Well, personally I'd recommend just building it with what you've got and
worry about the visibility bug if you ever actually encounter the
crash :-)

Where is the patch or src.rpm?

As you recomended,I am compiling gcc 4.3.1 on my machine which
will keep me busy for a while until I get back.

In this way, I will have someone to bug when 4.3.1 does not work well :P.

Those actual warnings are basically spurious, ignore them. 

But, I know that your particular compiler, given as it is equivalent to
the RHEL-5 gcc, actually probably *does* has a bug with visibility which
IIRC may cause OOo to crash when it loads some old .sdw files, the
workaround it to disable visibility or to apply the
openoffice.org.2.0.3-dangerousvisibility.patch patch found in the
RHEL-4/CentOS openoffice.org src.rpm. It's pretty uncommon, but it can
happen. If you are just building OOo for hacking around with, then I
wouldn't bother changing your compiler for it.

I don't think I've met a compiler yet that doesn't have *some* bug that
has affected openoffice.org in some way:-), but I'm pretty happy with
gcc 4.3.0/4.3.1 whose only known bug that has affected me is with
-fasynchronous-unwind-tables on i386 which isn't enabled by default on
that architecture anyway.

It is 4.1.2 as I said in the OP.

Should I upgrade my gcc?
What version of gcc is recommended for building OOo 3?

Thanks for you answer!!!

Basically "yes", it is safe to ignore the warning. What is your compiler
version, i.e. gcc -v. Some various vendors gcc versions between about >
4.1.X and < 4.3.0 had various slightly different experimental visibility
features in them. One of them was sort of an attempt (IIUC) to make
visibility markup a sort of C++ language extension and so giving these
sort of warnings when (what was felt to be) logical inconsistencies in
markup was detected

Now in gcc 4.3.0 things have settled down visibility-wise and such a
compiler shouldn't warn about this.

*some* gcc variant's visibility stuff doesn't always work right, and can
cause horrific hard-to-find crashes. But I think that if your compiler
gets past the configure tests for common visibility brokenness then you
should be safe regardless of those warnings.

Hi all,

When I compile DEV300_m29 with dmake, I get the following *warning*:

/home/vuhung/public_html/foss/src/DEV300_m29/solver/300/
unxlngi6.pro/inc/com/sun/star/uno/Any.hxx:268:
warning: lowering visibility of 'sal_Bool
com::sun::star::uno::operator==(const com::sun::star::uno::Any&, const
C&) [with C = bool]' to match its type

Is that safe to ignore the warning?
I am just curious  because the template Any seems to be used quite
office, and the warning looks annoying.
