>Description:
When testing acroread8 (on 7.1-PRE) I got the following error when
trying to print using KDE's kprinter on i386:
The following error occurred while printing...
'/libexec/ld-elf.so.1: /usr/local/Adobe/Reader8/ENU/Adobe/Reader8/Reader/intellinux/lib/libstdc++.so.6: unsupported file layout'
and on amd64:
The following error occurred while printing...
'/libexec/ld-elf.so.1: Shared object "libm.so.6" not found, required by "libstdc++.so.6"'
The reason is that the acroread launch script sets LD_LIBRARY_PATH to:
LD_LIBRARY_PATH=/usr/local/Adobe/Reader8/ENU/Adobe/Reader8/Reader/intellinux/lib:/usr/local/Adobe/Reader8/ENU/Adobe/Reader8/Reader/intellinux/sidecars:/..//usr/local/lib/linux-nvu
which makes (some) helper programs fail to link its shared libs if it
happens to pick up a (Linux) library from the above. libstdc++.so.6
is one of them.
The problem also exist for launching a browser.
>How-To-Repeat:
Enter "kprinter" as the print program in the print dialogue, or try to
use firefox as the browser (in edit/preferences/internet). The latter
does however not result in an error message.
>Fix:
The problem is easily worked around for the print program - you can do
"env -u LD_LIBRARY_PATH kprinter" for instance directly in the print
dialogue. But that does not work for the browser executable set in
the "edit/preferences/internet" dialogue. So if you want to be able
to launch a browser from acroread, you need a wrapper script.
I see that the Linux dynamic linker
(/usr/compat/linux/lib/ld-linux.so.2) has a flag:
--library-path PATH use given PATH instead of content of the environment
variable LD_LIBRARY_PATH
so I tried to patch the acroread launch script in
/usr/local/Adobe/Reader8/ENU/Adobe/Reader8/bin with:

fi
Question: what is a proper fix for these problems???
