2 | # QNX hints |

4 | # As of perl5.004_04, all tests pass under: |
5 | # QNX 4.23A |
6 | # Watcom 10.6 with Beta/970211.wcc.update.tar.F |
7 | # socket3r.lib Nov21 1996. |
ff68c719 |
8 | # |
9 | # As with many unix ports, this one depends on a few "standard" |
10 | # unix utilities which are not necessarily standard for QNX. |
11 | # |
12 | # /bin/sh This is used heavily by Configure and then by |
13 | # perl itself. QNX's version is fine, but Configure |
14 | # will choke on the 16-bit version, so if you are |
15 | # running QNX 4.22, link /bin/sh to /bin32/ksh |
16 | # ar This is the standard unix library builder. |
17 | # We use wlib. With Watcom 10.6, when wlib is |
18 | # linked as "ar", it behaves like ar and all is |
19 | # fine. Under 9.5, a cover is required. One is |
20 | # included in ../qnx |
21 | # nm This is used (optionally) by configure to list |
22 | # the contents of libraries. I will generate |
23 | # a cover function on the fly in the UU directory. |
24 | # cpp Configure and perl need a way to invoke a C |
25 | # preprocessor. I have created a simple cover |
26 | # for cc which does the right thing. Without this, |
27 | # Configure will create it's own wrapper which works, |
28 | # but it doesn't handle some of the command line arguments |
29 | # that perl will throw at it. |
30 | # make You really need GNU make to compile this. GNU make |
31 | # ships by default with QNX 4.23, but you can get it |
32 | # from quics for earlier versions. |
33 | #---------------------------------------------------------------- |
34 | # Outstanding Issues: |
35 | # lib/posix.t test fails on test 17 because acos(1) != 0. |
4f6a2eb2 |
36 | # Resolved in 970211 Beta |
ff68c719 |
37 | # lib/io_udp.t test hangs because of a bug in getsockname(). |
38 | # Fixed in latest BETA socket3r.lib |
39 | # If there is a softlink in your path, Findbin will fail. |
4f6a2eb2 |
40 | # This is a documented feature of perl's getpwd(). |
ff68c719 |
41 | # There is currently no support for dynamically linked |
42 | # libraries. |
4f6a2eb2 |
43 | # op/magic.t failure due to a feature of QNX which rewrites script |
44 | # names before they are executed. I think you'll find that if |
45 | # you cd `fullpath -t` before doing the make, the test will pass. |

47 | # At present, all QNX systems are equivalent architectures, |
48 | # so it might be reasonable to call archname=qnx rather than |
49 | # making an unnecessary distinction between AT-qnx and PCI-qnx, |
50 | # for example. |
