| 2 | # QNX hints |
| 3 | # |
| 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. |
| 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, |
| 27 | # Configure will create its own wrapper which works, |
| 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. |
| 36 | # Resolved in 970211 Beta |
| 37 | # lib/io_udp.t test hangs because of a bug in getsockname(). |
| 38 | # Fixed in latest BETA socket3r.lib |
| 39 | # There is currently no support for dynamically linked |
| 40 | # libraries. |
