4 # These hints were written for QNX4, but are in the process
5 # of being extended to encompass Neutrino as well.
7 # As of perl5.004_04, all tests pass under:
9 # Watcom 10.6 with Beta/970211.wcc.update.tar.F
10 # socket3r.lib Nov21 1996.
11 # perl-5.6.1 runs well on QNX4 with a few known test failures
12 # perl-5.6.0 ships with QNX RTP (Neutrino) but the build is
13 # not yet straightforward.
15 # As with many unix ports, this one depends on a few "standard"
16 # unix utilities which are not necessarily standard for QNX4.
18 # /bin/sh This is used heavily by Configure and then by
19 # perl itself. QNX4's version is fine, but Configure
20 # will choke on the 16-bit version, so if you are
21 # running QNX 4.22, link /bin/sh to /bin32/ksh
22 # ar This is the standard unix library builder.
23 # We use wlib. With Watcom 10.6, when wlib is
24 # linked as "ar", it behaves like ar and all is
25 # fine. Under 9.5, a cover is required. One is
27 # nm This is used (optionally) by configure to list
28 # the contents of libraries. I will generate
29 # a cover function on the fly in the UU directory.
30 # cpp Configure and perl need a way to invoke a C
31 # preprocessor. I have created a simple cover
32 # for cc which does the right thing. Without this,
33 # Configure will create its own wrapper which works,
34 # but it doesn't handle some of the command line arguments
35 # that perl will throw at it.
36 # make You really need GNU make to compile this. GNU make
37 # ships by default with QNX 4.23, but you can get it
38 # from quics for earlier versions.
39 #----------------------------------------------------------------
40 # Outstanding Issues for QNX4:
41 # There is no support for dynamically linked libraries in
44 # ext/Cwd/Cwd.t will complain if `pwd` and cwd don't give
45 # the same results. cwd calls `fullpath -t`, so if you
46 # cd `fullpath -t` before running the test, it will
49 # lib/File/Find/taint.t will complain if '.' is in your
50 # PATH. The PATH test is triggered because cwd calls
53 # ext/IO/lib/IO/t/io_sock.t: Subtest 14 is skipped due to
54 # the fact that the functionality to read back the non-blocking
55 # status of a socket is not implemented in QNX's TCP/IP. This
56 # has been reported to QNX and it may work with later versions
60 # lib/posix.t test failed on test 17 because acos(1) != 0.
61 # Resolved in 970211 Beta
62 # lib/io_udp.t test hangs because of a bug in getsockname().
63 # Fixed in latest BETA socket3r.lib

78 # At present, all QNX4 systems are equivalent architectures,

80 # making an unnecessary distinction between AT-qnx and PCI-qnx,

96 # don't work reliably:

104 # (Basically, the same race conditions apply, but assuming
105 # the scripts are located in a secure directory, the methods
106 # for exploiting the race condition are defeated because

157 I don't see an 'ar', so I'm guessing you are running
158 Watcom 9.5 or earlier. You may want to install the ar
159 cover found in the qnx subdirectory of this distribution.
160 It might reasonably be placed in /usr/local/bin.

171 Creating a quick-and-dirty nm cover for Configure to use:
174 cat >./UU/nm <<-'EOF'
177 #%C <lib> [<lib> ...]
178 # Designed to mimic Unix's nm utility to list
179 # defined symbols in a library

196 I found a cpp at $cppstdin and will assume it is a good
197 thing to use. If this proves to be false, there is a
198 thin cover for cpp in the qnx subdirectory of this
199 distribution which you could move into your path.
205 There is a cpp cover in the qnx subdirectory of this
206 distribution which works a little better than the
207 Configure default. You may wish to copy it to
208 /usr/local/bin or some other suitable location.
