hello world,

I'm looking for predefined constant(s) which would give
me the version and release numbers of HP-UX during compiler runs,
i.e. sth universal and unique like "__hpux" I could put into an #ifdef.

As a workaround I've tried to use "-D..." settings during make & compile,
but unfortunately HP's "uname" implementation is braindead (IMHO).
So when I'm running under 11.00
`uname -v` gives me B.11.00 (would have expected just "11")
and
`uname -r` gives me some nonsense (would have expected just "00").

I know that e.g. AIX predefines -D_AIX41 for everything higher than Version 4.1
and -D_AIX43 for everything higher than Version 4.3, and so forth.
Is there an equivalent on HP-UX ?

The HP-UX user space architect doesn't want this. He says you are
suppose to use the feature test macros, not OS versions.

The proper way to use uname(1) is:
$ echo $(uname -r | sed -e 's/..//' -e 's/\.//')

OK, then how do I test (on the #ifdef level) the existence of
e.g. dlopen() and friends, w/o including dlfcn.h ?
These do not exist in earlier versions ( 9, 10.x ?).

OK, I'll give it a try.
Meanwhile, I have found a section in the FAQ,
with a test on certain flags defined in <sys/privgrp.h>.
Is this safe enough ? Looks a bit dodgy to me.

thanks anyway.

For gcc on just about every platform I compile upon, i create a script
I call predefined, which takes a single argument, the compiler you use,
and it will show you what is predefined on that particular platform:

predefined gcc

The file contains the following single line:

$1 -E -dM - < /dev/null

Unfortunately this is not quite what I was looking for.
Apart from the fact that I use native compilers wherever possible,
your example gives a lot of #defines, but not the OS version.
And it does not give me the opportunity to put a simple
#if defined(__hpux) && ( OSVERSION < 1000 )
into the source code.
