Kent... I came across the same error. As vlad had suggested, I tried adding the paths (as shown below) to ugfx/boards/base/STM32F746-Discovery/example_raw32 - which didn't help. It compiled fine when I added the same lines to ugfx\ugfx\boards\base\STM32F746-Discovery . May not be proper way, I hope the higher powers would take a look ;> STMHAL = /home/vlad/Program_Files/ARM_Eclipse/STM32Cube_FW_F7_V1.2.0/Drivers/STM32F7xx_HAL_Driver CMSIS = /home/vlad/Program_Files/ARM_Eclipse/STM32Cube_FW_F7_V1.2.0/Drivers/CMSIS Also you might have to add this to Makefile in the root of the project dir. INCPATH = ./STM32F7xx_HAL_Driver/Inc
