# QNX hints
#
-# These hints were written for QNX4, but are in the process
-# of being extended to encompass Neutrino as well.
+# Most of the hints in this file are for QNX4, which needed
+# more help. The QNX6 hints are located toward the bottom.
#
-# As of perl5.004_04, all tests pass under:
-# QNX 4.23A
+# 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-5.6.1 runs well on QNX4 with a few known test failures
-# perl-5.6.0 ships with QNX RTP (Neutrino) but the build is
-# not yet straightforward.
+# perl-5.7.3 fails 2 known tests under QNX6.1.0
#
-# As with many unix ports, this one depends on a few "standard"
+# 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
# 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.
#
-# ext/Cwd/Cwd.t will complain if `pwd` and cwd don't give
+# 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/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.
+#

# Norton T. Allen
# Harvard University Atmospheric Research Project
# making an unnecessary distinction between AT-qnx and PCI-qnx,
# for example. I will use uname's architecture for Neutrino.
