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 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. +# +# ext/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'.
