3========================================================

5The OS/2 patchkit was submitted by ilya@math.ohio-state.edu. I have
6applied some parts that I suspect won't cause any problems.
7Others do things that I haven't had time to fully consider.
8
9Still other patches included here should perhaps be integrated with the
10metaconfig package that generates Configure.

16Notes on the patch:
17~~~~~~~~~~~~~~~~~~~
18patches should be applied as
19 patch -p0 <.....
20All the diff.* files and POSIX.mkfifo should be applied.
21
22Additional files are available on
23 ftp://ftp.math.ohio-state.edu/pub/users/ilya/os2
24including patched pdksh and gnumake, needed for build.

27Target:
28~~~~~~~
29
30This is not supposed to make a perfect Perl on OS/2. This patch is
31concerned only with perfect _build_ of Perl on OS/2. Some good
32features from Andreas Kaiser port missed this port. However, most of
33the features are available in different form.
34
35!!! Note that [gs]etpriority functions in this port are compatible
36!!! with *nix, not with ak's port!!!
37
38The priorities are absolute, go from 32 to -95, lower is quickier. 0
39is default,

41Notes on build on OS/2:
42~~~~~~~~~~~~~~~~~~~~~~~
43The change of C code in this patch is based on the ak port of 5.001+.
44
45a) Make sure your sort is not the broken OS/2 one, and that you have /tmp
46on the build partition.
47
48b) when extracting perl5.*.tar.gz you need to extract perl5.*/Configure
49separately, since by default perl5.001m/configure may overwrite it;
50 like this:
51 tar vzxf perl5.004.tar.gz --case-sensitive perl5.004/Configure
52
53c) Necessary manual intervention when compiling on OS/2:
54
55 Need to put perl.dll on LIBPATH after it is created.
56
57d) Compile summary:
58 ~~~~~~~~~~~~~~~
59!!! At the end of this README is independent description of the build
60!!! process by Rocco Caputo.
61
62# Look for hints/os2.sh and correct what is different on your system
63# I have rather spartan configuration.
64
65 # Prefix means where to install:
66sh Configure -des -D prefix=f:/perl5.005
67 # Ignore the message about missing `ln', and about `c' option
68 # to tr.
69make
70 # Will probably die after build of miniperl (unless you have DLL
71 # from previous compile). Need to move DLL where it belongs
72 #
73 # Somehow with 5.002b3 I needed to type another make after pod2man
74make
75 # some warnings in POSIX.c
76make test
77 # some tests fail, 9 or 10 on my system (see the list at end).
78 #
79 # before this you should create subdirs bin and lib in the
80 # prefix directory (f:/perl5.005 above):
81 #
82 # To run finer tests, cd t && perl harness
83make install
84
85e) At the end of August GNU make and pdksh were too buggy for compile.
86Both maintainers have patches that make it possible to compile perl.
87The binaries are included in
88 ftp://ftp.math.ohio-state.edu/pub/users/ilya/os2
89patches are available too.
90Note that the pdksh5.2.4 broke builds with -Zexe option because of a
91changed order of executable extensions. A patch is sent to
92maintainer. The version 5.2.5alpha was OK for the build,
93
94!!!!!!!!!!!!!!!!!
95If you see that some '/' became '\' in pdksh 5.2.3, you did not apply
96my patches!
97Same with segfaults in Make 3.74.
98!!!!!!!!!!!!!!!!!
99
100Problems reported:
101
102a) one of the latest tr is broken, get an old one :-(
103 1.11 works. (On compuserver?)
104b) You need a link386.
105c) Get rid of invalid perl.dll on your LIBPATH.
106
107Note the EMX does not support en_us locale (most nobody does ;-). Some
108TCP/IP update could have installed it to your config.sys. You need to
109delete it until EMX is updated to support this newest discovery by IBM.

