我尝试使用gdb 7.7为嵌入式Linux平台设置远程调试，运行使用＆＃34; i586-geode-linux-gnu-gcc（crosstool-NG 1.19.0）4.8编译的代码。 1＆＃34;
此处使用的示例是以下程序：
#include <stdio.h>
#include <stdlib.h>
int main(char* argc, char* argv[])
{
printf("Hello, 1!");
printf("Hello, 2!");
printf("Hello, 3!");
return 0;
}
使用编译：
i586-geode-linux-gnu-gcc -g test.c -o testsc
步骤1.在目标上（通过ssh）：
# gdbserver :2345 testsc
Process testsc created; pid = 23623
Listening on port 2345
步骤2.在主机PC上：
chetic@ubuntu:~/Documents/tmp/remotetest$ gdb testsc

Reading symbols from testsc...done.
第3步。我怀疑这是不对的：
(gdb) target remote 192.168.1.102:2345
Remote debugging using 192.168.1.102:2345
Reading symbols from /lib/ld-linux.so.2...(no debugging symbols found)...done.
Loaded symbols for /lib/ld-linux.so.2
0x40000c80 in ?? () from /lib/ld-linux.so.2
第4步：
(gdb) continue
Continuing.
Program received signal SIGSEGV, Segmentation fault.
0x4000f9ef in ?? () from /lib/ld-linux.so.2
(gdb)
我尝试在main设置断点，但没有遇到。如果我在目标上使用gdb运行程序，或者使用常规gcc进行编译并在PC主机上本地运行远程会话，那么一切都可以正常进行调试。
我已经为主机上的目标和主机编译并安装了gdb 7.7和gdbserver 7.7。
谷歌搜索这个问题主要是建议改变堆栈大小，但我尝试使用＆＃39; ulimit -s＆＃39;来改变堆栈大小限制。使用不同的值（包括无限制）并在/ proc / [pid] / maps中看到堆栈受到影响，但问题仍然存在。
记忆地图（此示例使用＆＃39; ulimit -s unlimited＆＃39;）：
# cat /proc/`pidof gdbserver`/maps
