Hello, I had similar problems.
By default, the STM32 makefile downloads the latest version of the periphlib (1.3) which is not the one David originally coded to (1.1). The difference is that you have to edit the stm32f4xx.h file in the peripheral lib, as mentioned in the error: STM32F4xx_DSP_StdPeriph_Lib_V1.3.0/Libraries/CMSIS/Device/ST/STM32F4xx/Incl > ude/stm32f4xx.h:101:3: error: #error "Please select first the target > STM32F4xx device used in your application (in stm32f4xx.h file)" and also in the updated README of codec2/stm32. Cheers.
