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/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 (mips平台)
注：本人在DM365上实验，命令为：
./configure --target=arm-linux --host=arm-linux --program-prefix=arm-linux --prefix=/home/xinyz/gdb/gdb CC=/opt/linux-devkit/bin/arm-arago-linux-gnueabi-gcc AR=/opt/linux-devkit/bin/arm-arago-linux-gnueabi-ar --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.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/PACKAGE]
--htmldir=DIR html documentation [DOCDIR]
--dvidir=DIR dvi documentation [DOCDIR]
--pdfdir=DIR pdf documentation [DOCDIR]
--psdir=DIR ps documentation [DOCDIR]

重点提示：
多线程调试时， 会出现 Program received signal SIG32, Real-time event 32 的解决办法
1：在gdb模式下，执行 handle SIG32 pass noprint nostop
2:编译程序时， gcc 加上-static
