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 5.9.4 from offline installer

Homebrew's installation of python3 places a Python.framework in /usr/local/opt/python/Frameworks/Python.framework/, which you can use to build KLayout from. Qt can be downloaded for offline installation. You can place it in your home folder: e.g. /home/username/Qt5.9.4/. Given these two dependencies, you can successfully compile KLayout with the following commands:

# Build step
./build4mac.py -p B36 -q Qt5Custom

# Deploy step
./build4mac.py -p B36 -q Qt5Custom -y  # normal deploy
./build4mac.py -p B36 -q Qt5Custom -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 Qt594

PS: If you get a syntax error in one of ruby's libraries because it is not compatible with C++11, do not fret. You only have to change one offending file.
