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 it's 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. |
