Tiny4412 Cross-compilation environment construction

Cross-compiling: Develop the program on the PC (x86 platform), run on the arm board, improve the speed of development and compilation.

Environment:

tiny4412sdk1506 Development Board

Software Required:

Arm-linux-gcc-4.5.1-v6-vfp-20120301.tgz

Detects if the system has a cross-compilation environment installed:

# arm-linux-gcc-v
Bash:arm-linux-gcc:command not found

Installation Steps :

1, find the path of arm-linux-gcc-4.5.1-v6-vfp-20120301.tgz, and unzip the compressed file

# tar XF arm-linux-gcc-4.5.1-v6-vfp-20120301.tgz 
# ls
arm-linux-gcc-4.5.1-v6-vfp-20120301.tgz  opt

Unzip to get an opt folder

2. Create a folder in the usr/local/directory and unzip the folder./OPT/FRIENDLYARM/TOOLSCHAIN/4.5.1/Copy to/usr/local/arm/directory:

# mkdir/usr/local/arm
# cp OPT/FRIENDLYARM/TOOLSCHAIN/4.5.1//usr/local/arm/-RF

3, modify the environment variables:

# vim/root/.bash_profile 
added:
path=/usr/local/arm/4.5.1/bin/: $PATH
Export PATH

4, log off users, re-login to the user after the effective

Or:

Source/root/.bash_profile

Make the configuration file effective.

5. Detect if the cross-compilation environment is installed successfully:

# arm-linux-gcc-v ...
GCC version 4.5.1 (CTNG-1.8.1-FA) 

A cross-compilation environment version of 4.5.1 was detected, and the installation was successful.
