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.
Some tests may complain under known circumstances. See below and hints/qnx.sh for more information.
Under QNX 6.1.0 there are still a few tests which fail. See below and hints/qnx.sh for more information.
As with many unix ports, this one depends on a few "standard" unix utilities which are not necessarily standard for 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 `fullpath -t`.
ext/IO/lib/IO/t/io_sock.t: Subtest 14 is 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.
The files in the "qnx" directory are:
The following tests are still failing for Perl 5.7.3 under QNX 6.1.0:
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 and it should be fixed in 6.2.0.
