	I have a project which compiled fine about a year ago. I neede to do some changes, but discovered that the original source will no longer compile. The error message look like this: Compiling 'AuDa_HD' for 'Adafruit SAMD (32-bits ARM Cortex-M0+ and Cortex-M4) Boards' arm-none-eabi-g++: error: missing argument to -mcpu= arm-none-eabi-g++: warning: -x c++ after last input file has no effect arm-none-eabi-g++*: fatal error: no input files compilation terminated An error was encountered during the 'Deep Search' library discovery process. Build failed for project 'AuDa_HD' I have no idea where to begin to troubleshoot. Any help would be very welcome ! Dave Long

	Thanks for the report. If you could ensure the below options are set in vMicro: vMicro > Compiler > Verbose vMicro > Compiler > Show Build Properties Then perform Build > Clean Then perform a Build as normal And attach the full output from the Output Window > Micro Build as a *.txt file, we will be able to assist further. If it is also possible to also email us the project it will ensure we can resolve this as quickly as possible.

	The output is still the same. See attached txt file. I will send you the project in reply to the mail I just received

	OOPS! - sorry guys, I have discovered that my project was on an Adafruit M0 board, NOT a SAMD type - once I selected the correct board type it compiled correctly again ! Sorry for the 'beginners mistake' - I'm only 63 years old, and started programming when I was 17 - I guess I never learn! Dave Long
