Polyglot-and-PyICU-fix-Win10

Instructions to get Polyglot, PyICU and Pycld2 to build on Windows 10.

1. You need ICU. There are quite a few ways of getting ICU onto your computer. Make sure you have the icu/bin in your path as well.

   • Anaconda (This is the fastest method)
     • conda install -c conda-forge icu=58.1
     • https://anaconda.org/conda-forge/icu
   • Download the Binaries and the Source from ICU's main site: http://site.icu-project.org/
     • If you are building from VS2015, make sure you have updated it with patches 1 & 2
     • Update it from "Tools > Extensions & Updates..."
     • Check the Readme.html on how to test whether it works inside the ICU file
   • Online precompiled binaries
     • https://www.npcglib.org/~stathis/blog/precompiled-icu/

2. PyICU. This is part needs more effort and there are a few things you need to change:

   • Download the 7z file for PyICU and try to build. python setup.py build

   This error here was an absolute NIGHTMARE:

      ICU_VERSION = subprocess.check_output(('icu-config', '--version')).strip()
      AttributeError: 'module' object has no attribute 'check_output'
   

   • To fix this, change that line in setup.py (in the PyICU folder) to:

     • ICU_VERSION = subprocess.check_output(('icuinfo', '--version')).strip()
       • Windows does not have 'icu-config', it's 'icuconfig'

   • Change the following lines and put in your icu path (E.g. 'C:/icu'):

     1. INCLUDES: 'win32': ['C:/icu/include'],
     2. LFLAGS: 'win32': ['C:/icu/lib'],

   • If you have more errors:

     • calendar.cpp error:

       • A very quick fix would be to comment out all lines that threw an error. There's something wrong with daylight. For me it was (362, 376, 381, 389)
       • This link here explains why: ovalhub/pyicu#7
       • There is a fix here, but I didn't try it.

     • common.cpp error:

       • Replace: u_memcpy(PyUnicode_2BYTE_DATA(result), utf16, len16);
       • with: u_memcpy((UChar *) PyUnicode_2BYTE_DATA(result), utf16, len16);
       • This is to explicitly cast it

     • if you still have problems: There is a .whl you can use. Extract it in the folder which contains setup.py https://github.com/ovalhub/pyicu/files/829179/PyICU-1.9.5-cp36-cp36m-win_amd64.whl.zip

3. Pycld2:

   • You will most likely have problems installing this file if you updated and patched Visual Studios.
     • bindings\pycldmodule.cc(16): fatal error C1083: Cannot open include file: 'cstrings': No such file or directory
     • This is the <string.h> error:
       • In 'pycld2-0.31\bindings\pycldmodule.cc'
         • Replace <string.h> with
       • In 'pycld2-0.31\bindings\encodings.cc'
         • Replace <string.h> with
         • Replace strcomp with _stricmp

✨ It should build successfully after this! :) ✨
