5 | # more help. The QNX6 hints are located toward the bottom. |

10 | # perl-5.7.2 fails 4 known tests under QNX6.1.0 |
ff68c719 |

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

37 | # Outstanding Issues for QNX4: |
38 | # There is no support for dynamically linked libraries in |
39 | # QNX4. |
40 | # |
41 | # ext/Cwd/Cwd.t will complain if `pwd` and cwd don't give |
42 | # the same results. cwd calls `fullpath -t`, so if you |
43 | # cd `fullpath -t` before running the test, it will |
44 | # pass. |
45 | # |
46 | # lib/File/Find/taint.t will complain if '.' is in your |
47 | # PATH. The PATH test is triggered because cwd calls |
48 | # `fullpath -t`. |
49 | # |
a181ddb7 |
50 | # ext/IO/lib/IO/t/io_sock.t: Subtest 14 is skipped due to |
51 | # the fact that the functionality to read back the non-blocking |
52 | # status of a socket is not implemented in QNX's TCP/IP. This |
53 | # has been reported to QNX and it may work with later versions |
54 | # of TCP/IP. |
af23fe4d |
55 | # |
56 | # Older issues: |
57 | # lib/posix.t test failed on test 17 because acos(1) != 0. |
4f6a2eb2 |
58 | # Resolved in 970211 Beta |
ff68c719 |
59 | # lib/io_udp.t test hangs because of a bug in getsockname(). |
60 | # Fixed in latest BETA socket3r.lib |
