新路程------GDB 调试(1)

  首先下载gdb-7.12.tar.gz(在我的资源中可以直接下载)

 然后解压到任意目录，我解压在Document里matt@ubuntu:~$ tar -zxvf gdb-7.12.tar.gz

 然后cd gdb-7.12然后

matt@ubuntu:~/Documents/gdb-7.12$ ./configure

在此之前我安装了

texinfo，libncurses5-dev, m4, flex 和 bison这5个包

就是apt-get install texinfo之类的cmd就可以了

然后

 matt@ubuntu:~/Documents/gdb-7.12$ make

然后

matt@ubuntu:~/Documents/gdb-7.12$ sudo make install

这样就装好了gdb

不过ubuntu14.04自带gdb，所以这个安装过程也只供参考

如果编译海思的gdb server，则命令如下：

matt@ubuntu:~/Documents/gdb-7.12/gdb/gdbserver$ CC=arm-hisiv300-linux-gcc ./configure --host=arm-hisiv300-linux  --target=arm-hisiv300-linux


matt@ubuntu:~/Documents/gdb-7.12/gdb/gdbserver$ make


matt@ubuntu:~/Documents/gdb-7.12/gdb/gdbserver$ file gdbserver
gdbserver: ELF 32-bit LSB  executable, ARM, EABI5 version 1 (SYSV), dynamically linked (uses shared libs), not stripped


matt@ubuntu:~/Documents/gdb-7.12/gdb/gdbserver$ arm-hisiv300-linux-strip gdbserver -o gdbserver
matt@ubuntu:~/Documents/gdb-7.12/gdb/gdbserver$ file gdbserver
gdbserver: ELF 32-bit LSB  executable, ARM, EABI5 version 1 (SYSV), dynamically linked (uses shared libs), stripped

而编译imx6的gdb server则是：

matt@ubuntu:~/Documents/gdb-7.12/gdb/gdbserver$ CC=arm-fsl-linux-gnueabi-gcc ./configure --host=arm-fsl-linux-gnueabi  --target=arm-fsl-linux-gnueabi

arm-fsl-linux-gnueabi-strip gdbserver -o gdbserver

而但凡目标开发板是arm内核的，gdb的编译命令都是

root@P310:~/Documents/gdb-7.12# ./configure --target=arm-linux --prefix=/usr/local/arm-gdb  后面这个是生成arm-linux-gdb的目录

在这个目录下执行

root@P310:/usr/local/arm-gdb/bin# gdb
