交叉编译GDB工具， 使GDB运行在嵌入式板子上

1：下载gdb-7.3a.tar.gz (本示例使用gdb-7.3.a)

        
地址http://ftp.gnu.org/gnu/gdb/

2: 解压上文件

        
tar –zxvf gdb-7.3a.tar.gz

3: 开始配置编译

  (1)：进入目录， 上述解压生成默认的目录是gdb-7.3

   (2): ./configure
--target=mipsel-linux --host=mipsel-linux
--program-prefix=mipsel-linux
--prefix=/home/Samman/test/gdb-7.3/sunyg
CC=/opt/buildroot-gcc342/bin/mipsel-linux-gcc --enable-static

--target=>目标平台 当前制定为mips， 或者arm-linux

--host=>程序运行的机器， 注意这个值会影响程序里面的ar等命令的前缀，

如上述， 指定host为mipsel-linux, 那么程序文件的makefile
里面的就会出现AR=mipsel-linux-ar

--program-prefix 制定生成gdb, gdbserver 名字前面会加上这些

--prefix 指定 make install 的安装目录， 当前使用绝对路径， 最后成功的话， 会在sunyg目录生成
mipsel-linux-gdb…….

CC 指定交叉编译工具

--enable-static 静态加载库

4: make;make install

5：特别注意

           
(1): 需要指定环境变量，export PATH=$PATH:/opt/buildroot-gcc342/bin

                  
程序执行时会用到其他的交叉编译工具 mipsel-linux-ar, mipsel-linux-strip等等

(2) 这个版本编译需要文件gdbreplay.c 中变量fromgdb 这个值初始化 （赋值为0即可）

6: 恭喜你， 大功告成

        
file sunyg/* 查看文件， 是否为static ， 是否striped， 默认应该没有

        
你可以手动strip

   Mipsel-linux-strip
mispel-linux-gdb –o mipsel-linux-gdb

 

 

 

以下是configure的help

 

./configure --help

`configure' configures this package to adapt to many kinds of
systems.

 

Usage: ./configure [OPTION]... [VAR=VALUE]...

 

To assign environment variables (e.g., CC, CFLAGS...), specify
them as

VAR=VALUE.  See below for descriptions of some
of the useful variables.

 

Defaults for the options are specified in brackets.

 

Configuration:

  -h,
--help             
display this help and exit

     
--help=short       
display options specific to this package

     
--help=recursive   
display the short help of all the included packages

  -V,
--version          
display version information and exit

  -q, --quiet,
--silent   do not print
`checking...' messages

     
--cache-file=FILE   cache test
results in FILE [disabled]

  -C,
--config-cache     
alias for `--cache-file=config.cache'

  -n,
--no-create        
do not create output files

     
--srcdir=DIR       
find the sources in DIR [configure dir or `..']

 

Installation directories:

 
--prefix=PREFIX        
install architecture-independent files in PREFIX

                         
[/usr/local]

 
--exec-prefix=EPREFIX   install
architecture-dependent files in EPREFIX

                         
[PREFIX]

 

By default, `make install' will install all the files in

`/usr/local/bin', `/usr/local/lib' etc.  You
can specify

an installation prefix other than `/usr/local' using
`--prefix',

for instance `--prefix=$HOME'.

 

For better control, use the options below.

--bindir=DIR           
user executables [EPREFIX/bin]
