I got into the book "Beginning STM32" - Warren Gay. I tried to build the sources under Cygwin, but even if the path to the required files is denoted in the makefile, the required files were not found.The file in the folders libopencm3/cm3/scb.h lays in the path: /home/root/STM32/stm32f103c8t6/libopencm3/include so the correct path should be /home/root/STM32/stm32f103c8t6/libopencm3/include/libopencm3/cm3/scb.h and I checked the presence of the files.
So I tried to change the #include into #include "file.h" with the required header file in the source folder - this worked, but there are a lot of cases in different source files.
Is there any suggestion to get this fixed or to find a way to get out of this?
Thanks a lot!
This is what I got from the terminal.

So, I know what is the source of the problem. There are problems in Cygwin with the path format or rather between the interaction between the Windows and Linux path formats. I could solve the problem by changing the paths in the Makefile from the Linux /home/folder to the Windows D:\home\folder\ format.
