     README.qnx - Perl version 5 on QNX

     As of perl5.7.2 all tests pass under:

       QNX 4.24G
       Watcom 10.6 with Beta/970211.wcc.update.tar.F
       socket3r.lib Nov21 1996.

     As of perl5.8.1 there is at least one test still failing.

     Some tests may complain under known circumstances.

     See below and hints/ for more information.

     Under QNX 6.2.0 there are still a few tests which fail.  See
     below and hints/ for more information.

  Required Software for Compiling Perl on QNX4
     As with many unix ports, this one depends on a few
     "standard" unix utilities which are not necessarily standard
     for QNX4.

         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.

         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 with Perl on QNX4
     There is no support for dynamically linked libraries in

     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,

     The following tests may report errors under QNX4:

     cpan/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: Subtests 14 and 22 are 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.

     t/io/tell.t: Subtest 27 is failing. We are still

  QNX auxiliary files
     The files in the "qnx" directory are:

         A script that emulates the standard unix archive (aka
         library) utility.  Under Watcom 10.6, ar is linked to
         wlib and provides the expected interface. With Watcom
         9.5, a cover function is required. This one is fairly
         crude but has proved adequate for compiling perl.

         A script that provides C preprocessing functionality.
         Configure can generate a similar cover, but it doesn't
         handle all the command-line options that perl throws at
         it. This might be reasonably placed in /usr/local/bin.

  Outstanding issues with perl under QNX6
     The following tests are still failing for Perl 5.8.1 under

perl v5.12.5         Last change: 2012-11-03                    2

     QNX 6.2.0:

       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.
