delorie <dj@delorie.com> and friends.
|
---|
| 34 |
|
---|
| 35 | For more details (FAQ), check out the home of DJGPP at:
|
---|

|
---|
| 37 | http://www.delorie.com/djgpp/
|
---|
| 38 |
|
---|
| 39 | If you have questions about DJGPP, try posting to the DJGPP newsgroup:
|
---|
| 40 | comp.os.msdos.djgpp, or use the email gateway djgpp@delorie.com.
|
---|
| 41 |
|
---|
| 42 | You can find the full DJGPP distribution on any SimTel.Net mirror all over
|
---|
| 43 | the world. Like:
|

---|
| 45 | ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2*
|
---|
| 46 |
|
---|
| 47 | You need the following files to build perl (or add new modules):

| 71 | =head2 Shortcomings of Perl under DOS
|
---|
| 72 |
|
---|
| 73 | Perl under DOS lacks some features of perl under UNIX because of
|
---|
| 74 | deficiencies in the UNIX-emulation, most notably:
|
---|
| 75 |
|
---|
| 76 | =over 4
|
---|
| 77 |
|
---|
| 78 | =item *
|
---|
| 79 |
|
---|
| 80 | fork() and pipe()
|
---|
| 81 |
|
---|
| 82 | =item *
|
---|
| 83 |
|
---|
| 84 | some features of the UNIX filesystem regarding link count and file dates
|
---|
| 85 |
|
---|
| 86 | =item *
|
---|
| 87 |
|
---|
| 88 | in-place operation is a little bit broken with short filenames
|
---|
| 89 |
|
---|
| 90 | =item *
|
---|
| 91 |
|
---|
| 92 | sockets

| 98 | =over 4
|
---|

|
---|
| 100 | =item *
|
---|
| 101 |
|
---|
| 102 | Unpack the source package F<perl5.6*.tar.gz> with djtarx. If you want
|
---|
| 103 | to use long file names under w95, don't forget to use
|
---|
| 104 |
|
---|
| 105 | set LFN=y
|
---|
| 106 |
|
---|
| 107 | before unpacking the archive.
|
---|
| 108 |
|
---|
| 109 | =item *
|
---|
| 110 |
|
---|
| 111 | Create a "symlink" or copy your bash.exe to sh.exe in your C<($DJDIR)/bin>
|
---|
| 112 | directory.
|
---|
| 113 |
|
---|
| 114 | ln -s bash.exe sh.exe
|
---|
| 115 |
|
---|
| 116 | And make the C<SHELL> environment variable point to this F<sh.exe>:
|
---|
| 117 |
|
---|
| 118 | set SHELL=c:/djgpp/bin/sh.exe (use full path name!)
|
---|
| 119 |
|
---|
| 120 | You can do this in F<djgpp.env> too. Add this line BEFORE any section
|
---|
| 121 | definition:
|
---|
| 122 |
|
---|
| 123 | +SHELL=%DJDIR%/bin/sh.exe
|
---|
| 124 |
|
---|
| 125 | =item *
|
---|
| 126 |
|
---|
| 127 | If you have F<split.exe> and F<gsplit.exe> in your path, then rename
|
---|
| 128 | F<split.exe> to F<djsplit.exe>, and F<gsplit.exe> to F<split.exe>.
|
---|
| 129 | Copy or link F<gecho.exe> to F<echo.exe> if you don't have F<echo.exe>.
|
---|
| 130 | Copy or link F<gawk.exe> to F<awk.exe> if you don't have F<awk.exe>.
|
---|
| 131 |
|
---|
| 132 | =item *
|
---|
| 133 |
|
---|
| 134 | Chdir to the djgpp subdirectory of perl toplevel and type the following
|
---|
| 135 | command:
|
---|
| 136 |
|
---|
| 137 | configure.bat
|
---|
| 138 |
|
---|
| 139 | This will do some preprocessing then run the Configure script for you.
|
---|
| 140 | The Configure script is interactive, but in most cases you
|
---|
| 141 | just need to press ENTER.
|
---|
| 142 |
|
---|
| 143 | If the script says that your package is incomplete, and asks whether
|
---|
| 144 | to continue, just answer with Y (this can only happen if you don't use
|
---|
| 145 | long filenames).
|
---|
| 146 |
|
---|
| 147 | When Configure asks about the extensions, I suggest IO and Fcntl,
|
---|
| 148 | and if you want database handling then SDBM_File or GDBM_File
|
---|
| 149 | (you need to install gdbm for this one). If you want to use the
|
---|
| 150 | POSIX extension (this is the default), make sure that the stack
|
---|
| 151 | size of your F<cc1.exe> is at least 512kbyte (you can check this
|
---|
| 152 | with: C<stubedit cc1.exe>).
|
---|
| 153 |
|
---|
| 154 | You can use the Configure script in non-interactive mode too.
|
---|
| 155 | When I built my F<perl.exe>, I used something like this:
|
---|
| 156 |
|
---|
| 157 | configure.bat -des
|
---|
| 158 |
|
---|
| 159 | You can find more info about Configure's command line switches in
|
---|
| 160 | the F<INSTALL> file.
|
---|
| 161 |
|
---|
| 162 | When the script ends, and you want to change some values in the
|
---|
| 163 | generated F<config.sh> file, then run
|
---|
| 164 |
|
---|
| 165 | sh Configure -S
|
---|
| 166 |
|
---|
| 167 | after you made your modifications.
|
---|
| 168 |
|
---|
| 169 | IMPORTANT: if you use this C<-S> switch, be sure to delete the CONFIG
|
---|
| 170 | environment variable before running the script:
|
---|
| 171 |
|
---|
| 172 | set CONFIG=
|
---|
| 173 |
|
---|
| 174 | =item *
|
---|
| 175 |
|
---|
| 176 | Now you can compile Perl. Type:
|
---|
| 177 |
|
---|
| 178 | make
|
---|
| 179 |
|
---|
| 180 | =back
|
---|
| 181 |
|
---|
| 182 | =head2 Testing
|
---|
| 183 |
|
---|
| 184 | Type:
|
---|
| 185 |
|
---|
| 186 | make test
|
---|
| 187 |
|
---|
| 188 | If you're lucky you should see "All tests successful". But there can be
|
---|
| 189 | a few failed subtests (less than 5 hopefully) depending on some external
|
---|
| 190 | conditions (e.g. some subtests fail under linux/dosemu or plain dos
|
---|
| 191 | with short filenames only).
|
---|
| 192 |
|
---|
| 193 | =head2 Installation
|
---|
| 194 |
|
---|
| 195 | Type:
|
---|
| 196 |
|
---|
| 197 | make install
|
---|
| 198 |
|
---|
| 199 | This will copy the newly compiled perl and libraries into your DJGPP
|
---|
| 200 | directory structure. Perl.exe and the utilities go into C<($DJDIR)/bin>,
|
---|
| 201 | and the library goes under C<($DJDIR)/lib/perl5>. The pod documentation
|
---|
| 202 | goes under C<($DJDIR)/lib/perl5/pod>.
