PERLQNX(1)             Perl Programmers Reference Guide             PERLQNX(1)



NAME
       README.qnx - Perl version 5 on QNX

DESCRIPTION
       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/qnx.sh for more information.

       Under QNX 6.2.0 there are still a few tests which fail.  See below and hints/qnx.sh 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.

       /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 with Perl on 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.

       The following tests may report errors under QNX4:

       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 'full-
       path -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 investigating.

       QNX auxiliary files

       The files in the "qnx" directory are:

       qnx/ar
           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.

       qnx/cpp
           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 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.
