2 | # QNX hints |
3 | # |

4 | # These hints were written for QNX4, but are in the process |
5 | # of being extended to encompass Neutrino as well. |

7 | # As of perl5.004_04, all tests pass under: |
8 | # QNX 4.23A |
9 | # Watcom 10.6 with Beta/970211.wcc.update.tar.F |
10 | # socket3r.lib Nov21 1996. |
af23fe4d |
11 | # perl-5.6.1 runs well on QNX4 with a few known test failures |
12 | # perl-5.6.0 ships with QNX RTP (Neutrino) but the build is |
13 | # not yet straightforward. |
ff68c719 |
14 | # |
15 | # As with many unix ports, this one depends on a few "standard" |
af23fe4d |
16 | # unix utilities which are not necessarily standard for QNX4. |
ff68c719 |
17 | # |
18 | # /bin/sh This is used heavily by Configure and then by |
af23fe4d |
19 | # perl itself. QNX4's version is fine, but Configure |
ff68c719 |
20 | # will choke on the 16-bit version, so if you are |
21 | # running QNX 4.22, link /bin/sh to /bin32/ksh |
22 | # ar This is the standard unix library builder. |
23 | # We use wlib. With Watcom 10.6, when wlib is |
24 | # linked as "ar", it behaves like ar and all is |
25 | # fine. Under 9.5, a cover is required. One is |
26 | # included in ../qnx |
27 | # nm This is used (optionally) by configure to list |
28 | # the contents of libraries. I will generate |
29 | # a cover function on the fly in the UU directory. |
30 | # cpp Configure and perl need a way to invoke a C |
31 | # preprocessor. I have created a simple cover |
32 | # for cc which does the right thing. Without this, |
022735b4 |
33 | # Configure will create its own wrapper which works, |
ff68c719 |
34 | # but it doesn't handle some of the command line arguments |
35 | # that perl will throw at it. |
36 | # make You really need GNU make to compile this. GNU make |
37 | # ships by default with QNX 4.23, but you can get it |
38 | # from quics for earlier versions. |

40 | # Outstanding Issues for QNX4: |
41 | # There is no support for dynamically linked libraries in |
42 | # QNX4. |
43 | # |
44 | # ext/Cwd/Cwd.t will complain if `pwd` and cwd don't give |
45 | # the same results. cwd calls `fullpath -t`, so if you |
46 | # cd `fullpath -t` before running the test, it will |
47 | # pass. |
48 | # |
49 | # lib/File/Find/taint.t will complain if '.' is in your |
50 | # PATH. The PATH test is triggered because cwd calls |
51 | # `fullpath -t`. |
52 | # |
53 | # lib/ExtUtils.t: If you follow these hints and include |
54 | # -w4 in your ccflags, this test will complain about |
55 | # extra .err files appearing in its test directory. |
56 | # |
57 | # ext/IO/lib/IO/t/io_sock.t Still investigating |
58 | # ext/POSIX/sigaction.t Still investigating |
59 | # |
60 | # Older issues: |
61 | # lib/posix.t test failed on test 17 because acos(1) != 0. |
4f6a2eb2 |
62 | # Resolved in 970211 Beta |
ff68c719 |
63 | # lib/io_udp.t test hangs because of a bug in getsockname(). |
64 | # Fixed in latest BETA socket3r.lib |
