2# QNX hints
3#
4f6a2eb2 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.
ff68c719 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.
4f6a2eb2 36# Resolved in 970211 Beta
ff68c719 37# lib/io_udp.t test hangs because of a bug in getsockname().
38# Fixed in latest BETA socket3r.lib
ff68c719 39# There is currently no support for dynamically linked
40# libraries.

7fbf1995 55# At present, all QNX systems are equivalent architectures,
56# so it is reasonable to call archname=x86-qnx rather than
57# making an unnecessary distinction between AT-qnx and PCI-qnx,
58# for example.

4f6a2eb2 71# setuid scripts are secure under QNX.
72# (Basically, the same race conditions apply, but assuming

74# for exploiting the race condition are defeated because
75# the loader expands the script name fully before executing
76# the interpreter.)

ff68c719 125 I don't see an 'ar', so I'm guessing you are running

128 It might reasonably be placed in /usr/local/bin.
