Known problems

GDB

The GDB binary supplied with this release has problems loading the symbols from applications compiled with -flto, it will either crash with segmentation fault or throw an assert.

The bug reports:

• https://sourceware.org/bugzilla/show_bug.cgi?id=24145 (to the GDB maintainers)
• https://bugs.launchpad.net/gcc-arm-embedded/+bug/1813553 (and to the Arm maintainers)

The current workaround is to use the GDB binary provided in the previous v7.x release.

liblto_plugin

The tools from binutils, like the archiver, require a plugin in order to process files compiled with -flto (for example to create a static library). The GNU/Linux and macOS distributions include the liblto_plugin.so file, it just needs to be linked to the lib/bfd-plugins folder. The Windows distribution does not include the liblto_plugin-0.dll file, and it must be copied from the ARM distribution.

Easy install

The toolchain is also available as an xPack and can be conveniently installed with xpm:

$ xpm install --global @gnu-mcu-eclipse/arm-none-eabi-gcc 

To install exactly this version, use:

$ xpm install --global @gnu-mcu-eclipse/[email protected]
