1 Current state of the patches here is with respect to perl5.002b1d ;-).
3 ========================================================
5 The OS/2 patchkit was submitted by ilya@math.ohio-state.edu. I have
6 applied some parts that I suspect won't cause any problems.
7 Others do things that I haven't had time to fully consider.
9 Still other patches included here should perhaps be integrated with the
10 metaconfig package that generates Configure.
12 Andy Dougherty <doughera@lafcol.lafayette.edu>
14 ========================================================
18 patches should be applied as
20 All the diff.* files and POSIX.mkfifo should be applied.
22 Additional files are available on
23 ftp://ftp.math.ohio-state.edu/pub/users/ilya/os2
24 including patched pdksh and gnumake, needed for build.
30 This is not supposed to make a perfect Perl on OS/2. This patch is
31 concerned only with perfect _build_ of Perl on OS/2. A lot of good
32 features from Andreas Kaiser port missed this patch.
34 Annotations of changes: (part of what is below is already included by Andy,
35 ~~~~~~~~~~~~~~~~~~~~~~~ thus there are skips below)
42 a) mkfifo macro added to Posix.c
43 b) Copyright notice for OS/2 port changed
44 c) MYMALLOC section in perl.h moved (why?)
45 d) setgrent grent and getgrent wrapped in ifdef
46 e) declarations for #if defined(MYMALLOC) && defined(HIDEMYMALLOC)
48 f) some diagnostics added to tests
51 b) Support for extraction from NE style libraries.
54 lines did not have $ldopts.
55 d) The above variables are used throughout the file for checks
57 3) Build tools and libraries
60 a) ln changed to $ln in some places
61 b) Makefiles and related scripts made to use $(O), $(A), $(AR)
62 using the vars found by Configure or defaulted to
63 some reasonable value.
64 c) $firstmakefile is the file make looks onto before Makefile
65 d) $plibext is the extension for the perl library
66 e) $archobjs is the list of additional object files needed for
68 l) Makefile.SH : added sh in front of some commands
69 if $d_shrplib is 'custom', looks into
70 $osname/Makefile.$osname.SH to construct the section
71 on shared Perl library.
72 !!!!!! Also: installperl installman makedepend
73 !!!!!! added as dependencies to the corresponding
75 m) clean target extended to delete some intermediate files
77 Notes on build on OS/2:
78 ~~~~~~~~~~~~~~~~~~~~~~~
79 The change of C code in this patch is based on the ak port of 5.001+.
81 a) Make sure your sort is not the broken OS/2 one.
83 b) when extraction perl5.*.tar.gz you need to extract perl5.*/Configure
84 separately, since by default perl5.001m/configure overwrites it;
86 tar vzxf perl5.004.tar.gz perl5.004/Configure
88 c) Necessary manual intervention when compiling on OS/2:
90 Need to put perl.dll on LIBPATH after it is created.
94 # Look for hints/os2.sh and correct what is different on your system
95 # I have rather spartan configuration.
97 # Prefix means where to install:
98 sh Configure -des -D prefix=f:/perl5.005
100 # Will probably die after build of miniperl (unless you have DLL
101 # from previous compile). Need to move DLL where it belongs
103 # some warnings in POSIX.c
105 # some tests fail, 9 on my system
107 # before this you should create subdirs bin and lib in the
108 # prefix directory (f:/perl5.005 above):
110 # man pages are not installed
112 e) At the end of August GNU make and pdksh were too buggy for compile.
113 Both maintainers have patches that make it possible to compile perl.
114 The binaries are included in
115 ftp://ftp.math.ohio-state.edu/pub/users/ilya/os2
116 patches are available too.
117 Note that the beta of pdksh5.2.4 can run Configure, but not build, since
119 may actually call file.SH ! The maintainer is notified, I hope this will be
120 fixed before actual release.
123 If you see that some '/' became '\' in pdksh 5.2.3, you did not apply
125 Same with segfaults in Make 3.74.
130 a) one of the latest tr is broken, get an old one :-(
131 1.11 works. (On compuserver?)
132 b) You need a perlglob.exe and link386.
133 c) Get rid of invalid perl.dll on your LIBPATH.
136 Send comments to ilya@math.ohio-state.edu.
138 ======================================================
139 Requires 0.9b (well, provision are made to make it build under 0.9a6,
140 but they are not tested, please inform me on success).
141 (earlier than 0.9b ttyname was not present, it is hard to maintain this
142 difference automatically, though I try).
143 ======================================================
145 You may try building with a.out style by using `-D emxaout' on the Configure
146 line (dynamic extensions should not use CRT (and/or any perl API) in this
147 case, which prohibits most buildin extensions). Probably no extension is
148 possible, since boot code should return the amount on stack.
150 The reason why compiling with a.out style executables leads to problems
151 with dynamic extensions is:
152 a) OS/2 does not export symbols from executables;
153 b) Thus if extension needs to import symbols from an application
154 the symbols for the application should reside in a .dll.
155 c) You cannot export data from a .dll compiled with a.out style.
156 On the other hand, aout-style compiled extension enjoys all the
157 (dis)advantages of fork().
