Compiling gdb for remote debugging

I am trying to remotely debug an application running on arm9

So far, I have managed to cross-compile and run gdbserver on my device.

  • get gdb (7.2) sources and extract them
  • ./configure --target = arm-none-linux-gnueabi --with-expat = / usr / local / lib /
  • make
  • cd gdb / gdbserver
  • ./configure --host = arm-none-linux-gnueabi
  • make
  • tftp gdbserver on my device
  • start and connect via gdb to the device

gdbserver "seems" to start correctly and join my helloworld application

When I try to run gdb on a remote server, I get the msgstr "warning: cannot parse the XML description of the target; XML support was disabled at compile time

Obviously, compilation did not take expat into account. I'm really not sure how to specify the expat library path to the script configuration.

(old question, but I stumbled upon it using a search on the same issue)

The problem is the lack of "expat" lib. This is hard to guess because:

  • this library is optional for compiling gdb
  • The name "expat" does not have a clear XML connection ...

So install "expat-dev" (with your package manager or something else) and then restart. / configure. Be careful to install the version of "dev" as we are recompiling and you need include files.

To be sure, you can add "-with-expat" to the call. / configure so that it stops with an error if expat is not found.

Somehow it all worked

Alternatively, create the ~ / .gdbinit file with

file /home/username/path/to/exec/exec_name set sysroot /path/to/libraries/running/on/target/device target remote HOST:PORT b main
