Not sure this message is at the right group?  I am trying to compile firmware for a Repeater-Builder DVM - black board (ver 4), using the FAQ in Repeater-Builder.   It referred me to https://github.com/N4IRS/MMDVM-Install/tree/master/STM32-DVM.  I have followed the README.md and I think I have it all in place.  I have not knowingly modified any of the files.  Here is the error that I am getting:
root@pi-star(rw):MMDVM# make -f Makefile.CMSIS

arm-none-eabi-g++ -MMD -mthumb -mlittle-endian -mcpu=cortex-m3 -Wall -I. -ISTM32F10X_Lib/CMSIS/Include -ISTM32F10X_Lib/CMSIS/Device/ST/STM32F1xx/Include -Isystem_stm32f1xx  -DSTM32F105xC -DMADEBYMAKEFILE -DSTM32F1 -Os -flto -ffunction-sections -fdata-sections -g  -nostdlib -fno-exceptions -fno-rtti -c IOSTM.cpp -o obj/IOSTM.o

 #include "stm32f1xx.h"

compilation terminated.

make: *** [Makefile.CMSIS:129: obj/IOSTM.o] Error 1

Any thoughts?  I am trying to get a firmware load to service M17.  Thanks in Advance, Jeff WA3PNY
