[Embedded] How to Cross Compile GNU Project Debugger

0.assume that your toolchain is

arm-linux-gcc
arm-linux-g++
arm-linux-ar
arm-linux-ld
arm-linux-as
arm-linux-strip
...

and under your PATH

1.download termcap

$ wget ftp://ftp.gnu.org/gnu/termcap/termcap-1.3.1.tar.gz

2.configure termcap

$ ./configure --target=arm-linux --prefix=/path/to/install/termcap

3.modify Makefile

$ vim Makefile

-CC = gcc
-AR = ar
-RANLIB = ranlib
+CC = arm-linux-gcc
+AR = arm-linux-ar
+RANLIB = arm-linux-ranlib

4.install

$ make && sudo make install

5.download GDB

$ wget ftp://ftp.gnu.org/gnu/gdb/gdb-6.7.1.tar.gz

6.configure GDB

$ env CPPFLAGS=-I/path/to/install/termcap/include LDFLAGS=-L/path/to/install/termcap/lib ./configure --target=arm-linux --prefix=/path/to/install/gdb

7.if error has occurred like this:

cc1: warnings being treated as errors

8.modify Makefile

$ vim Makefile

-CC = gcc
-CXX = g++
+CC = arm-linux-gcc
+CXX = arm-linux-gcc++

9.make & check

$ make && make install
$ file /path/to/install/gdb/bin/gdb: ELF 32-bit LSB executable, ARM, version 1 (SYSV), for GNU/Linux 2.6.27, dynamically linked (uses shared libs), not stripped

/** install gdb-7.3.1 @ 2011-12-14 **/
1.get source

wget http://ftp.gnu.org/gnu/gdb/gdb-7.3.1.tar.gz
wget ftp://ftp.gnu.org/gnu/termcap/termcap-1.3.1.tar.gz

2.configure termcap

$ ./configure --target=arm-linux --prefix=/path/to/termcap
$ make && sudo make install

3.configure gdb & gdbserver

$ cd gdb-7.3.1
$ env CPPFLAGS=-I/path/to/termcap/include LDFLAGS=-L/path/to/termcap/lib ./configure --target=arm-linux
$ make
$ file gdb/gdb
gdb/gdb: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.27, not stripped
$ file gdbserver
