Known problems

LTO & debugging on Windows

The Arm 8-2018-q4-major release introduced a problem on Windows: enabling debugging information (-g/-g3) prevents -flto to properly link. For Release configurations it is not a problem to remove the debug
options, but for Debug configurations this is unusable.

The workaround is to revert to the previous 7-2018-q2-update release, or to temporarily disable -flto.

libwinpthread-1.dll

The attempt to fix the LTO plug-in affected the Windows binaries, which in certain configurations may fail with an error claiming the dll is not available. It is, but not in all required folders.

A new release which fixes this bug will be available soon.

The current workaround is to copy the libwinpthread-1.dll from bin to libexec.

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]
