I have compiled the 3.05 version on my RedHat Linux Enterprise Server v3 with any problem using the following configuration:

./configure --enable-gtk1 --with-gecko-sdk=/shared/Mplayer/gecko-sdk.

However,  when I start my Netscape ( using Mozilla 1.7.10, Copyright (c) 2003-2004 mozilla.org, build 2005071922 ) I obtain this message:

LoadPlugin: failed to initialize shared library /usr/local/netscape72/plugins/mplayerplug-in.so [/usr/local/netscape72/plugins/mplayerplug-in.so: undefined symbol: _Z24menuitem_config_callbackP12_GtkMenuItemP16nsPluginInstance]

What other llibrary do I have to include to obtain the reference to that symbol?

Thanks in advance for any information
