Are +u and +z still valid options in aCC version A.05.50?

[Charles_126]

I can find no reference to these options in the aCC man page nor are they in the Online Documentation (http://docs.hp.com/hpux/onlinedocs/4310/options.htm).

Yet, they are referred to in the "Programmer's Guide for Java 2, JNI section as being necessary.

I would prefer not to use them because it would change the build scripts we have been using.

Thanks for your help.

The +u4 option is still valid in aCC A.05.55.
It continues to appear in "man aCC".

The +z option is really always on for the IPF versions of aCC. It requests position-independent code for use in shared libraries. aCC does that by default. It ignores the option.

Thanks for the +z info. That helps.

I looked in the aCC version A.05.550 man page yet again for the +unum option and still cannot find it. I can find +ub and +uc options but these cannot possibly be providing the same functionality as +unum. And it's definitely not in the Online Documentation.

Are there different versions of the documentation perhaps? Can you point me to the man page number that you find it at?

I find it in "man aCC" using the /opt/aCC/share/man/man1.Z/aCC.1 manual page.
It is just before the +ub option.
I will attach the output of "man aCC | col -b".

+unum Allow pointers to access non-natively aligned data.
This option alters the way that the compiler accesses
dereferenced data. Use of this option may reduce the
efficiency of generated code. (See also #pragma pack
in the HP aC++ Online Programmer's Guide for a more
efficient method.)
1 Assume single byte alignment. Dereferences are
performed with a series of single-byte loads
and stores.
2 Dereferences are performed with a series of
two-byte loads and stores.
4 Dereferences are performed with a series of
four-byte loads and stores.

Thanks Mike. We are definitely looking at different man pages as the one I am using has the +tls option prior to the +ub option.

The man pages I am using have a header on each page that looks like this:
Hewlett-Packard Company - 12 - aC++/C Version A.05.50

As well when I enter:
aCC -V
the result is:
aCC: HP aC++/ANSI C B3910B A.05.50 [May 15 2003]

Are these the same versions that you have?

OK, I just noticed you had attached the entire man page. I looked at it and it *is* different from the man page we have here but it is for the same version.

Weird.

Thanks a lot for your help Mike.
