gdb远程使用

1.编译时加-g

2.gdbserver + gdb 远程调试
prebuilts/toolchains/mips-gcc720-glibc226/mips-linux-gnu/libc/mfp64/usr/bin/gdbserver 
把它拷贝到target

3.target
gdbserver 宿主机 IP:端口号 要调试的可执行程序
#./gdbserver 192.168.0.240:50555 ./cloud_sound_dance

4.host
mips-linux-gnu-gdb 要调试的可执行程序
#mips-linux-gnu-gdb tmp_files/cloud_sound_dance

target remote 目标板 IP:端口号
(gdb) target remote 192.168.0.174:50555

5.设置断点,运行：
(gdb) b App.cpp:308
Breakpoint 1 at 0x454834: file ../App.cpp, line 308.
(gdb) r
The "remote" target does not support "run".  Try "help target" or "continue".
(gdb) continue
Continuing.

(gdb) info breakpoints
