gdb本地調(diào)試版本移植至ARM-Linux系統(tǒng)
加入技術(shù)交流群
本文使用的ncurses版本為ncurses-5.9.tar.gz
下載地址：https://ftp.gnu.org/gnu/ncurses/ncurses-5.9.tar.gz
1. 將ncurses壓縮包拷貝至Linux主機或使用wget命令下載并解壓
tar-zxvf ncurses-5.9.tar.gz
2. 解壓后進入到ncurses-5.9目錄下
cdncurses-5.9
3. 在ncurses-5.9目錄下創(chuàng)建編譯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=$PWD/output/arm-linux --enable-termcap --with-shared --without-ada
l --target表示編譯器的前綴，需要根據(jù)編譯的不同需求進行修改
l --prefix表示編譯完成后生成文件的位置
l --nable-termcap表示 關(guān)鍵代碼使用 termcap(terminalcapabilities)數(shù)據(jù)庫 [自動檢測]
l --with-shared表示動態(tài)編譯
5. 編譯
make
當遇到如下報錯時
Makefile:794:recipe for target '../obj_s/lib_gen.o' failed
make[1]:*** [../obj_s/lib_gen.o] Error 1
make[1]:Leaving directory '.../ncurses-5.9/ncurses'
Makefile:109:recipe for target 'all' failed
make:*** [all] Error 2
需要進入ncurses-5.9/include文件夾，修改 curses.tail 文件下的如下內(nèi)容,將注釋 /* generated */ 去掉
externNCURSES_EXPORT(bool) mouse_trafo(int*, int*, bool); /* generated*/
6. 安裝
Makeinstall
7. 安裝完成后會在/output/arm-linux目錄下生成庫文件，我們只需將lib目錄下的libncurses.so.5 庫拷貝至開發(fā)板
移植gdb
本文使用的gdb版本為gdb-7.12.tar.gz
下載地址：https://ftp.gnu.org/gnu/gdb/gdb-7.12.tar.gz
1. 將gdb壓縮包拷貝至Linux主機或使用wget命令下載并解壓
tar-zxvf gdb-7.12.tar.gz
2. 解壓后進入到ncurses-5.9目錄下
cdgdb-7.12
3. 生成Makefile文件
./configure -host=arm-none-linux-gnueabi CC=/home/vanxoak/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-gcc --enable-shared--prefix=$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編譯
l CC為交叉編譯器絕對路徑
l --enable-shared 動態(tài)編譯
l prefix=“$PWD/output/arm-linux” 安裝目錄
l --disable-werror 屏蔽werror報警
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 去掉用于多語言處理的gettext庫
l "LDFLAGS=XXX"指交叉編譯完成的ncurse的lib目錄路徑
l "CPPFLAGS=XXX"指是交叉編譯完成的ncurse的include目錄路徑
4. 編譯
make
5. 安裝
makeinstall
安裝完成后會在.../gdb-7.12/output/arm-linux/bin/目錄下生成gdb可執(zhí)行程序。
移植至HDT3-EVM 開發(fā)板
1. 將libncurses.so.5庫 文件拷貝至/usr/lib目錄下，若/usr目錄下無lib目錄可手動創(chuàng)建mkdir lib
2. 將gdb程序拷貝至/bin目錄下
測試調(diào)試
1. 編寫可執(zhí)行測試程序，示例hello.c代碼如下,該代碼執(zhí)行后會打印Hello World。
#include<stdio.h>
intmain(int argc, char *argv[])
{
printf("Hello World\n");
return 0;
}
2. 使用交叉編譯器進行編譯，需要注意的是，要使用gdb調(diào)試程序，需要在使用交叉編譯器編譯源代碼時加上 " -g " 參數(shù)保留調(diào)試信息，否則不能使用GDB進行調(diào)試且報如下最后一行所示錯誤:

Readingsymbols from hello...(no debugging symbols found)...done.
3. 使用交叉編譯器編譯測試程序
arm-none-linux-gnueabi-gcc-g -o hello hello.c
4. 將生成的hello文件拷貝至HDT3-EVM 開發(fā)板上并使用sync命令保存
5. 輸入gbd命令啟動gdb程序
/home# gdb

(gdb)
上述代碼(gdb)為GBD內(nèi)部命令引導(dǎo)符,表示等待用戶輸入gbd命令
6. 使用 " file hello " 命令載入被調(diào)試的測試程序
(gdb)file hello
Readingsymbols from hello...done.
顯示Reading symbols from hello...done.表示被測程序加載成功
7. 使用 " r "命令執(zhí)行調(diào)試測試程序
(gdb)r
Startingprogram: /home/hello
HelloWorld
[Inferior1 (process 849) exited normally]
如上述代碼顯示 " Hello World " 即表示hello程序執(zhí)行完成
