Try using the -v option, and you see what is wrong!
Code:
nspluginwrapper -v -i /usr/local/src/libflashplayer.so
*** NSPlugin Viewer *** ERROR: libssl3.so: cannot open shared object file: No such file or directory
*** NSPlugin Viewer *** ERROR: libssl3.so: cannot open shared object file: No such file or directory
nspluginwrapper: no appropriate viewer found for /usr/local/src/libflashplayer.so
For slackware64 14.1
You need at least seamonkey-solibs-compat32-2.26.1-x86_64-1_slack14.1compat32
And you also need to set up the library search path in /etc/ld.so.conf
/usr/lib/seamonkey
(remember to run ldconfig afterwards)
Code:
nspluginwrapper -v -i /usr/local/src/libflashplayer.so
Install plugin /usr/local/src/libflashplayer.so
into /home/morten/.mozilla/plugins/npwrapper.libflashplayer.so
Enjoy
