[STM32F7 Discovery]

I have upgraded my toolchain from GNU Tools ARM Embedded 4.9.3 to GNU Tools ARM Embedded 5.2.4. I edited the PATH in Eclipse to first list the GNU toolchain and then Cygwin. I am still getting the following errors:

Program "gcc" not found in PATH

Program "g++" not found in PATH

Eclipse says these errors are a "C/C++ Scanner Discovery Problem" and points me to the location "Project Properties, C++ Preprocessor Include/Providers, [CDT GCC Built-in Compiler Settings] options". 

This is the same error that I had before with the 4.9.3 toolchain in Eclipse. For some reason when I try to compile in the Cygwin terminal, I get the other error of not recognizing cortex-m7.

To clarify, does this refer to the GNU Tools ARM Embedded download mentioned by CShark? Or to cygwin?

I have followed the steps in the previous post and am getting the following error:

This seems to be set in the Makefile included in the zipped project above:

# MCU flags
MCUFLAGS      = -mthumb -mcpu=cortex-m7

 

Does this need to be changed or am I missing something?

I believe I have applied all of the suggestions recommended in this thread, but I am not sure how to use cygwin's mkdir in Eclipse. I keep getting errors saying "recipe for target 'build/obj/../uGFX/src/gfx.o' failed", and that "Program "gcc" not found in PATH".

Sorry for all the duplicate posts. I kept getting an error when I tried to submit it the first time and I didn't think it went through.

Joel,

Is the example project you provided earlier in this thread still available? I have not been able to find it after the switch to "community.ugfx.org" took place a few days ago. It does not appear to be attached to your earlier post now.

[[FEATURE] Added the ability to compile ugfx as a single file]

Can you clarify how one would use this to compile onto an Arduino platform? I have read through most of the uGFX documentation but could not find anything about this. I am trying to use an Arduino Due + uGFX to host an embedded GUI for a senior project at my university.
