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, | |
022735b4 | 27 | # Configure will create its own wrapper which works, |
ff68c719 | 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 | |
ff68c719 | 39 | # There is currently no support for dynamically linked |
40 | # libraries. | |

55 | # At present, all QNX systems are equivalent architectures, |

58 | # for example. | |
