Build the Software, Chapter 2

[sulqadari]

Dear Mr. Gay,
kindly ask you to provide me with assistance to overcome step 'Build the Software', chapter 2.
I successfully went through preceding steps exactly the way you mentioned in your Book:

• cygwin installed;
• make and git installed and being recognized by cygwin as a commands;
• stm32 repo successfully cloned;
• libopencm3 cloned (NOTE: I checked out to commit dated oct 12, 2017, otherwise there is additional issue with unrecognized python dir location);
• FreeRTOS unzipped;
• variable FREERTOS assigned with the actual name of the related root folder;
• ARM cross compiller installed and being recognized by cygwin as a command (the lastest version);

But now I stuck at this last but one step (Build the Software).
the cygwin prints the below mentioned log:

codej@DESKTOP-5I7ASE8 /cygdrive/c/Lessons/stm32
$ make
make -C libopencm3 TARGETS=stm32/f1
make[1]: Entering directory '/cygdrive/c/Lessons/stm32/libopencm3'
GENHDR include/libopencm3/efm32/g/irq.json
...
GENHDR include/libopencm3/vf6xx/irq.json
BUILD lib/stm32/f1
/bin/sh: -c: line 0: unexpected EOF while looking for matching `"'
/bin/sh: -c: line 1: syntax error: unexpected end of file
make[1]: *** [Makefile:64: lib/stm32/f1] Error 1
make[1]: Leaving directory '/cygdrive/c/Lessons/stm32/libopencm3'
make: *** [Makefile:38: libopencm3/lib/libopencm3_stm32f1.a] Error 2

Kindly ask you to provide me with assistance.
