下載gdb-6.8.tar.bz2
http://ftp.cs.pu.edu.tw/Linux/sourceware/gdb/releases/
一.編譯安裝gdb
<1>luther@gliethttp:~/gdb-6.8$ ./configure --target=arm-linux --enable-sim --prefix=/usr/local
<2>luther@gliethttp:~/gdb-6.8$ make
<3>luther@gliethttp:~/gdb-6.8$ sudo make install
二.編譯安裝gdbserver
<1>luther@gliethttp:~/gdb-6.8/gdb/gdbserver$ ./configure --target=arm-linux --host=arm-linux
<2>luther@gliethttp:~/gdb-6.8/gdb/gdbserver$ make
或者make CC=/usr/local/arm-linux/bin/arm-linux-gcc指定編譯器目錄
<3>這樣在gdb-6.8/gdb/gdbserver目錄下就產生了一個gdbserver可執行檔,拷貝到
目標開發板上.
三.測試arm-linux-gdb + gdbserver
在minicom或者putty輸入：[192.168.100.1為pc機ip地址,2345為監聽連接埠]
<1>gdbserver 192.168.100.1:2345 hello
在pc機上輸入：[192.168.100.2為開發板ip地址]
<2>luther@gliethttp:~/ arm-linux-gdb hello 然後輸入
target remote 192.168.100.2:2345
這樣在開發板minicom或putty上可以看到如下提示資訊：
/ # ./gdbserver 192.168.100.1:2345 hello
Process wpa_cli created; pid = 730
Listening on port 2345
Remote debugging from host 192.168.100.1
