Software: - RedHat 5.1 (i386), with all the current updates (including netscape 4.06). - Acrobat reader 3.01 (installed using the acrobat-3.01-1.nosrc.rpm at ftp.redhat.com with some minor modifications to the spec file). I am having a hell of a time trying to get acrobat reader working as a "helper application" with netscape. It just doesn't work. After much investigation, it seems that acroread is segfaulting somewhere in the shared libraries (strace output is vague, and gdb gives no useful information from the core dump). Both netscape (4.05 and 4.06) and acroread work just fine on their own. But not acroread from within netscape as a helper. (acroread is linked against the libc5 libraries, which, according to the strace dump, are -eventually- being found). Is there any way to fix things so that it works? (Eg, does the /usr/bin/netscape script that comes with the netscape rpm need to be modified with an LD_LIBRARY_PATH or something similar?) BTW, ldd (from glibc-2.0.7-19) doesn't seem to know about /etc/ld.so.cache... why is it so brain-dead? Ideally, I'd really like to use the nppdf.so plugin supplied with acroread instead of using acroread as a helper application... but: - the "plugin" button is greyed out and inactive in netscape's Edit:Preferences:Navigator:Applications:New menu (and :Edit menu). - set $NPX_PLUGIN_PATH to point to /usr/Acrobat3/Browsers/intellinux/ (where the plugin lives) - but it complains about a missing libc.so.5. - fixed the libc.so.5-not-found problem with symlinks from /usr/Acrobat3/Browsers/intellinux/libc.so.5 and /lib/libc.so.5 -> ../usr/i486-linux-libc5/lib/libc.so.5.3.12 (not sure which one did the trick:) - "about plugins" shows me that the pdf plugin is there and available, but NOT enabled! :-( Why not? So how do you install and enable plugins with netscape 4.05/4.06? Or is this disabled deliberately? (I'd like to eventually get things like realaudio working too, but I'm wondering if this can be done at all). Many thanks for any help. Cheers Tony
