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:
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
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
perl v5.12.5 Last change: 2012-11-03 2
Perl Programmers Reference Guide PERLQNX(1)
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.
