12 | # perl-5.10.0-tobe compiles with Watcom C 10.6 |
13 | # and QNX 4.25 patch G w/TCPSDK installed | |
14 | # Some tests still fail, mostly to do with dynamic/static | |
dca46f05 | 15 | # or unsupported features in QNX. |

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

42 | # Outstanding Issues for QNX4: |
43 | # There is no support for dynamically linked libraries in | |
44 | # QNX4. | |

46 | # If you wish to compile with the Socket extension, you need | |
47 | # to have the TCP/IP toolkit, and you need to make sure that | |
48 | # -lsocket locates the correct copy of socket3r.lib. Beware | |
49 | # that the Watcom compiler ships with a stub version of | |
50 | # socket3r.lib which has very little functionality. Also | |
51 | # beware the order in which wlink searches directories for | |
52 | # libraries. You may have /usr/lib/socket3r.lib pointing to | |
53 | # the correct library, but wlink may pick up | |
54 | # /usr/watcom/10.6/usr/lib/socket3r.lib instead. Make sure | |
55 | # they both point to the correct library, that is, | |
56 | # /usr/tcptk/current/usr/lib/socket3r.lib. | |
af23fe4d | 57 | # |
2a6dc374 | 58 | # dist/Cwd/Cwd.t will complain if `pwd` and cwd don't give |
af23fe4d NA |
59 | # the same results. cwd calls `fullpath -t`, so if you |
60 | # cd `fullpath -t` before running the test, it will | |
61 | # pass. | |
62 | # | |
63 | # lib/File/Find/taint.t will complain if '.' is in your | |
64 | # PATH. The PATH test is triggered because cwd calls | |
65 | # `fullpath -t`. | |
66 | # | |
a181ddb7 NA |
67 | # ext/IO/lib/IO/t/io_sock.t: Subtest 14 is skipped due to |
68 | # the fact that the functionality to read back the non-blocking | |
69 | # status of a socket is not implemented in QNX's TCP/IP. This | |
70 | # has been reported to QNX and it may work with later versions | |
71 | # of TCP/IP. | |
af23fe4d NA |
72 | # |
73 | # Older issues: | |
74 | # lib/posix.t test failed on test 17 because acos(1) != 0. | |
4f6a2eb2 | 75 | # Resolved in 970211 Beta |
ff68c719 | 76 | # lib/io_udp.t test hangs because of a bug in getsockname(). |
77 | # Fixed in latest BETA socket3r.lib | |

ecd6d377 | 79 | # Outstanding Issues for QNX6: |
3ed0a8dd | 80 | # The following tests are still failing as of 5.7.3: |
ecd6d377 NA |
81 | # |
82 | # op/sprintf.........................FAILED at test 91 | |
3ed0a8dd NA |
83 | # lib/Benchmark......................FAILED at test 26 |
84 | # | |
85 | # This is due to a bug in the C library's printf routine. | |
86 | # printf("'%e'", 0. ) produces '0.000000e+0', but ANSI requires | |
87 | # '0.000000e+00'. QNX has acknowledged the bug and it should be | |
88 | # fixed in 6.2.0. | |
