Re: LuaJIT on webOS HP TouchPad (arm7l linux)

["Dimiter \"malkia\" Stanev" <malkia@...>]

I was compiling on my OSX.

Maybe -isysroot must be changed with --sysroot?
Or maybe you don't have the latest PalmPDK?

If I have time I'll try it today on Linux.

Btw, I'm actually interrested in compiling (also git, bintools, gcc) and 
having them installed on my touchPad :) Anything prebuilt out there?

Thanks!
