The following modifications needed to be made to the perl (Release 3 patchlevel 28) source to compile on an IBM RS/6000 running AIX 3.01: I am posting this: (a) for your information (b) for your ideas - particularly about problem 4. below. 1. in x2p/util.c the AIX xlc compiler throws up on: #ifdef undef ...it regards 'undef' as a illegal keyword I changed `undef' to `UNDEF' 2. in perl.h can't redefine sprintf(). Enclose within #ifndef AIX / #endif pair (and add -DAIX to CFLAGS in the makefile) 3. in doio.c In the conditional compilation determined by PWCLASS, the code assumes that if pw_class is not present, then pw_comment is. This is not true for AIX. I have set it to pw_gecos for want of a better idea. 4. in eval.c The compiler complains about multiple instances of the `case' 32 in the big switch statement. This appears to be a bug in the compiler, since inspection of the preprocessor output confirms that there is only one instance of the case '32'. Changing the definition of O_COMPLEMENT from 32 to 247 made the problem disappear. With the above mods, perl compiles and links. Doing 'make test' shows that this version of perl fails the following tests: io.pipe test 1 op.exec test 8 the others are ok. Since i am a perl novice, i haven't looked closely at this. rab ------------------------------------------------------------------------ Richard Brown | E-mail: rab@tauon.ph.unimelb.EDU.AU School of Physics | Phone : +61 3 344 5081 University of Melbourne | Fax : +61 3 347 4783 Parkville Victoria AUSTRALIA 3052 | Telex : AA35185

Some of the problems you reported building perl at patchlevel 28 have been
addressed in later versions of perl. Here is a recipe for building perl at
patchlevel 44 on AIX 3.1 (3001) that passes all tests in "make test". Note
that "cc", not "xlc" or "bsdcc" is used.
o used perl-3.0.41.tar.Z from prep.ai.mit.edu
o applied patches 42, 43, & 44
o ./Configure
Default answer on all questions, EXCEPT:
"Do you wish to attempt to use the malloc that comes with perl? [y] n"
o apply attached patch which:
o defines SYMLINK in config.h
o prevents redefintion of sprintf in perl.h
o inserts "#pragma alloca" in x2p/a2p.y
o make depend
o make
o make test
o make install

The patches are available from uunet.uu.net, prep.ai.mit.edu and jpl-devvax.jpl.nasa.gov via anonymous ftp. _Many_ fixes have been made since pl28. Anyway, perl3@44 compiles quite nicely on the '6000 with just one fix in malloc.c. If you answered 'no' the the question 'Do you wish to use the malloc that comes with perl?', then perl compiles clean right out of the box and passes all the tests. If you answered 'yes', then all you need do is change the declaration of free in malloc.c to be 'void free(cp) void * cp;' instead of the supplied 'free(cp) char * cp;' This is because the stdlib.h supplied with the '6000 uses the POSIX/ANSI definition of free and would not allow it to be redeclared with a different signature. +--Marc Pawliger----IBM Advanced Workstations Division----Palo Alto, CA---+ | Internet: marc@ibminet.awdpa.ibm.com VNET: MARCP at AUSVM6 | | UUCP: uunet!ibminet.awdpa.ibm.com!marc Phone: (415) 855-3493 | +-----IBMinet: marc@ibmpa.awdpa.ibm.com----------IBM T/L: 465-3493------+ As always, these are my opinions and not IBM's etc etc etc
