If you enjoyed this guide, feel free to follow me on Twitter where I tweet about C++ and other interesting low level topics. That's it! We now have a dev playground which lets us compile, disassemble, execute, and debug ARM64 binaries so we can experiment and learn about the ARM64 architecture. There's many other resources for learning GDB, so I won't go into detail here. libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev. In Ubuntu cases: sudo apt-get install -y build-essential libssl-dev zlib1g-dev libbz2-dev. Follow this answer to receive notifications. A third option that I use and particularly like is to use pyenv, which is a simple Python Version Management. We can do this with aarch64-linux-gnu-objdump which we got with the toolchain. try this first: sudo apt-get install libc6-dbg gdb valgrind. We're interested in learning the ARM64 architecture, so it's important to be able to disassemble binaries, so we can see the ARM64 instructions that it contains. The above procedure will install the debug symbol package for a single package only. Run the following command in the terminal: sudo apt install gcc gdb -y. Install prerequisite GN packages for compiling and debugging. Note: The commands discussed in this article have been tested on Ubuntu 20.04 LTS (Focal Fossa). Automatic Resolution / Installation of necessary packages. Ubuntu 20.04 system User with sudo privileges for renaming multiple files. or sudo apt-get install xserver-xorg-core-dbgsym.

Done Building dependency tree Reading state information. Generating static binaries is an easy way around this, since we're just playing around.Ĭool! Now we have an ARM64 binary we can disassemble, execute, and debug. If the package in question is the xserver-xorg-core package you can try sudo apt-get install xserver-xorg-core-dbg. sudo apt-get install libc6-dbg gdb valgrind Share Improve this answer answered Jun 4 '14 at 10:26 undy 191 8 got this when i ran the command.Reading package lists. We need this because the cross compiler by default generates dynamic binaries that rely on an ARM64 version of the dynamic linker, which we don't have. $ aarch64-linux-gnu-g++-8 -o arm64main arm64main.cpp -staticĪrm64main: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0, BuildID=7b1bbf64436de3f0e268d1d8ab93d2123d4dcaef, not stripped
