2 | # QNX hints | |

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

3ed0a8dd | 7 | # perl-5.7.3 passes all tests under QNX4.24G |
4f6a2eb2 TB |
8 | # Watcom 10.6 with Beta/970211.wcc.update.tar.F |
9 | # socket3r.lib Nov21 1996. | |
3ed0a8dd | 10 | # perl-5.7.3 fails 2 known tests under QNX6.1.0 |
ff68c719 | 11 | # |
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. | |

41 | # If you wish to compile with the Socket extension, you need | |
42 | # to have the TCP/IP toolkit, and you need to make sure that | |
43 | # -lsocket locates the correct copy of socket3r.lib. Beware | |
44 | # that the Watcom compiler ships with a stub version of | |
45 | # socket3r.lib which has very little functionality. Also | |
46 | # beware the order in which wlink searches directories for | |
47 | # libraries. You may have /usr/lib/socket3r.lib pointing to | |
48 | # the correct library, but wlink may pick up | |
49 | # /usr/watcom/10.6/usr/lib/socket3r.lib instead. Make sure | |
50 | # they both point to the correct library, that is, | |
51 | # /usr/tcptk/current/usr/lib/socket3r.lib. | |

52 | # |
53 | # ext/Cwd/Cwd.t will complain if `pwd` and cwd don't give | |
54 | # the same results. cwd calls `fullpath -t`, so if you | |
55 | # cd `fullpath -t` before running the test, it will | |
56 | # pass. | |
57 | # | |
58 | # lib/File/Find/taint.t will complain if '.' is in your | |
59 | # PATH. The PATH test is triggered because cwd calls | |
60 | # `fullpath -t`. | |
61 | # | |
a181ddb7 NA |
62 | # ext/IO/lib/IO/t/io_sock.t: Subtest 14 is skipped due to |
63 | # the fact that the functionality to read back the non-blocking | |
64 | # status of a socket is not implemented in QNX's TCP/IP. This | |
65 | # has been reported to QNX and it may work with later versions | |
66 | # of TCP/IP. | |

67 | # |
68 | # Older issues: | |
69 | # lib/posix.t test failed on test 17 because acos(1) != 0. | |
4f6a2eb2 | 70 | # Resolved in 970211 Beta |
ff68c719 | 71 | # lib/io_udp.t test hangs because of a bug in getsockname(). |
72 | # Fixed in latest BETA socket3r.lib | |

3ed0a8dd | 75 | # The following tests are still failing as of 5.7.3: |

76 | # |
77 | # op/sprintf.........................FAILED at test 91 | |
3ed0a8dd NA |
78 | # lib/Benchmark......................FAILED at test 26 |
79 | # | |
80 | # This is due to a bug in the C library's printf routine. | |
81 | # printf("'%e'", 0. ) produces '0.000000e+0', but ANSI requires | |
82 | # '0.000000e+00'. QNX has acknowledged the bug and it should be | |
83 | # fixed in 6.2.0. | |
