Hi!
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 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.
Question: is there a proper fix for these problems???
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:
--- acroread.orig 2008-10-08 06:28:27.000000000 +0200
+++ acroread 2008-12-08 22:59:46.000000000 +0100

- exec /lib/ld-linux.so.2 ${1+"$@"}
+ TEMP_LIB_PATH="$LD_LIBRARY_PATH"
+ unset LD_LIBRARY_PATH
+ exec /lib/ld-linux.so.2 --library-path "$TEMP_LIB_PATH" ${1+"$@"}
else
exec ${1+"$@"}
fi
which indeed works!
