1 | This is a first ported perl for the POSIX subsystem in BS2000 VERSION |
2 | 'V121', OSD V3.1, POSIX Shell V03.1A55. It may work on other |
3 | versions, but that's the one we've tested it on. |
4 | |
5 | You may need the following GNU programs in order to install perl: |
6 | |
7 | gzip: |
8 | |
9 | We used version 1.2.4, which could be installed out of the box with |
10 | one failure during 'make check'. |
11 | |
12 | bison: |
13 | |
14 | The yacc coming with BS2000 POSIX didn't work for us. So we had to |
15 | use bison. We had to make a few changes to perl in order to use the |
16 | pure (reentrant) parser of bison. We used version 1.25, but we had to |
17 | add a few changes due to EBCDIC. |
18 | |
19 | |
20 | UNPACKING: |
21 | ========== |
22 | |
23 | To extract an ASCII tar archive on BS2000 POSIX you need an ASCII |
24 | filesystem (we used the mountpoint /usr/local/ascii for this). Now |
25 | you extract the archive in the ASCII filesystem without I/O-conversion: |
26 | |
27 | cd /usr/local/ascii |
28 | export IO_CONVERSION=NO |
29 | gunzip < /usr/local/src/perl.tar.gz | pax -r |
30 | |
31 | You may ignore the error message for the first element of the archive |
32 | (this doesn't look like a tar archive / skipping to next file...), |
33 | it's only the directory which will be made anyway. |
34 | |
35 | After extracting the archive you copy the whole directory tree to your |
36 | EBCDIC filesystem. This time you use I/O-conversion: |
37 | |
38 | cd /usr/local/src |
39 | IO_CONVERSION=YES |
40 | cp -r /usr/local/ascii/perl5.005_02 ./ |
41 | |
42 | |
43 | COMPILING: |
44 | ========== |
45 | |
46 | There is a "hints" file for posix-bc that specifies the correct values |
47 | for most things. The major problem is (of course) the EBCDIC character |
48 | set. |
49 | |
50 | Configure did everything except the perl parser. |
51 | |
52 | Because of our problems with the native yacc we used GNU bison to |
93fb2ac3 |
53 | generate a pure (=reentrant) parser for perly.y. So our yacc is |
54 | really the following script: |
a1a0e61e |
55 | |
93fb2ac3 |
56 | -----8<-----/usr/local/bin/yacc-----8<----- |
57 | #! /usr/bin/sh |
a1a0e61e |
58 | |
93fb2ac3 |
59 | # Bison as a reentrant yacc: |
60 | |
61 | # save parameters: |
62 | params="" |
63 | while [[ $# -gt 1 ]]; do |
64 | params="$params $1" |
65 | shift |
66 | done |
67 | |
68 | # add flag %pure_parser: |
69 | |
70 | tmpfile=/tmp/bison.$$.y |
71 | echo %pure_parser > $tmpfile |
72 | cat $1 >> $tmpfile |
73 | |
74 | # call bison: |
75 | |
76 | echo "/usr/local/bin/bison --yacc $params $1\t\t\t(Pure Parser)" |
77 | /usr/local/bin/bison --yacc $params $tmpfile |
78 | |
79 | # cleanup: |
80 | |
81 | rm -f $tmpfile |
82 | -----8<----------8<----- |
83 | |
84 | We still use the normal yacc for a2p.y though!!! We made a softlink |
85 | called byacc to distinguish between the two versions: |
86 | |
87 | ln -s /usr/bin/yacc /usr/local/bin/byacc |
d5047e56 |
88 | |
93fb2ac3 |
89 | We build perl using both GNU make and the native make. |

91 | |
92 | TESTING: |
93 | ======== |
94 | |
95 | We still got a few errors during 'make test'. Most of them are the |
96 | result of using bison. Bison prints 'parser error' instead of 'syntax |
97 | error', so we may ignore them. One error in the test op/regexp (and |
98 | op/regexp_noamp) seems a bit critical, the result was an 'Out of |
99 | memory' (core dump with op/regexp_noamp). The following list shows |
100 | our errors, your results may differ: |

115 | INSTALLING: |
116 | =========== |
117 | |
118 | We have no nroff on BS2000 POSIX (yet), so we ignored any errors while |
119 | installing the documentation. |
120 | |
121 | |
122 | USING PERL: |
123 | =========== |
124 | |
125 | BS2000 POSIX doesn't support the shebang notation |
126 | ('#!/usr/local/bin/perl'), so you have to use the following lines |
127 | instead: |
128 | |
129 | : # use perl |
130 | eval 'exec /usr/local/bin/perl -S $0 ${1+"$@"}' |
131 | if $running_under_some_shell; |