113
114======================================================
115Requires 0.9b (well, provision are made to make it build under 0.9a6,
116but they are not tested, please inform me on success).
117(earlier than 0.9b ttyname was not present, it is hard to maintain this
118difference automatically, though I try).
119======================================================
120
121Building with a.out style is supported by the `perl_' target of make.
122Dynamic extensions are not possible with perl_.exe, since boot code
123should return the retvalue on stack, the address of which is not known
124to the extension.
125
126The reason why compiling with a.out style executables leads to problems
127with dynamic extensions is:
128 a) OS/2 does not export symbols from executables;
129 b) Thus if extension needs to import symbols from an application
130 the symbols for the application should reside in a .dll.
131 c) You cannot export data from a .dll compiled with a.out style.
132On the other hand, aout-style compiled extension enjoys all the
133(dis)advantages of fork().
134
135Check A.OUT compile with the following make targets:
136
137 aout_test
138 aout_install
139 aout_clean
140
141======================================================
142Tests which fail with OMF compile:
143
144io/fs.t: 2-5, 7-11, 18 as they should.
145io/pipe: all, since open("|-") is not working (works with perl_.exe).
146lib/"all the dbm".t: 1 test should fail (file permission).
147op/fork all fail, as they should (except with perl_.exe)
148op/stat 3 20 35 as they should, 39 (-t on /dev/null) ???? Sometimes 4
149- timing problem ????
150
151Sometimes I have seen segfault in socket ????, only if run with Testing tools.
152
153A lot of `bad free'... in databases, bug in DB confirmed on other
154platforms.
155
156Fail: Total 30 subtests (if stat:4 fails) in 10 scripts (one of 10
157is socket, which runs OK standalone). With newer configs I could not
158reproduce most the crashes.
159
160=======================================================
161
162Changes to calls to external programs:
163~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Due to a popular demand the perl
164external program calling has been changed. _If_ perl needs to call an
165external program _via shell_, the X:/bin/sh.exe will be called. The
166name of the shell is not overridable, except the drive letter.
167
168Thus means that you need to pickup some copy of a sh.exe as well (I use one
169from pdksh). The drive X: above is set up automatically during the
170build, is settable in runtime from $ENV{PERL_SH_DRIVE}.
171
172Reasons: a consensus on perl5-porters was that perl should use one
173non-overridable shell per platform. The obvious choices for OS/2 are cmd.exe
174and sh.exe. Having perl build itself would be impossible with cmd.exe as
175a shell, thus I picked up sh.exe. Thus assures almost 100% compatibility
176with the scripts coming from *nix.
177
178Disadvantages: sh.exe calls external programs via fork/exec, and there is
179_no_ functioning exec on OS/2. exec is emulated by EMX by asyncroneous call
180while the caller waits for child completion (to pretend that pid did
181not change). This means that 1 _extra_ copy of sh.exe is made active via
182fork/exec, which may lead to some resources taken from the system.
183
184The long-term solution proposed on p5-p is to have a directive
185 use OS2::Cmd;
186which will override system(), exec(), ``, and open(,' |'). With current
187perl you may override only system(), readpipe() - the explicit version
188of ``, and maybe exec(). The code will substitute a one-argument system
189by CORE::system('cmd.exe', '/c', shift).
190
191If you have some working code for OS2::Cmd.pm, please send it to me,
192I will include it into distribution. I have no need for such a module, so
193cannot test it.
194
195===================================================
196
197OS/2 extensions
198~~~~~~~~~~~~~~~
199Since binaries cannot go into perl distribution, no extensions are
200included. They are available in .../os2/ilyaz directory of CPAN, as
201well as in my directory
202 ftp://ftp.math.ohio-state.edu/pub/users/ilya/os2
203
204I include 3 extensions by Andread Kaiser, OS2::REXX, OS2::UPM, and OS2::FTP,
205into my ftp directory, mirrored on CPAN. I made
206some minor changes needed to compile them by standard tools. I cannot
207test UPM and FTP, so I will appreciate your feedback. Other extensions
208there are OS2::ExtAttribs, OS2::PrfDB for tied access to EAs and .INI
209files - and maybe some other extensions at the time you read it.
210
211Note that OS2 perl defines 2 pseudo-extension functions
212OS2::Copy::copy and DynaLoader::mod2fname.
213
214The -R switch of older perl is deprecated. If you need to call a REXX code
215which needs access to variables, include the call into a REXX compartment
216created by
217 REXX_call {...block...};
218
219Two new functions are supported by REXX code,
220 REXX_eval 'string';
221 REXX_eval_with 'string', REXX_function_name => \&perl_sub_reference;
222
223If you have some other extensions you want to share, send the code to me.
224Two jump to mind: tied access to EA's, and tied access to system databases.

