gdb本地调试版本移植至ARM-Linux系统

移植ncurses库

本文使用的ncurses版本为ncurses-5.9.tar.gz

下载地址：https://ftp.gnu.org/gnu/ncurses/ncurses-5.9.tar.gz

1.???????将ncurses压缩包拷贝至Linux主机或使用wget命令下载并解压

tar-zxvf?ncurses-5.9.tar.gz

2.???????解压后进入到ncurses-5.9目录下

cdncurses-5.9

3.???????在ncurses-5.9目录下创建编译完成后生成文件位置

mkdiroutput

cdoutput

mkdirarm-linux

4.???????生成Makefile文件

./configure--target=arm-none-linux-gnueabi?--prefix=$PWD/output/arm-linux??--enable-termcap?--with-shared?--without-ada

l??--target表示编译器的前缀，需要根据编译的不同需求进行修改

l??--prefix表示编译完成后生成文件的位置

l??--nable-termcap表示?关键代码使用?termcap(terminalcapabilities)数据库?[自动检测]

l??--with-shared表示动态编译

5.???????编译

make

当遇到如下报错时

Makefile:794:recipe?for?target?'../obj_s/lib_gen.o'?failed

make[1]:***?[../obj_s/lib_gen.o]?Error?1

make[1]:Leaving?directory?'.../ncurses-5.9/ncurses'

Makefile:109:recipe?for?target?'all'?failed

make:***?[all]?Error?2

需要进入ncurses-5.9/include文件夹，修改?curses.tail?文件下的如下内容,将注释?/*?generated?*/?去掉

externNCURSES_EXPORT(bool)????mouse_trafo(int*,?int*,?bool);?????????/*?generated*/

6.???????安装

Makeinstall

7.???????安装完成后会在/output/arm-linux目录下生成库文件，我们只需将lib目录下的libncurses.so.5?库拷贝至开发板

移植gdb

本文使用的gdb版本为gdb-7.12.tar.gz

下载地址：https://ftp.gnu.org/gnu/gdb/gdb-7.12.tar.gz

1.???????将gdb压缩包拷贝至Linux主机或使用wget命令下载并解压

tar-zxvf?gdb-7.12.tar.gz

2.???????解压后进入到ncurses-5.9目录下

cdgdb-7.12

3.???????生成Makefile文件

./configure?-host=arm-none-linux-gnueabi?CC=/home/vanxoak/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-gcc??--enable-shared--prefix=$PWD/output/arm-linux?--disable-werror?--without-x?--disable-gdbtk--disable-tui?--without-included-regex?--without-included-gettextLDFLAGS="-L$PWD/../output/arm-linux/lib"CPPFLASS="-I$PWD/../output/arm-linux/include"

l??--host=arm-none-linux-gnueabi?用arm-none-linux-gnueabi编译

l??CC为交叉编译器绝对路径

l??--enable-shared?动态编译

l??prefix=“$PWD/output/arm-linux”?安装目录

l??--disable-werror?屏蔽werror报警

l??--without-x?取消x?windows?支持

l??--disable-gdbtk?取消gdbtk

l??--disable-tui?取消tui?界面

l??--without-included-gettext?去掉用于多语言处理的gettext库

l??"LDFLAGS=XXX"指交叉编译完成的ncurse的lib目录路径

l??"CPPFLAGS=XXX"指是交叉编译完成的ncurse的include目录路径

4.???????编译

make

5.???????安装

makeinstall

安装完成后会在.../gdb-7.12/output/arm-linux/bin/目录下生成gdb可执行程序。

移植至HDT3-EVM?开发板

1.???????将libncurses.so.5库?文件拷贝至/usr/lib目录下，若/usr目录下无lib目录可手动创建mkdir?lib

2.???????将gdb程序拷贝至/bin目录下

?

测试调试

1.??编写可执行测试程序，示例hello.c代码如下,该代码执行后会打印Hello?World。

#include<stdio.h>?

intmain(int?argc,?char?*argv[])?

{?

????printf("Hello?World\n");?

????return?0;?

}

2.??使用交叉编译器进行编译，需要注意的是，要使用gdb调试程序，需要在使用交叉编译器编译源代码时加上?"?-g?"?参数保留调试信息，否则不能使用GDB进行调试且报如下最后一行所示错误:

4.???????将生成的hello文件拷贝至HDT3-EVM?开发板上并使用sync命令保存

5.???????输入gbd命令启动gdb程序

上述代码(gdb)为GBD内部命令引导符,表示等待用户输入gbd命令

6.???????使用?"?file?hello?"?命令载入被调试的测试程序

(gdb)file?hello

Readingsymbols?from?hello...done.

显示Reading?symbols?from?hello...done.表示被测程序加载成功

7.???????使用?"?r?"命令执行调试测试程序

(gdb)r

Startingprogram:?/home/hello

HelloWorld

[Inferior1?(process?849)?exited?normally]

如上述代码显示?"?Hello?World?"?即表示hello程序执行完成
