Version v8.2.1-1.4 20190214 is a maintenance release of GNU MCU Eclipse ARM Embedded GCC that fixes the bugs affecting Windows LTO builds, present in the previous release.
This release follows the official
GNU Arm Embedded Toolchain
8-2018-q4-major release from December 20, 2018 and it is based on the
gcc-arm-none-eabi-8-2018-q4-major-src.tar.bz2 source invariant.
Compared to the ARM distribution, the build procedure is more or less the same and there should be no functional differences, except the following bug fixes:
- a patch was applied to binutils to fix the 32-bit objcopy bug 24065
- GDB was built the Git commit ad0f979c9 from 2019-01-29, to fix the bugs affecting C++ LTO projects 24145
by default, the GCC build script fails to create
liblto_plugin-0.dllfor static builds with mingw; code to create the plugin was added
liblto_plugincopied/linked to the
arto find it and be able to process archives with LTO objects
- a patch was applied to gcc to fix the Windows LTO with -g bug 89183
- a patch was applied to gcc to fix the Windows paths with spaces bug 89249
Binaries for Windows, macOS and GNU/Linux are provided.
The GNU/Linux binaries were built on two CentOS 6 Docker images (32/64-bit), and run on any distribution based on CentOS 6 or later.
The macOS binary was built on a macOS 10.10.5 and must run on any newer macOS system.
The Windows binaries were built with mingw-w64, and run on any reasonably recent i686 and x86_64 Windows machines.
Instructions on how to install the binaries are available in the How to install the ARM toolchain? page.
$ xpm install --global @gnu-mcu-eclipse/arm-none-eabi-gcc
This installs the latest available version.
For better control and repeatability, the build scripts use Docker containers; all files required during builds are available as a separate gnu-mcu-eclipse/arm-none-eabi-gcc-build project.
- LTO is still not functional on Windows.
