The remaining +# failures have been identified as bugs in the Watcom libraries +# which I hope will be fixed in the near future. +# +# 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. +# Watcom promises to fix this in next release. +# lib/io_udp.t test hangs because of a bug in getsockname(). +# Fixed in latest BETA socket3r.lib +# If there is a softlink in your path, Findbin will fail. +# This is a documented feature of getpwd(). +# There is currently no support for dynamically linked +# libraries. +#---------------------------------------------------------------- +# At present, all QNX systems are equivalent architectures, +# so it might be reasonable to call archname=qnx rather than +# making an unnecessary distinction between AT-qnx and PCI-qnx, +# for example. +#---------------------------------------------------------------- +# These hints were submitted by: +# Norton T.
