This release follows the official
GNU Arm Embedded Toolchain
8-2019-q3-update release from July 10, 2019 and it is based on the
gcc-arm-none-eabi-8-2019-q3-update-src.tar.bz2 source invariant.
For more details see the original Arm release text files:
The supported libraries are:

Due to a bug in the build scripts, the Windows
gdb-pyhad a hard-wired dependency to Python 2.7.13 and failed to start on other versions; fixed;
Due to a bug in the build scripts, the macOS
gdb-pyhad a wrong dependency and failed to start; fixed;
Due to a bug in the build scripts, the Windows binaries included two
copies of the
docsfolder, one in root and one in the
sharefolder; the script was fixed and now there is only one copy in
Due to an omission in the build scripts, the content of the
libgcovlibrary was mostly empty; the script was fixed and now the library has the expected content.
There should be no functional changes.
To improve LTO support, the
lib/bdf-plugins folder was added, with
a link to the
liblto_plugin.so library (a file copy on Windows).
This allows the use of traditional program names, like
instead of the new
arm-none-eabi-gcc-ar, without getting errors like:
arm-none-eabi-ar -r "libarm-static-lib.a" ./lib.o arm-none-eabi-ar: creating libarm-static-lib.a arm-none-eabi-ar: ./lib.o: plugin needed to handle lto object <---
The issue was reported to Arm as bug 1838049.
Partial experimental support for Python 3 was added to GDB for GNU/Linux and macOS; not yet available on Windows (24469).
arm-none-eabi-gdb-pyfails to start on Ubuntu (and possibly other Debian) systems, it fails with a message like:
$ PYTHONHOME=/usr PYTHONPATH=/usr/lib/python2.7 arm-none-eabi-gdb-py --version Traceback (most recent call last): File "/usr/lib/python2.7/site.py", line 554, in <module> main() File "/usr/lib/python2.7/site.py", line 536, in main known_paths = addusersitepackages(known_paths) File "/usr/lib/python2.7/site.py", line 272, in addusersitepackages user_site = getusersitepackages() File "/usr/lib/python2.7/site.py", line 247, in getusersitepackages user_base = getuserbase() # this will also set USER_BASE File "/usr/lib/python2.7/site.py", line 237, in getuserbase USER_BASE = get_config_var('userbase') File "/usr/lib/python2.7/sysconfig.py", line 587, in get_config_var return get_config_vars().get(name) File "/usr/lib/python2.7/sysconfig.py", line 533, in get_config_vars _init_posix(_CONFIG_VARS) File "/usr/lib/python2.7/sysconfig.py", line 417, in _init_posix from _sysconfigdata import build_time_vars File "/usr/lib/python2.7/_sysconfigdata.py", line 6, in <module> from _sysconfigdata_nd import * ImportError: No module named _sysconfigdata_nd
The problem is caused by gdb-py not being able to locate the Python system libraries, split into multiple packages and installed in multiple folders.
The workaround is to pass the Python environment to gdb-py:
PYTHONPATH="$(python -c 'import os; import sys; print(os.pathsep.join(sys.path))')" \ PYTHONHOME="$(python -c 'import sys; print(sys.prefix)')"

Binaries for Windows, macOS and GNU/Linux are provided.
The binaries were built using the xPack Build Box (XBB), a set of build environments based on slightly older distributions, that should be compatible with most recent systems.
- GNU/Linux: all binaries were built with GCC 7.4, running in a CentOS 6 Docker container
- Windows: all binaries were built with mingw-w64 GCC 7.4, running in a CentOS 6 Docker container
- macOS: most binaries were built with GCC 7.4, running in a separate folder on macOS 10.10.5; GDB cannot be compiled with GCC, so Apple clang was used.
The binaries were testes on Windows 10 Pro 32/64-bit, Ubuntu 18 LTS 64-bit, Xubuntu 18 LTS 32-bit and macOS 10.13.
The tests consist in building and debugging some simple Eclipse projects available in the project.
Since the source code used for GCC is identical to the one used by Arm, the long and complex tests performed by Arm to validate their release were not executed again.
