Cross Compiling

[sirmuzz]

Hello,

I have a need to debug some lua code running on a remote router. I have been attempting to get this to compile in the cross-compiler and have little luck. I was unable to past an errorr_r error in the includes using the included asio library, but have been able to build it with boost.

I believe i have most of the includes needed to build it properly. Can you see anything i am doing wrong? I have not been able to get it to go in cross yet.

include $(TOPDIR)/rules.mk

Any help would be appreciated. Im not a well versed C/C++ developer and this has gotten my goat for a week.

Thank you!
