Plugins in the plugins directory don't get detected. I seem to be the only one
experiencing this failure, but I still do, and have for the past month or so
(downloading new builds everyday.)

my mozilla path is /home/oli/bin/mozilla/mozilla

Here are the details:
I install two plugins and one component.
Plugin 1: Flash Player 5r47, package flash_linux.tar.gz from macromedia
Plugin 2: Java, package jre.xpi from ftp.netscape.com in ns6 directory
Component 1: Spellcheker, package spellcheck.xpi from ftp.netscape.com in ns6 dir

Installation:
--Plugin 1: copy 'ShockwaveFlash.class' && 'libflashplayer.so' in
mozilla/plugins directory.
--Plugin 2: File->Open File... jre.xpi.
--Component 1: File->Open File... spellcheck.xpi

... close and restart mozilla ...

Status:
--Plugin 1: not showing as detected in "about:plugins". Failed.
--Plugin 2: not showing as detected in "about:plugins". Failed.
--Component 1: Spellcheck icon appears in Mail Message windows. Pass.

Conclusion:
Plugins in the mozilla/plugins directories don't get detected. However, it is
not a problem with xpi packages since components like Spellcheck install
properly, and that flash still doesn't.

A friend and I just ran into this on a clean RedHat-7 install, nightly from
yesterday (2001-03-18).

Worked on my RH-7, didn't work on his.

To fix, we installed the libstdc++-compat libraries (I don't know if this is an
issue on Debian), but also the XFree86-devel libraries.

Specifically, it seems like if you don't install the devel RPM on RH, you don't
get libX11.so, libXt.so, etc. etc.  All you get is libX11.so.6, but the plugins
require the .so's not the .so.6's.  This is a guess; after getting it working my
friend didn't want to experiment. ;)

I hope I'm being clear; I'll reiterate.

It seems like the problem is one or both of:
1. Incompatible C++ library (possibly a RedHat-7-only problem due to gcc
``2.96'', but you do say you are running unstable)
2. Missing X11 symbolic links to provide version-independent library names

Our steps to fix:
1. Install libstdc++-compat RPM
2. Install XFree86-devel RPM

This fixed both the moz nightly and NS6.01. 

Can you two verify?


If this is the case, it is not a Mozilla issue -- it's a platform packaging
problem.  However, the best solution would be for the Mozilla/Netscape installer
to look for this and fix it, or at least report the problem?

These are the debian packages that I've installed.
-xlib6g-dev (pseudo-package depending on the later two)
-xlibs-dev
-libxaw-dev

The plugins where installed before I installed the lib packages, and weren't
working. After installing the lib packages, I restarted Mozilla and the plugins
were working.

I guess Steven was right. Maybe something should be done about it during the
install, at startup or as part of the null plugin (something like a warning
message saying that the plugins are there but unusable because of missing libraries.

Comment 4

[Olivier Dragon]

I'm using XFree86 v4.0.2, with packages in debian unstable (4.0.2-7)

After uninstalling
-xlib6g-dev (pseudo-package depending on the later two)
-xlibs-dev
-libxaw-dev

I've noticed that the plugins weren't working anymore ("about:plugins" not
listing anything else than the null-plug). I then installed only

xlibs-dev

and without even restarting Mozilla, just reloading "about:plugins" and the
plugins were showing as working properly.

Comment 8

[Olivier Dragon]

right that sounds very much like bug 69167. Status should be changed to dup I think.

Comment 9

[Boris Zbarsky [:bzbarsky]]

If you think, so, I think so.  Marking duplicate.
