[MSYS2] Unable to build Zephyr

[SebastianBoe]

Hi,

following the installation instructions I was unable to build Zephyr using MSYS2.

The error I get is:

sebo@SEBO-WIN MINGW64 ~/zephyr/samples/hello_world/build
$ cmake -GNinja -DBOARD=nrf52_pca10040 ..
CMake Deprecation Warning at C:/msys64/home/sebo/zephyr/cmake/app/boilerplate.cmake:37 (cmake_policy):
The OLD behavior for policy CMP0000 will be removed from a future version
of CMake.

The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.

I added some debug prints to inspect the path that is corrupted:

message( "${ZEPHYR_BASE}/VERSION")
file(READ ${ZEPHYR_BASE}/VERSION ver)
message( "${ZEPHYR_BASE}/VERSION")

I can't explain that "file(READ [...])" is prefixing the file with "/home/sebo/zephyr/samples/hello_world/"

You need to use a version of Ninja natively compile for MSYS2, I've updated the doc to reflect this.

Also from your log it seems you are on a MinGW shell, which will not work. As described in the build instructions you need to open an MSYS2 MSYS shell.
