本文使用的ncurses版本为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=$PWD/output/arm-linux --enable-termcap --with-shared --without-ada
5. 编译
make
当遇到如下报错时
Makefile:794:recipe for target '../obj_s/lib_gen.o' failed
make[1]:*** [../obj_s/lib_gen.o] Error 1
make[1]:Leaving directory '.../ncurses-5.9/ncurses'
Makefile:109:recipe for target 'all' failed
make:*** [all] Error 2
需要进入ncurses-5.9/include文件夹,修改 curses.tail 文件下的如下内容,将注释 /* generated */ 去掉
externNCURSES_EXPORT(bool) mouse_trafo(int*, int*, bool); /* generated*/
6. 安装
Makeinstall
7. 安装完成后会在/output/arm-linux目录下生成库文件,我们只需将lib目录下的libncurses.so.5 库拷贝至开发板
本文使用的gdb版本为gdb-7.12.tar.gz
1. 将gdb压缩包拷贝至Linux主机或使用wget命令下载并解压
tar-zxvf gdb-7.12.tar.gz
2. 解压后进入到ncurses-5.9目录下
cdgdb-7.12
3. 生成Makefile文件
./configure -host=arm-none-linux-gnueabi CC=/home/vanxoak/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-gcc --enable-shared--prefix=$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"
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。
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
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
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:

3. 使用交叉编译器编译测试程序
arm-none-linux-gnueabi-gcc-g -o hello hello.c
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
/home# gdb

(gdb)
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
(gdb)help
