7 README.qnx - Perl version 5 on QNX
11 As of perl5.7.2 all tests pass under:
14 Watcom 10.6 with Beta/970211.wcc.update.tar.F
15 socket3r.lib Nov21 1996.
17 Some tests may complain under known circumstances. See
18 below and hints/qnx.sh for more information.
20 Under QNX 6.1.0 there are still a few tests which fail.
21 See below and hints/qnx.sh for more information.
23 =head2 Required Software for Compiling Perl on QNX4
25 As with many unix ports, this one depends on a few "standard"
26 unix utilities which are not necessarily standard for QNX4.
32 This is used heavily by Configure and then by
33 perl itself. QNX4's version is fine, but Configure
34 will choke on the 16-bit version, so if you are
35 running QNX 4.22, link /bin/sh to /bin32/ksh
39 This is the standard unix library builder.
40 We use wlib. With Watcom 10.6, when wlib is
41 linked as "ar", it behaves like ar and all is
42 fine. Under 9.5, a cover is required. One is
47 This is used (optionally) by configure to list
48 the contents of libraries. I will generate
49 a cover function on the fly in the UU directory.
53 Configure and perl need a way to invoke a C
54 preprocessor. I have created a simple cover
55 for cc which does the right thing. Without this,
56 Configure will create its own wrapper which works,
57 but it doesn't handle some of the command line arguments
58 that perl will throw at it.
62 You really need GNU make to compile this. GNU make
63 ships by default with QNX 4.23, but you can get it
64 from quics for earlier versions.
68 =head2 Outstanding Issues with Perl on QNX4
70 There is no support for dynamically linked libraries in QNX4.
72 The following tests may report errors under QNX4:
74 ext/Cwd/Cwd.t will complain if `pwd` and cwd don't give
75 the same results. cwd calls `fullpath -t`, so if you
76 cd `fullpath -t` before running the test, it will
79 lib/File/Find/taint.t will complain if '.' is in your
80 PATH. The PATH test is triggered because cwd calls
83 ext/IO/lib/IO/t/io_sock.t: Subtest 14 is skipped due to
84 the fact that the functionality to read back the non-blocking
85 status of a socket is not implemented in QNX's TCP/IP. This
86 has been reported to QNX and it may work with later versions
89 =head2 QNX auxiliary files
91 The files in the "qnx" directory are:
97 A script that emulates the standard unix archive (aka library)
98 utility. Under Watcom 10.6, ar is linked to wlib and provides the
99 expected interface. With Watcom 9.5, a cover function is
100 required. This one is fairly crude but has proved adequate for
101 compiling perl. A more thorough version is available at:
103 http://www.fdma.com/pub/qnx/porting/ar
107 A script that provides C preprocessing functionality. Configure can
108 generate a similar cover, but it doesn't handle all the command-line
109 options that perl throws at it. This might be reasonably placed in
