Python for Windows ARM32
2+
=================================
3+
.. contents::
4+
5+
Prerequisites
6+
-------------
7+
8+
- `Microsoft Visual Studio 2017 <https://visualstudio.microsoft.com/downloads/>`_ (tested with version 15.9.4)
9+
- `Git for Windows <https://git-scm.com/downloads>`_
10+
- Perl 5 (for OpenSSL Configure)
11+
- `CPython 3.5 or newer (add Python to the path) <https://www.python.org/>`_
12+
13+
Get the CPython on Windows ARM32 code
14+
------------
15+
16+
Check out the Windows ARM32 code for CPython and populate the external dependencies::
17+
18+
git clone https://github.com/ms-iot/cpython.git
19+
cd cpython
20+
git checkout win-arm32-master
21+
.\PCbuild\get_externals.bat
22+
23+
Get OpenSSL for Windows ARM32
24+
-----------------------------
25+
26+
Build OpenSSL binaries for Windows ARM32::
27+
28+
cd ..
29+
git clone https://github.com/openssl/openssl.git
30+
cd openssl
31+
git checkout -b win-arm32 OpenSSL_1_1_0i
32+
33+
Start a build environment with vcvarsamd64_arm.bat and apply required patch::
34+
35+
cmd /k "C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Auxiliary\Build\vcvarsamd64_arm.bat"
36+
37+
REM apply patch required for successful ARM32 build
38+
git am < ..\cpython\tools\winiot\OpenSSL-for-Windows-ARM32.patch
39+
40+
41+
When running ``perl Configure`` ignore this error::
42+
43+
It looks like you don't have either nmake.exe or dmake.exe on your PATH,
44+
so you will not be able to execute the commands from a Makefile. You can
45+
install dmake.exe with the Perl Package Manager by running:
46+
ppm install dmake
47+
48+
| Configure the OpenSSL makefile for Windows ARM32
49+
Run ``nmake`` to build OpenSSL::
50+
51+
perl Configure VC-WIN32 no-asm
52+
nmake
53+
54+
Exit cmd.exe started with ``cmd /k`` above::
55+
56+
exit
57+
58+
Copy OpenSSL files for Windows ARM32 to cpython externals::
59+
60+
md ..\cpython\externals\openssl-bin-1.1.0i\arm32\include\openssl
61+
copy LICENSE ..\cpython\externals\openssl-bin-1.1.0i\arm32
62+
copy include\openssl\*.h ..\cpython\externals\openssl-bin-1.1.0i\arm32\include\openssl
63+
copy ms\applink.c ..\cpython\externals\openssl-bin-1.1.0i\arm32\include
64+
copy *.lib ..\cpython\externals\openssl-bin-1.1.0i\arm32
65+
copy libcrypto-1_1.dll ..\cpython\externals\openssl-bin-1.1.0i\arm32
66+
copy libcrypto-1_1.pdb ..\cpython\externals\openssl-bin-1.1.0i\arm32
67+
copy libssl-1_1.dll ..\cpython\externals\openssl-bin-1.1.0i\arm32
68+
copy libssl-1_1.pdb ..\cpython\externals\openssl-bin-1.1.0i\arm32
69+
70+
Return to the Python clone root::
71+
72+
cd ..\cpython
73+
74+
Build CPython and stage files for xcopy install
75+
-----------------------------------------------
76+
77+
Building using Tools\winiot\build.bat requires CPython 3.5 or greater to be on the path.
78+
79+
To build a retail image::
80+
81+
Tools\winiot\build.bat -arm -r -c
82+
83+
To build a debug image with test files::
84+
85+
Tools\winiot\build.bat -arm -r -c -d -t
86+
87+
Copy debug files to Windows IoT Core device and run tests
88+
---------------------------------------------------------
89+
90+
Map a drive and copy the files::
91+
92+
net use Q: \\<device ip address>\c$ /user:\administrator
93+
robocopy /S PCbuild\iot\arm32\Debug\ Q:\pythond
94+
95+
Connect via `ssh <https://docs.microsoft.com/en-us/windows/iot-core/connect-your-device/ssh>`_ and run the standard library tests::
96+
97+
ssh administrator@<device ip>
98+
99+
set PATH=%PATH%;c:\pythond;c:\pythond\scripts
100+
set PYTHONHOME=c:\pythond
101+
102+
REM fix case of TEMP directory variable for tests
103+
set TEMP=C:\Windows\Temp
104+
105+
REM Run tests
106+
python_d -m test -j3
107+
108+
REM Run ssl tests with network resources enabled
109+
python_d -Werror -bb -m test -u urlfetch -u network -v test_ssl
110+
111+
Copy release files to device
112+
----------------------------
113+
114+
Map a drive and copy the files::
115+
116+
net use Q: \\<device ip address>\c$ /user:administrator
117+
robocopy /S PCbuild\iot\arm32\Release\ Q:\python
118+
119+
Connect via `ssh <https://docs.microsoft.com/en-us/windows/iot-core/connect-your-device/ssh>`_ and test install::
120+
121+
ssh administrator@<device ip>
122+
123+
set PATH=%PATH%;c:\python;c:\python\scripts
124+
set PYTHONHOME=c:\python
125+
126+
python -c "print ('Hello, ARM32!')"
127+
128+
Installing pip
129+
--------------
130+
131+
To install pip run the ensurepip module and then check for upgrades::
132+
133+
python -m ensurepip
134+
python -m pip install --upgrade pip
