This article proposes an easy way to develop application written in C/C++ for running on MIPS Debian 8.1 platform by cross-compiling in Netbeans IDE environment. The target board is IOT+ board which embedded an Ingenic jz4780 MIPS processor. The host machine is running Ubuntu 14.04 LTE.

Software Requirement On Host Platfrom:

Target platform: IOT+ Board

Specification: MIPS Dual core CPU 1.2G Hz - Ingenic jz4780 HDMI up to 2K 3 x USB 2.0 socket 2 x 10/100 BaseT Ethernet socket  WiFi built-in SD card socket for system boot RAM 1G DDR3, NAND memory 4G GPIO, SPI, I2C, ADC, UART, JTAG sensors/interface Header footprint for camera connection Powered from 5V power

Firstly, on the host platform, dump the Debian 8.1 MIPS image to uSD and insert into the PC on USB port. It should be mounted automatically ,assume it is on

 /media/user/rootfs

As a root user, run the following commands to create the symbolic links 

$ ln -s /media/user/rootfs/lib/mipsel-linux-gnu	/lib
$ ln -s /media/user/rootfs/usr/lib/mipsel-linux-gnu /usr/lib

Next uncompressing the Sourcery CodeBench Lite compiler tool chain "mips-2015.11-32-mips-linux-gnu-i686-pc-linux-gnu.tar.bz2" to /opt, assume the destination folder is "mips-2015.11". The absolute installation path will be

/opt/mips-2015.11

The path /media/user/rootfs and /opt/mips-2015.11 will be needed on setting up Netbeans IDE. Now, following below articles on adding Sourcery CodeBench Lite compiler to Netbean IDE and see how to write C/C++ programs for cross-compiling.
