[Re-posting to fix the subject, which I had copied from an earlier
message...  Very sorry for the mess.]

Hello -

I'm using Ardour 2.7.1 on Fedora 8 32-bit (ardour-2.7.1-0.1.fc8.ccrma,
to be precise), running on a Core2 Duo machine.  Among the messages I
see when I launch ardour2 is this:

>WARNING: Your system contains a suspect libglib-2.0. Your version might be built
>         to use mutex locking atomic operations. This is a fallback solution to
>         a more robust hardware supported atomicity. It might cause reduced

Looks as though this is coming from one of the wrappers:
/usr/libexec/ardour2.  The library it seems to be complaining about
(from the output of ldd) is

    libglib-2.0.so.0 => /lib/libglib-2.0.so.0

which on this machine comes from the package


If I'm reading it right, it complains when the size of the symbol
"g_atomic_int_add" > 32, and mine is 105.

I've been ignoring the message, and as far as I can tell, Ardour is not
having any problems that seem obviously related to this.  Google shed no
light (or I just didn't ask nicely).  If it isn't a real issue, I'm OK
with continuing to ignore it.  :)  Just wanted to make sure I didn't
mess up the installation somehow.  Oh, and yum thinks the system is up
to date.
