1 | This is a fully ported perl for OS/390 Release 3. It may work on |
2 | other versions, but that's the one we've tested it on. | |
3 | ||
4 | If you've downloaded the binary distribution, it needs to be | |
5 | installed below /usr/local. Source code distributions have an | |
6 | automated `make install` step that means you do not need to extract | |
7 | the source code below /usr/local (though that is where it will be | |
8 | installed by default). You may need to worry about the networking | |
9 | configuration files discussed in the last bullet below. | |
10 | ||
11 | Gunzip/gzip for OS/390 is discussed at: | |
12 | ||
13 | http://www.s390.ibm.com/products/oe/bpxqp1.html | |
14 | ||
15 | to extract an ASCII tar archive on OS/390, try this: | |
16 | ||
17 | pax -o to=IBM-1047,from=ISO8859-1 -r < latest.tar | |
18 | ||
19 | GNU make for OS/390, which may be required for the build of perl, | |
20 | is available from: | |
21 | ||
22 | http://www.mks.com/s390/gnu/index.htm | |
23 | ||
24 | Once you've unpacked the distribution, run Configure (see INSTALL for | |
25 | full discussion of the Configure options), and then run make, then | |
26 | "make test" then "make install" (this last step may require UID=0 | |
27 | privileges) | |
28 | ||
29 | There is a "hints" file for os390 that specifies the correct values | |
30 | for most things. Some things to watch out for are | |
31 | ||
32 | - this port doesn't support dynamic loading. Although | |
33 | OS/390 has support for DLLs, there are some differences | |
34 | that cause problems for perl. | |
35 | ||
36 | - You may see a "WHOA THERE!!!" message for $d_shmatprototype | |
37 | it is OK to keep the recommended "define". | |
38 | ||
39 | - Don't turn on the compiler optimization flag "-O". There's | |
40 | a bug in either the optimizer or perl that causes perl to | |
41 | not work correctly when the optimizer is on. | |
42 | ||
43 | - Some of the configuration files in /etc used by the | |
44 | networking APIs are either missing or have the wrong | |
45 | names. In particular, make sure that there's either | |
46 | an /etc/resolv.conf or and /etc/hosts, so that | |
47 | gethostbyname() works, and make sure that the file | |
48 | /etc/proto has been renamed to /etc/protocol (NOT | |
49 | /etc/protocols, as used by other Unix systems). | |
50 | ||

51 | - Some of the parser default files in /sample are needed in /etc. |
52 | In particular be sure that you at least copy /sample/yy* to /etc | |
53 | before running perl's Configure. | |
54 | ||

55 | When using perl on OS/390 please keep in mind that the EBCDIC and ASCII |
56 | character sets are different. Perl builtin functions that may behave | |
57 | differently under EBCDIC are mentioned in the perlport.pod document. | |
58 | ||
59 | OpenEdition (UNIX System Services) does not (yet) support the #! means | |
60 | of script invokation. | |
61 | See: | |
62 | ||
63 | head `whence perldoc` | |
64 | ||
65 | for an example of how to use the "eval exec" trick to ask the shell to | |
66 | have perl run your scripts for you. | |
67 | ||
68 | perl-mvs mailing list: The Perl Institute (http://www.perl.org/) | |
69 | maintains a mailing list of interest to all folks building and/or | |
70 | using perl on EBCDIC platforms. To subscibe, send a message of: | |
71 | ||
72 | subscribe perl-mvs | |
73 | ||
74 | to majordomo@perl.org. | |
75 | ||
76 | Regression tests: as the 5.005 kit was was being assembled | |
77 | the following "failures" were known to appear on some machines | |
78 | during `make test` (mostly due to ASCII vs. EBCDIC conflicts), | |
79 | your results may differ: | |
