arm 单片机交互编译资apache料整理

理清思路其实交互编译就是把x.86下程序用arm版本的编译器重新编译。存在兼容问题所以之需要在原来x.86下可以通过的
代码重新使用arm gcc make 即可下面是大概的步骤


How to Apache Cross Compile 

OS : CentOS
Kernel : 2.6
Machine : x.86

Target arm
OS : linux 
Kernel : 2.4.18
Machine : arm (TS-7250)


#1.   Download apache file at 
version apache_1.3


#2. unzip software
[root@wc02 utils]# tar xvfz apache_1.3.33.tar.gz 


#3. change to two version GCC files
[root@wc02 utils]# cp apache_1.3.33 host_apache_1.3.33 -a


#4.start 2 tty prepare compile

[root@wc02 utils]# cd host_apache_1.3.33/

[root@wc02 host_apache_1.3.33]# mkdir /usr/local/apache/

[root@wc02 host_apache_1.3.33]# ./configure --prefix=/usr/local/apache/

 + setting C compiler to gcc
 + setting C pre-processor to gcc -E
 + using "tr [a-z] [A-Z]" to uppercase
 + checking for system header files
 + adding selected modules
 + using system Expat
 + checking sizeof various data types
 + doing sanity check on compiler and options

[root@wc02 host_apache_1.3.33]# 
[root@wc02 host_apache_1.3.33]# make 

这里是我们编译x.86版本的编译。肯定可以通过。注意我们不是要安装所以不需要
make install。把代码放到这里准备


#5.  arm GCC configure 

[root@wc02 src]# export CC=arm-linux-gcc
[root@wc02 src]# export CPP=arm-linux-gcc
[root@wc02 src]# export LD=arm-linux-ld
[root@wc02 src]# export STRIP=arm-linux-strip
[root@wc02 src]# export OBJCOPY=arm-linux-objcopy

[root@wc02 apache_1.3.33]# vi configure 
##
##  determine platform id
##
## PLATFORM="`$aux/GuessOS`" <----------- OS版本这里没有我们支持的只能写死否则出错.
PLATFORM=arm-whatever-riscix


#6.   开始编译
[root@wc02 apache_1.3.33]# ./configure --prefix=/usr/local/apache

[root@wc02 apache_1.3.33]# 


arm-linux-gcc 在这里出错。不要紧我们现编的步骤就是准备解决这些x.86不识别我们arm 软件的编译错误



#7. (Root_dir)/src/main 

[root@wc02 main]# make ../../../host_apache_1.3.33/src/main/gen_test_char


[root@wc02 main]# make ../../../host_apache_1.3.33/src/main/gen_test_char
 



#8.   Change compiled file at host pc

[root@wc02 main]# cp ../../../host_apache_1.3.33/src/main/gen_test_char ./
[root@wc02 main]# cp ../../../host_apache_1.3.33/src/main/gen_uri_delims ./


#9.   make install
好了程序正常建立我们可以开始安装

[root@wc02 apache_1.3.33]# make install