232Starting in x:/usr/src, using 4OS2/32 2.5 as the command interpreter on
233OS/2 2.30 with FixPak-17. DAX is installed, but this shouldn't be a
234factor. Drive X is a TVFS virtual drive pointing to several physical
235HPFS drives.
236
237>>> Make sure that no copies or perl are currently running. Miniperl
238 may fail during the build because it will find an older version
239 of perl.dll loaded in memory.
240
241 Close any running perl scripts.
242 Shut down anything that might run perl scripts, like cron.
243 `emxload -l` to check for loaded versions of perl.
244 `emxload -u perl.exe` to unload them.
245
246>>> Pre-load some common utilities:
247
248 emxload -e sh.exe make.exe ls.exe tr.exe id.exe sed.exe
249 SET GCCLOAD=30 (number of minutes to hold the compiler)
250[grep egrep fgrep cat rm uniq basename uniq sort - are not bad too.]
251 The theory is that it's faster to demand-load the development tools
252 from virtual memory than it is to re-load and re-link them all the
253 time. This is definitely true with my system because swapfile.dat
254 is on a faster drive than my development environment.
255
256 ls, tr, and id represent the GNU file, text, and shell utilities.
257 These may not be needed, but it makes sure that their respective
258 DLLs are in memory.
259
260>>> Unpack the perl 5_002_01 archive onto an HPFS partition.
261
262 tar vxzf perl5_002_01.tar-gz
263 cd perl5.002_01
264
265[Do not forget to extract Configure as described above.]

274 patch -p0 < os2\POSIX.mkfifo
275
276[The patch below is already applied.]
277
278>>> You may need to apply this patch if you plan to run a non-standard
279 Configure (that is, if you defy the README). This patch will ensure
280 that Makefile inherits the libraries specified during Configure.
281 People running standard perl builds can probably ignore this patch.

323
324>>> Run Configure. Most people can run it by following the README:
325
326 sh Configure -des -D prefix=f:/usr/local
327
328 Advanced perl users (experienced C programmers, recommended) can run
329 the interactive Configure and answer the questions. When in doubt
330 about an answer, check the EMX headers and documentation. Pick the
331 default answer if that doesn't help:
332
333 sh Configure
334
335[Yet more advanced users just specify the answers on the command line
336of Configure, like I did with prefix.]
337
338 Note: You may need to wrap an answer in quotes if it contains
339 spaces. For example, "-lsocket -lm".
340
341 Note: If you want to add some options to a long default, you can
342 use $* to include the default in your answer: "$* -DDEBUGGING".
343
344 Configure warnings and errors, and possible work-arounds:
345
346 I don't know where 'ln' is....
347 (ignored; OS/2 doesn't have a ln command)
348
349 nm didn't seem to work right. Trying emxomfar instead...
350 (nothing to worry about)
351
352 The recommended value for $d_shrplib on this machine was "define"!
353 (kept the recommended value: y)
354
355 Directory f:/usr/lib/perl5/os2/5.00201/CORE doesn't exist.
356 (created the directory from another window with
357 \usr\bin\mkdir -p f:/usr/lib/perl5/os2/5.00201/CORE
358 and then answered: y. Your directory may look different.)
359
360[Ignore this as well, install script will create it for you.]
361
362 The recommended value for $i_dlfcn on this machine was "define"!
363 (kept the recommended value: y)
364
365 The recommended value for $d_fork on this machine was "undef"!
366 (kept the recommended value: y)
367
368 Figuring out the flag used by open() for non-blocking I/O...
369 Seems like we can use O_NONBLOCK.
370 This seems to be used for informative purposes only.
371 The errors that follow this (including a SIGPIPE) don't seem
372 to affect perl at all. These were safely ignored.
373
374 What pager is used on your system? [/usr/ucb/more]
375 Had to answer "/usr/bin/less.exe" because Configure wants a
376 leading / (unix full path). Need to edit config.sh later with
377 the real full path to the pager, including the drive letter.
378
379[Apparently this setting is never used, so it is safe to ignore it.]
380
381 Hmm... F:/USR/BIN/sed: Unterminated `s' command
382 Perl built fine even with this error, so it seems safe to
383 ignore.
384
385 Things I did different from the defaults. Most (if not all) of these
386 are optional changes. They're listed here to show how good Configure
387 is at detecting the system setup.
388
389[I add the options to put it on command line of Configure, see below.]
390
391 Selected 'none' for the man1 location.
392 (I prefer the pod2html version.)
393[-D man1dir=none]
394 Selected 'none' for the man3 location.
395 (I prefer the pod2html version.)
396[-D man3dir=none]
397 Changed the hostname and domain.
398 (I wanted to override a dynamic PPP address. This only
399 matters if other people will be using your perl build.)
400[-D myhostname=my_host_name -D mydomain=.foo.org]
401 Fixed the e-mail address.
402 (Put in a known working e-mail address. This only matters
403 if other people will be using your perl build.)
404[-D cf_email=root@myhostname.uucp]
405 Added some directories to the library search path.
406[-D "libpth=f:/emx/lib/st f:/emx/lib"]
407 Added -g to the optimizer/debugger flags.
408[-D optimize=-g]
409 Added "-lgdbm -ldb -lcrypt -lbsd" to the additional libraries.
410[ -D "libs=-lsocket -lcrypt -lgdbm"
411 the rest of libraries will not be used]
412
413>>> Advanced users may want to edit config.sh when prompted by Configure.
414 Most (all?) of these changes aren't really necessary:
415
416 d_getprior='define'
417 d_setprior='define'
418 (getpriority and setpriority are included in os2.c, but
419 Configure doesn't know to look there.)
420[fixed already]
421 pager='f:/usr/bin/less.exe'
422 (Correcting Configure's insistence on a leading slash.)
423 bin_sh='f:/usr/bin/sh.exe'
424 (If Configure detects sh.exe somewhere else first. Example:
425 it saw sh.exe at /bin/sh.exe on my TVFS drive, but I want
426 perl to look for it on the physical F drive.)
427 aout_ccflags='... existing flags... -DDEBUGGING'
428 aout_cppflags='... existing flags... -DDEBUGGING'
429 (If you want to include DEBUGGING for the aout version.)
430[Do not do it, -D optimize=-g will automatically add these flags.]
431
432>>> Allow Configure to make the build scripts.
433
434>>> Allow Configure to run `make depend`. Ignore the following warning:
435
436 perl.h:861: warning: `DEBUGGING_MSTATS' redefined
437[corrected now]
438
439>>> Rename any existing perl.dll, preventing anything from loading it and

