GDB (символический отладчик GNU) — это просто инструмент отладки. Это бесплатное программное обеспечение, защищенное Стандартной общественной лицензией или GPL.

Как и все отладчики, GDB позволяет вам отлаживать программу, включая остановку программы там, где вы хотите, после чего вы можете просматривать переменные, регистры, память и стек. Кроме того, вы можете изменять переменные и значения памяти. GDB — очень мощный отладчик, он может отлаживать несколько языков. Здесь мы занимаемся отладкой только C и C ++, а не других языков. Следует также отметить, что GDB — это отладчик, а не интегрированная среда, такая как VC. Вы можете использовать некоторые внешние инструменты, такие как XXGDB, DDD и т. Д. Все они имеют графический интерфейс, поэтому им удобнее пользоваться, но они всего лишь оболочка GDB. Следовательно, вы все равно должны быть знакомы с командами GDB. Фактически, когда вы используете эти графические интерфейсы в течение длительного времени, вы обнаружите важность знакомства с командами GDB.

Среда отладки GDB встроенного Linux состоит из двух частей: хоста (ПК) и цели (ARM). Хост использует инструмент отладки arm-linux-gdb, а цель должна запускать gdbserver. Эти две части могут быть подключены через последовательный порт или Подключитесь к сетевому порту и верните выполнение приложения ARM на стороне Target хосту. Команда трассировки отладки выдается из arm-linux-gdb на стороне хоста. Следовательно, вам нужна перекрестная отладка GDB.

Вы можете загрузить соответствующую версию GDB с http://ftp.gnu.org/gnu/gdb/. Последняя версия — gdb-9.1.tar.xz. Я использую еще 8.2, поэтому скомпилированная версия — 8.2

Для компиляции исходного кода нам также необходимо установить MSYS

arm-linux-gnueabihf-gdb versus gdb-multiarch

I’m trying to perform cross platform remote debugging from my x86 computer to a remote ARM device. (ex: Beagle Bone Black) I’m using Ubuntu 14.04 and Eclipse CDT. I installed the package gcc-arm-linux-gnueabihf but the gdb debugger is not in that package. (http://packages.ubuntu.com/precise/gcc-arm-linux-gnueabihf) Therefore, I’m wondering if I should use the Linaro toolchain (which include arm-linux-gnueabihf-gdb) or if I should install the gdb-multiarch package. What is the difference between gdb-multiarch and arm-linux-gnueabihf-gdb ? Is it better to use gdb-multiarch ? ssinfod

I received an answer from the linaro mailing list:

For Ubuntu hosts from 12.04 onwards, gdb-multiarch is used as gdb client for debugging. As name indicates it is a common client to any architecture and not restricted to ARM.

Generally, all gdb clients are architecture independent because architecture specific part is handled in gdbserver itself. So, other than the name arm-linux-gnueabihf-gdb, I am guessing it is same as gdb-multiarch.

I received another answer from the linaro mailing list:

The Linaro gdb release will generally be more up to date than the Ubuntu one. For example our latest release is 7.8, and that is only available in utopic, not trusty so if you plan to use an Ubuntu LTS release it might be better to use the Linaro shipped gdb. Linaro gdb also contains fixes and improvements that aren’t in the upstream stable branch. Historically Ubuntu has often picked these changes up too but that may not always be the case.

gdb-multiarch obviously supports a range of other architectures besides ARM, so if that is something that would be useful for you then it might make sense to use that.
