Ubuntu compiled ARM-LINUX-GCC toolchain--making toolchain from Crosstool-ng

1. save time by manually downloading the required packages in the production process

the packages used are as follows ( Different versions of all package versions differ )

libtool-2.4.6

linux-3.2.87

gmp-6.1.2

mpfr-3.1.5

isl-0.16.1

glibc-2.25

duma_2_5_15

gdb-7.12.1

ltrace-0.7.3

strace-4.16

2. Preparation of tool chain production

Enter Crosstool Directory: CD ~/.crosstool

Execution: Ct-ng list-samples

Select Arm-unknown-linux-gnueabi as a template for the compilation tool chain

Execute command: Ct-ng Show-arm-unknown-linux-gnueabi To view the configuration required to compile the build tool chain

Download gcc 6.3.0 : wget http://ftp.gnu.org/gnu/gcc/gcc-6.3.0/gcc-6.3.0.tar.gz　　

Execute command: Ct-ng Arm-unknown-linux-gnueabi　

Execute command: Ct-ng Menuconfig　

Select Target Options

　　Target optimisations * * *

(ARMV4T) Architecture level: instruction set architecture,

(arm920t) Emit assembly for Cpu:cpu core Type, -mcpu=name

() Tune for CPU : To CPU can view the chip manual, -mtune=name

the latest version of Crosstool-ng just need to select the 12th item just fine.

Select toolchain Options:　　

3. start compiling:

Execute command: Ct-ng Build

Compilation succeeded:

To set all user environment variables:

Vim/etc/profile

The first line is added as follows

Export path=/home/liu/arm9/tools/ Set the path /bin: $PATH

Save and exit, the update takes effect:

Source/etc/profile

Perform

arm-s3c2440a-linux-gnueabi-gcc-v

u-boot 2016.01 not supported GCC6 , so want to put GCC version is changed to GCC5.0 version --gcc6.0 between versions.
