Re: LuaJIT on webOS HP TouchPad (arm7l linux)

[Tim Caswell <tim@...>]

Nice work.  Though it doesn't work for me.  I'm on 64 bit Ubuntu 11.10
and I get the following error:

gcc -m32  -O2 -fomit-frame-pointer -Wall
-DLUAJIT_TARGET=LUAJIT_ARCH_arm  -c -o buildvm_fold.o buildvm_fold.c
In file included from buildvm_asm.c:6:0:
buildvm.h:9:23: fatal error: sys/types.h: No such file or directory
compilation terminated.


I've always built luajit on my touchpad, but I'd like to be able to
cross-compile it also.
