BUG report: 64bit flash does not work in chromium after updating by emerge -auDN world

I am not 100% sure if it is a bug, but i am going to post the problem, and my solution here.

After update the system(64bit CLDG) by ,

emerge -auDN world

the flash does not work in chromium, it shows the following in terminal

/usr/lib64/nspluginwrapper/i386/linux/npviewer.bin: /usr/lib64/nspluginwrapper/i386/linux/npviewer.bin: cannot execute binary file

to solve this issue

emerge nspluginwrapper

For the flash, download 64bit adobe flash from adobe(search it on google…)

mkdir /usr/lib64/chromium-browser/plugins

copy libflashplayer.so /usr/lib64/chromium-browser/plugins

restart the chromium, it should work fine now

The latest version of www-plugins/adobe-flash to 64-bit. Try to update again today available later.
