klayout/macbuild

Relevant KLayout version: 0.25.1

1. Introduction

This directory "macbuild" contains different files required for building KLayout (http://www.klayout.de/) version 0.25 or later for different Mac OSXs including:

• Yosemite (10.10)
• El Capitan (10.11)
• Sierra (10.12)
• High Sierra (10.13)

By default, Qt framework is "Qt5" from Mac Ports (https://www.macports.org/) which is usually located under:

/opt/local/libexec/qt5/

IMPORTANT

* Please DO NOT USE "Qt 5.10.0" which is problematic in showing your design in the main canvas.
* Please USE "Qt 5.9.x" instead (5.9.3 is recommended).
* Building with Qt4 will lead to some compile errors.

Also by default, supported script languages, i.e, Ruby and Python, are those standard ones bundled with the OS.

2. Non-OS-standard script language support

You may want to use a non-OS-standard script language such as Python 3.6 from Anaconda2 (https://www.anaconda.com/download/#macos) in combination with KLayout.

Since Anaconda2 is a popular Python development environment, this is worth trying. Unfortunately, however, some dynamic linkage problems are observed as of today. On the other hand, Python 3.6 provided by Mac Ports is usable. Please try this (refer to 3B below) if you feel it's useful.

3. Use-cases

3A. Debug build using the OS-standard script languages

1. Make a symbolic link from the parent directory (where 'build.sh' exists) to 'build4mac.py', that is,

  build4mac.py -> macbuild/build4mac.py

2. Invoke 'build4mac.py' with appropriate options ("-d" for debug build):

$ cd /where/'build.sh'/exists
$ ./build4mac.py -d

3. Confirm successful build.
4. Run 'build4mac.py' again with the same options used in 2. PLUS "-y" to deploy executables and libraries (including Qt's frameworks) under "klayout.app" bundle. The buddy command line tools (strm*) will also be deployed.

$ ./build4mac.py -d -y

5. Copy/move generated bundles ("klayout.app" and "klayout.scripts/") to your "/Applications" directory for installation.

3B. Release build using the non-OS-standard Ruby 2.4 and Python 3.6 both from MacPorts

1. Make a symbolic link from the parent directory (where 'build.sh' exists) to 'build4mac.py', that is,

build4mac.py -> macbuild/build4mac.py

2. Invoke 'build4mac.py' with appropriate options:

$ cd /where/'build.sh'/exists
$ ./build4mac.py -r mp24 -p mp36

3. Confirm successful build.
4. Run 'build4mac.py' again with the same options used in 2. PLUS "-Y" to deploy executables and libraries under "klayout.app" bundle. The buddy command line tools (strm*) will also be deployed.

$ ./build4mac.py -r mp24 -p mp36 -Y

• [-Y|--DEPLOY] option deploys KLayout's dylibs and executables only. That is, paths to other modules (Ruby, Python, and Qt5 Frameworks) remain unchanged (absolute paths in your development environment).

5. Copy/move generated bundles ("klayout.app" and "klayout.scripts/") to your "/Applications" directory for installation.

4. Making a DMG installer

You can make a DMG installer using another Python script 'makeDMG4mac.py'. This script requires a directory generated by 'build4mac.py' with [-y|-Y] option (refer to 3A.4 & 3B.4)

1. Make a symbolic link from the parent directory (where 'build.sh' exists) to 'makeDMG4mac.py', that is,

makeDMG4mac.py -> macbuild/makeDMG4mac.py

2. Invoke 'makeDMG4mac.py' with -p and -m options, for example,

$ cd /where/'build.sh'/exists
$ ./makeDMG4mac.py -p qt5.pkg.macos-HighSierra-release -m

5. Alternative building options

5.1 Python 3.6 from brew, Qt 5.10.1 from brew

Homebrew's installation of python3 (brew install python3) places a Python.framework in /usr/local/opt/python/Frameworks/Python.framework/, which you can use to build KLayout from. Qt can also be downloaded from brew with brew install qt.

# Build step
./build4mac.py -p B36 -q Qt5Brew

# Deploy step
./build4mac.py -p B36 -q Qt5Brew -y  # normal deploy
./build4mac.py -p B36 -q Qt5Brew -y -v 3 2>&1 | tee qt5.pkg.macos-HighSierra-release.log  # deploy with debug options

# Packaging step
./makeDMG4mac.py -p qt5.pkg.macos-HighSierra-release -m -q Qt5101

Known issues

Because we link python to /usr/local/opt/python/Frameworks/Python.framework/, updating python from brew might break klayout if the new version is incompatible. To fix this, it is better to link python directly to /usr/local/Cellar/python/3.6.4_4/Frameworks/Python.framework, but that might complicate release builds, because that assumes users have the exact version of python installed by brew.
