Issue Compiling the Tool Suite on Windows 10

[Luke Halberstadt]

Dear Sir/Madam,

I am working on compiling the RTEMS toolchain on a Windows machine following the instructions provided here:
https://docs.rtems.org/branches/master/user/hosts/windows.html#cygwin

Both Cygwin and MSYS2 are installed along with most of the recommended packages, however, I could not find the gcc4* or python packages. Instead, I installed similar gcc* and python2 packages.

When I compile using the following command,
../source-builder/sb-set-builder --prefix=/cygdrive/c/opt/rtmes/5.1 5/rtems-sparc --jobs=none

The build makes it up to building gdb and then fails with a python error.
building: sparc-rtems5-gdb-9.1-x86_64-pc-cygwin-1
error: building sparc-rtems5-gdb-9.1-x86_64-pc-cygwin-1

I have attached the rsb-report and log files The key issue seems to be in the following lines of the report:
checking whether to use python... /usr/bin/python2
checking for python... no
configure: error: no usable python found at /usr/bin/python2
make[1]: *** [Makefile:8869: configure-gdb] Error 1
make[1]: Leaving directory '/cygdrive/c/opt/rtems/5.1/rtems/build/sparc-rtems5-gdb-9.1-x86_64-pc-cygwin-1/build'
make: *** [Makefile:855: all] Error 2
shell cmd failed: sh -ex  /cygdrive/c/opt/rtems/5.1/rtems/build/sparc-rtems5-gdb-9.1-x86_64-pc-cygwin-1/do-build
error: building sparc-rtems5-gdb-9.1-x86_64-pc-cygwin-1

By default, Python is installed at /bin, not /usr/bin, so I tried copying the python files from /bin to /usr/bin, but that did not resolve the issue. I attached a screenshot showing the contents of /usr/bin when this failure occurred.

Any ideas how to get around this problem so that gcc recognizes the python installation? Thank you for your input.
