Purpose

This set of scripts will build the requisites for KLayout builds with MSVC 2017, both for 32 and 64bit. These are:

• libexpat: XML parser for use with Python standalone modules
• libcurl: HTTP/HTTPS access for Python standalone tools
• zlib: Compression library
• python: A basic installation including a debug variant
• ruby: Basic Ruby required to support DRC and other DSL's
• openssl: Support for HTTPS

Requirements

• git installed in PATH
• MSVC 2017 installed (e.g. community edition). Or MSVC2019 with compiler 14.1.
• Helper tools: (1) ruby.exe, bison.exe, flex.exe, sed.exe in PATH (2) cmake.exe in PATH (3) perl (for OpenSSL, Windows version) (4) nasm (for OpenSSL) (5) host Python (for Python)

For (1) use MSYS2:

• install "pacman -S ruby bison flex sed"
• set PATH=c:\msys64\usr\bin;%PATH%

For (2) use cmake for Windows: https://cmake.org/files/v3.12/cmake-3.12.1-win64-x64.msi

• set "PATH=c:\Program Files\cmake\bin;%PATH%"

For (3) use Strawberry Perl from http://strawberryperl.com

• set "PATH=c:\strawberry\perl\bin;%PATH%"

For (4) use NASM from https://www.nasm.us

• set "PATH=c:\Program Files\NASM;%PATH%"

For (5) use Anaconda3 from https://repo.anaconda.com/archive/Anaconda3-2021.05-Windows-x86_64.exe

• set anaconda=c:\ProgramData\Anaconda3
• set "PATH=%anaconda%;%anaconda%\Library\mingw-w64\bin;%anaconda%\Library\usr\bin;%anaconda%\Library\bin;%anaconda%\Scripts;%anaconda%\bin;%PATH%"

Note: cmake and perl must be taken from the Windows installation! Make sure they are in the path before MSYS2 components.

Script Usage

Set TEMP environment variable to a suitable build directory.

To build all:

buildall.bat -t <installation dir>

To build 32 bit only:

buildall.bat -32 ...
