Description David Woodhouse 2006-05-02 17:06:02 UTC

After installing the current version of gnash
(http://www.gnu.org/software/gnash/) I find it fails as follows:

"WARNING: No xEmbed support in this Mozilla version!"

Comment 1 David Woodhouse 2006-05-03 10:28:01 UTC

The sample code at
http://www.mozilla.org/projects/plugins/xembed-plugin-extension.html suggests
that you should use this code to detect XEmbed...

    PRBool supportsXEmbed = PR_FALSE;

    err = CallNPN_GetValueProc(gNetscapeFuncs.getvalue, NULL,
                               NPNVSupportsXEmbedBool,
                               (void *)&supportsXEmbed);

    if (err != NPERR_NO_ERROR || supportsXEmbed != PR_TRUE)
        return NPERR_INCOMPATIBLE_VERSION_ERROR;

This doesn't seem to work though. PRBool seems to be an int -- its size is 4
bytes. The CallNPN_GetValueProc() call sets only the first byte and leaves the
others untouched. So on a big-endian machine, supportsXEmbed gets set to
0x01000000, which != PR_TRUE.

Is this a bug in the documentation, or in our firefox?

Comment 2 Matěj Cepl 2007-07-18 17:30:03 UTC

Fedora Core 5 is no longer supported, could you please reproduce this with the
updated version of the currently supported distribution (Fedora Core 6, or
Fedora 7, or Rawhide)? If this issue turns out to still be reproducible, please
let us know in this bug report.  If after a month's time we have not heard back
from you, we will have to close this bug as CANTFIX.

Setting status to NEEDINFO, and awaiting information from the reporter.

Thanks in advance.

Comment 3 Matěj Cepl 2007-08-28 14:44:35 UTC

We haven't got any reply to the last question about reproducability of the bug
with Fedora Core 6, Fedora 7, or Fedora devel. Mass closing this bug, so if you
have new information that would help us fix this bug, please reopen it with the
additional information.
