Hi

I tried executing it directly, but it doesn't work. My kernel shouldhave
Linux compat. compiled in. Can I check that at runtime, to be 100%?


Hm, "sysctl emul.linux"?  I believe that shouldn't give anything unless
you have it in your kernel.

Btw, I paste here the last part of "ktrace -i opera" as interpreted bykdump. I cannot attach the file because thunderbird and firefox (bothgtk apps) will crassh when they pop-up the file browser... but that isanother issue!
