Hello, I am using GCC based build tools, both in Eclipse and VisualGDB, to build for the STM32F7 series, I have set the cpu to cortex-m7 and used the correct STM32F7 port.c/portmacro.h files. In both build enviroments I get the following errors. Can you tell me what is wrong please? Thanks.

Basically - the GCC command line would appear to be wrong as it is
puking on the floating point instructions. You need to specify the
correct architecture and correct FPU on the command line to pass it
floating point instructions.
