Porting open NTP to arm platform

Work needs ah, need to transplant open source NTP to arm926 platform.

(1) Now Source: http://www.ntp.org/downloads.html

I'm under version: 4.2.8P1

(2) Unzip and place it where you like.

(3) Read the Readme file carefully and follow the steps it says to start compiling

(4) configuration./configure, you can add some parameters, I use a script to do this process:

#!/bin/bash. /configure cc=/opt/sourcery-arm-201203/bin/arm-none-linux-gnueabi-gcc cppflags=-i/home/xxx/ openssl-1.0. 2/include ldflags=-s libs=-l/home/xxx/ntp-4.2. 8p1/openssl-installed/lib--prefix=/home/xxx/ntp- 4.2. 8p1--exec-prefix=/home/xxx/ntp-4.2. 8P1--host=arm-none-linux-gnueabi--with-yielding-  Select=yes--enable-openssl >&./xxx_config-host

CC=/OPT/SOURCERY-ARM-201203/BIN/ARM-NONE-LINUX-GNUEABI-GCC: specifying Cross Compiler

Cppflags=-i/home/xxx/openssl-1.0.2/include: You need to use the OpenSSL library for compilation, so you have to compile the OpenSSL library before you can view the previous article: Arm-linux porting OpenSSL. This specifies the path of the inventory drop

Ldflags=-s: Not clear the reason, anyway, with the connection library specified in the following, do not seem to add

Libs=-l/home/xxx/ntp-4.2.8p1/openssl-installed/lib: Make will find Lib library file, specify the location to find, this is different from the above cppflags, but also to specify

--prefix=/home/xxx/ntp-4.2.8p1--exec-prefix=/home/xxx/ntp-4.2.8p1  : These two steps specify where the compiled files are stored, ( Seems to have not worked very well, should be my personal situation, in short add)

--host=arm-none-linux-gnueabi: Specifies the environment for late-running devices, which is somewhat similar to the target platform

--with-yielding-select=yes : Plus, no side hints not configured

--enable-openssl: Plus don't know if it's useless, anyway.

>&./xxx_config-host: The compilation process is printed to a file for easy observation, can be deleted
Note the point:
CC's designation must be in front, put in the end seems not to

(5) Run this script and configure OK after it is finished. Then it is make, it should be made successful, and the execution file appears in the respective directory.

(6) According to the needs of the evening compiling process and operating environment, to this point, the compilation of the approximate end.
