# QNX hints
|
|
#
|
|
# Most of the hints in this file are for QNX4, which needed
|
|
# more help. The QNX6 hints are located toward the bottom.
|
|
#
|
|
# perl-5.7.3 passes all tests under QNX4.24G
|
|
# Watcom 10.6 with Beta/970211.wcc.update.tar.F
|
|
# socket3r.lib Nov21 1996.
|
|
# perl-5.7.3 fails 2 known tests under QNX6.1.0
|
|
#
|
|
# perl-5.10.0-tobe compiles with Watcom C 10.6
|
|
# and QNX 4.25 patch G w/TCPSDK installed
|
|
# Some tests still fail, mostly to do with dynamic/static
|
|
# or unsupported features in QNX.
|
|
#
|
|
## As with many unix ports, this one depends on a few "standard"
|
|
# unix utilities which are not necessarily standard for QNX4.
|
|
#
|
|
# /bin/sh This is used heavily by Configure and then by
|
|
# perl itself. QNX4'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 its 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 for QNX4:
|
|
# There is no support for dynamically linked libraries in
|
|
# QNX4.
|
|
#
|
|
# If you wish to compile with the Socket extension, you need
|
|
# to have the TCP/IP toolkit, and you need to make sure that
|
|
# -lsocket locates the correct copy of socket3r.lib. Beware
|
|
# that the Watcom compiler ships with a stub version of
|
|
# socket3r.lib which has very little functionality. Also
|
|
# beware the order in which wlink searches directories for
|
|
# libraries. You may have /usr/lib/socket3r.lib pointing to
|
|
# the correct library, but wlink may pick up
|
|
# /usr/watcom/10.6/usr/lib/socket3r.lib instead. Make sure
|
|
# they both point to the correct library, that is,
|
|
# /usr/tcptk/current/usr/lib/socket3r.lib.
|
|
#
|
|
# dist/Cwd/Cwd.t will complain if `pwd` and cwd don't give
|
|
# the same results. cwd calls `fullpath -t`, so if you
|
|
# cd `fullpath -t` before running the test, it will
|
|
# pass.
|
|
#
|
|
# lib/File/Find/taint.t will complain if '.' is in your
|
|
# PATH. The PATH test is triggered because cwd calls
|
|
# `fullpath -t`.
|
|
#
|
|
# ext/IO/lib/IO/t/io_sock.t: Subtest 14 is skipped due to
|
|
# the fact that the functionality to read back the non-blocking
|
|
# status of a socket is not implemented in QNX's TCP/IP. This
|
|
# has been reported to QNX and it may work with later versions
|
|
# of TCP/IP.
|
|
#
|
|
# Older issues:
|
|
# lib/posix.t test failed 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
|
|
#----------------------------------------------------------------
|
|
# Outstanding Issues for QNX6:
|
|
# The following tests are still failing as of 5.7.3:
|
|
#
|
|
# op/sprintf.........................FAILED at test 91
|
|
# lib/Benchmark......................FAILED at test 26
|
|
#
|
|
# This is due to a bug in the C library's printf routine.
|
|
# printf("'%e'", 0. ) produces '0.000000e+0', but ANSI requires
|
|
# '0.000000e+00'. QNX has acknowledged the bug and it should be
|
|
# fixed in 6.2.0.
