The document discusses cross compiling C/C++ programs for the LinkIt Smart 7688 device. It explains setting up the toolchain environment and PATH variable to access the compiler. It then shows compiling a simple "Hello World" C program using gcc, copying the compiled program to the LinkIt device, and how to configure a kit for building and running programs on the device in the LinkIt IDE.

1. Cross Compile

2. Toolchain
