# QNX hints
#
-# As of perl5.004_04, all tests pass under:
-# QNX 4.23A
+# 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
#
-# As with many unix ports, this one depends on a few "standard"
-# unix utilities which are not necessarily standard for QNX.
+# 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. QNX's version is fine, but Configure
+# 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.
# 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.
+# 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
-# There is currently no support for dynamically linked
-# libraries.
+#----------------------------------------------------------------
+# 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.
