# QNX hints
|

#
|

|
|
# As of perl5.004_04, all tests pass under:
|
||
|
|
# QNX 4.23A
|
||
|
|
# Watcom 10.6 with Beta/970211.wcc.update.tar.F
|
||
|
|
# socket3r.lib Nov21 1996.
|
||
|
|
#
|
||
|
|
# As with many unix ports, this one depends on a few "standard"
|
||
|
|
# unix utilities which are not necessarily standard for QNX.
|
||
|
|
#
|
||
|
|
# /bin/sh This is used heavily by Configure and then by
|
||
|
|
# perl itself. QNX's version is fine, but Configure
|
||
|
|
# will choke on the 16-bit version, so if you are
|
||
|
|
# running QNX 4.22, link /bin/sh to /bin32/ksh
|
||
|
|
# ar This is the standard unix library builder.
|
||
|
|
# We use wlib. With Watcom 10.6, when wlib is
|
||
|
|
# linked as "ar", it behaves like ar and all is
|
||
|
|
# fine. Under 9.5, a cover is required. One is
|
||
|
|
# included in ../qnx
|
||
|
|
# nm This is used (optionally) by configure to list
|
||
|
|
# the contents of libraries. I will generate
|
||
|
|
# a cover function on the fly in the UU directory.
|
||
|
|
# cpp Configure and perl need a way to invoke a C
|
||
|
|
# preprocessor. I have created a simple cover
|
||
|
|
# for cc which does the right thing. Without this,
|
||
|
|
# Configure will create it's own wrapper which works,
|
||
|
|
# but it doesn't handle some of the command line arguments
|
||
|
|
# that perl will throw at it.
|
||
|
|
# make You really need GNU make to compile this. GNU make
|
||
|
|
# ships by default with QNX 4.23, but you can get it
|
||
|
|
# from quics for earlier versions.

# Outstanding Issues:
|

|
# lib/posix.t test fails on test 17 because acos(1) != 0.
|

|
|
# Resolved in 970211 Beta
|
||
|
|
# lib/io_udp.t test hangs because of a bug in getsockname().
|
||
|
|
# Fixed in latest BETA socket3r.lib
|
||
|
|
# There is currently no support for dynamically linked
