Qt Creator 用gdb远程调试问题
问题：Qt Creator 用gdb远程调试不了，提示not in executable format: File format is ambiguous.
Matching formats: elf32-littlearm-symbian elf32-littlearm.
Use "set gnutarget format-name" to specify the format.
原来Qt Creator编译正常，X86上Qt Creator自带的gdb 本地调试没问题。
现在我是想做交叉编译后，在ubuntu上远程调试ARM板上Qt程序。
1.我用命令行:ARM板上用 ./arm-linux-gdb 192.168.10.156:1234 test -qws
ubuntu上用
gdb test
(gdb) target remote 192.168.10.153:1234
Remote debugging using 192.168.10.156:1234
warning: Target-supplied registers are not supported by the current architecture

这样似乎是连上板子上gdb
板子打印出：
Remote debugging from host 192.168.10.153
readchar: Got EOF
Remote side has terminated connection. GDBserver will reopen the connection.
Listening on port 1234
看样子用命令行调试是正常的吧？？？？
2.用Qt Creator
如上图，设置后按开始调试，就是
not in executable format: File format is ambiguous.
Matching formats: elf32-littlearm-symbian elf32-littlearm.
Use "set gnutarget format-name" to specify the format.
不管我GNU目标怎和体系结构怎么选都是不行的，问题何在？？？？？？？？工程有在调试版本模式下编译。
qt gdb 远程调试 --------------------编程问答-------------------- 楼主在板子上装了Qt Creator？ --------------------编程问答--------------------
没有，不是，是PC机ubuntu上，所以才需要远程调试嘛。 --------------------编程问答--------------------
我每次都是用调试的串口，发到minicom上看的 --------------------编程问答--------------------
你没用gdb吧，没用调试工具我也是用串口打印字符串来调试。现在想用gdb远程调试板子。 --------------------编程问答--------------------
还能这样弄呢， 学习了。
是不是就可以设断点什么的了 --------------------编程问答--------------------
是啊，我现在就在学习搞这东东， --------------------编程问答-------------------- 有没有同学用Qt Creator 调试过 Arm啊。。。。。。。 --------------------编程问答-------------------- 难道真那么少人搞这个 --------------------编程问答-------------------- 我现在在Linux 9131-TestMAC-Compile 2.6.32-33-generic-pae #70-Ubuntu SMP Thu Jul 7 22:51:12 UTC 2011 i686 GNU/Linux上面编译gdb，mount到目标机上，
./gdb testmac9131

--------------------编程问答-------------------- 楼主能调试了吗 --------------------编程问答-------------------- 要先在gdb的源码下弄出gdbserver来的，然后在ARM板上运行：
gdbserver 192.168.10.156:1234 app -qws &;
Qt creator中，调试器应该设置为你的arm-linux-gdb;
主机和端口号为你的板子的IP和端口号;
体系结构是arm;
GNU目标是arm-none-linux-gnueabi
补充：移动开发 , Qt
