| 3 | # |
| 4 | # Most of the hints in this file are for QNX4, which needed |
| 5 | # more help. The QNX6 hints are located toward the bottom. |
| 6 | # |
| 7 | # perl-5.7.3 passes all tests under QNX4.24G |
| 8 | # Watcom 10.6 with Beta/970211.wcc.update.tar.F |
| 9 | # socket3r.lib Nov21 1996. |
| 10 | # perl-5.7.3 fails 2 known tests under QNX6.1.0 |
| 11 | # |
| 12 | # As with many unix ports, this one depends on a few "standard" |
| 13 | # unix utilities which are not necessarily standard for QNX4. |
| 14 | # |
| 15 | # /bin/sh This is used heavily by Configure and then by |
| 16 | # perl itself. QNX4's version is fine, but Configure |
| 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, |
| 30 | # Configure will create its own wrapper which works, |
| 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. |
| 36 | #---------------------------------------------------------------- |
| 37 | # Outstanding Issues for QNX4: |
| 38 | # There is no support for dynamically linked libraries in |
| 39 | # QNX4. |
| 40 | # |
| 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 | # |
| 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. |
| 70 | # Resolved in 970211 Beta |
| 71 | # lib/io_udp.t test hangs because of a bug in getsockname(). |
| 72 | # Fixed in latest BETA socket3r.lib |
| 73 | #---------------------------------------------------------------- |
| 74 | # Outstanding Issues for QNX6: |
| 75 | # The following tests are still failing as of 5.7.3: |
| 76 | # |
| 77 | # op/sprintf.........................FAILED at test 91 |
| 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. |
