Arduino IDE 1.8.5 install issue?

[DMD-Engineering]

Using Arduino IDE 1.8.5 on Windows 10 system.
Attempting to compile LoRaSender example.
Get the following error:

exec: "C:\Users\DMD\Documents\Arduino\hardware\BSFrance-stm32-master/stm32/tools/win/gcc/bin/arm-none-eabi-g++": file does not exist
Error compiling for board BSFrance LoRaMx boards.

Indeed, the file does not exist in this directory. But it does exist in:
C:\Users\DMD\Documents\Arduino\hardware\BSFrance-stm32-master\stm32\tools\macosx\gcc\bin

I have tried to compile this code on both Mac and Windows install of Arduino IDE and see the same error

Hello,
I also had the same problem today (also using latest Arduino IDE 1.8.5 on Windows 10).

There is an active forum on thethingsnetwork for this board - take a look at the "Big STM32 boards" topic. From there, courtesy of @miwo -
In BSFrance-stm32-master/stm32/tools/win/gcc/bin/arm-none-eabi-g++ stuff is missing.
I copied the contents of gcc-arm-none-eabi-7-2017-q4-major-win32.zip from https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads to here: \hardware\BSFrance-stm32-master\stm32\tools\win\gcc

Next was about the dfu-util-static which was missing:
Downloaded it: http://dfu-util.sourceforge.net/ and put the dfu-util-static.exe here: \hardware\BSFrance-stm32-master\stm32\tools\win

Thanks, that did the trick on the PC ;)

For Mac, I also had to replace the whole gcc folder with the content gcc-arm-none-eabi-7-2017-q4-major-mac.tar.bz2 and install the dfu-utils with brew : brew install libusb
and then brew install dfu-util

Thanks a lot ! I've been searching for few hours how to fix this :)
