Programming In C/C - MEDIATEK LinkIt Smart 7688 Developer's Manual

In addition to being used by the device application to access remote systems or cloud services
over the Internet, this mode is used to install software from OpenWrt to the board using
package manager. In this scenario, your computer joins the same Wi-Fi network as the board and
connects to the board through SSH.

Programming in C/C++

Native applications require toolchain programs to compile and link C/C++ source code into
executable binaries. While you can install development tools on LinkIt Smart 7688 Linux
environment directly, the board's 128MB of RAM may be insufficient for use and this can become a
limitation for native application developments.
To avoid running out of memory during native application developments, you should setup the
native application development environment in a more powerful host environment that enables
you to cross-compile the executable format of the LinkIt Smart 7688 target instead.
3.6.1. Setting up C/C++ Programming Environment
The cross compilation toolchain is included in the software package of LinkIt Smart 7688 SDK and
supports Mac OS X and Linux. Windows isn't supported at the time of writing.
To use the toolchain, download and unzip it to a directory of your choice and denote the toolchain
CC_TOOLS
directory as .