455
456>>> If `make` dies while "Making DynaLoader (static)", you'll need to
457 put miniperl in the OS/2 paths. This step is only necessary if `make`
458 can't find miniperl:
459[I would be interested if somebody confirmes this.]
460
461 cp perl.dll /usr/lib (where /usr/lib is in your LIBPATH)
462 cp miniperl.exe /usr/bin (where /usr/bin is in your PATH)
463 make (ignore the errors in the previous step)
464
465 This should run to completion.
466
467>>> Test the build:
468
469 make test
470
471 These tests fail:
472
473 io/fs..........FAILED on test 2
474
475 "OS/2 is not unix". Test 2 checks the link() command, which
476 is not supported by OS/2.
477
478 io/pipe........f:/usr/bin/sh.exe: -c requires an argument
479 f:/usr/bin/sh.exe: -c requires an argument
480 The Unsupported function fork function is unimplemented at
481 io/pipe.t line 26.
482 FAILED on test 1
483
484 More "OS/2 is not unix" errors. Read ahead to find out
485 why fork() fails.
486
487 op/exec........FAILED on test 4
488
489 if (system "true") {print "not ok 4\n";} else \
490 {print "ok 4\n";}
491
492 This fails for me, but changing it to read like this works:
493
494 if (system '\usr\bin\true.cmd') {print "not ok 4\n";} \
495 else {print "ok 4\n";}
496
497 So you can count this as another "OS/2 is not unix".

529 is not unix" so the permissions aren't exactly what this test
530 expects.

571 Failed 11/94 tests, 88.30% okay.
572
573 All of which are known differences with unix or documented
574 behaviors in EMX. I re-run the test with Ilya's version,
575 and the same tests fail. This new build is a success.
576[Note that bad free() mentioned above are bugs in the Berkeley
577DB. They just are more visible under OS/2 with perl free(), because of
578"rigid" function name resolution.
579 To get finer tests, cd to ./t and run
580 perl harness
581]
582
583 (Actually, Ilya's perl release fails an extra test because I don't
584 have sed in f:\emx.add. This shows how important it is to configure
585 and build perl yourself instead of grabbing pre-built binaries.)
586[Hmm, should not happen... There is no mentions of full_sed under ./t
587directory...]

593 Warnings encountered and workarounds presented.:
594
595 WARNING: You've never run 'make test'!!! (Installing anyway.)
596 (Lies! All lies! At least it still installs.)
597
598 WARNING: Can't find libperl*.dll* to install into \
599 f:/usr/lib/perl5/os2/5.00201/CORE. (Installing other things anyway.)
600 (Safe to ignore. The important one, libperl.lib, gets copied.)
601
602 Couldn't copy f:/usr/bin/perl5.00201.exe to f:/usr/bin/perl.exe: \
603 No such file or directory
604 cp /usr/bin/perl5.00201.exe /usr/bin/perl.exe
605
606 Couldn't copy f:/usr/bin/perl.exe to /usr/bin/perl.exe: No such \
607 file or directory
608 (I think this one is safe to ignore since the two directories
609 point to the same place.)
610
611>>> Laugh maniacally because you just built and installed your own copy
612 of perl, with all the paths set "just so" and with whatever little
613 psychotic modifications you've always wanted but were afraid to add.
