klayout/macbuild

Relevant KLayout version: 0.26.5

1. Introduction

This directory macbuild contains different files required for building KLayout (http://www.klayout.de/) version 0.26.1 or later for different 64-bit Mac OSXs including:

• El Capitan (10.11)
• Sierra (10.12)
• High Sierra (10.13)
• Mojave (10.14)
• Catalina (10.15)

2. Qt5 Frameworks

By default, Qt frameworks are "Qt5" from MacPorts (https://www.macports.org/) which is usually located under:

/opt/local/libexec/qt5/

Alternatively, you can use "Qt5" from Homebrew (https://brew.sh/) which is usually located under:

/usr/local/opt/qt/

OR

"Qt5" from Anaconda3 (https://www.anaconda.com/) which is usually located under:

$HOME/opt/anaconda3/pkgs/qt-{version}

If you have installed Anaconda3 under $HOME/opt/anaconda3/, make a symbolic link:

/Applications/anaconda3/ ---> $HOME/opt/anaconda3/

3. Script language support: Ruby and Python

By default, supported script languages, i.e., Ruby and Python, are those standard ones bundled with the OS.
As for Catalina (10.15),

$ /usr/bin/ruby -v
  ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin19]

$ /usr/bin/python --version
  Python 2.7.16

Even in the latest OS as of today (December 2019), Python 3.x is not bundled with the OS, and this is the main reason why users want non-OS-standard script language support.

To meet such a requirement, the build script build4mac.py provides several possible combinations of Qt5, Ruy and Python module.
Some typical use cases are described in Section 6.

4. Prerequisites

You need to have:

• the latest Xcode and command-line tool kit compliant with each OS
• Qt5 package from MacPorts, Homebrew, or Anaconda3
• optionally Ruby and Python packages from MacPorts, Homebrew, or Anaconda3

For matching versions of Ruby and Python, please also refer to build4mac_env.py.

5. Command-line options of build4mac.py are as shown below.

6. Use-cases

In this section, the actual file- and directory names are those obtained on macOS Catalina.
On different OS, those names differ accordingly.

6A. Standard build using the OS-bundled Ruby and Python

1. Invoke build4mac.py with the default options:

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

2. Confirm successful build (it will take about one hour depending on your machine spec).
3. Run build4mac.py again with the same options used in 1. 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 in this step.

$ ./build4mac.py -y

The application bundle klayout.app is located under:
ST-qt5MP.pkg.macos-Catalina-release-RsysPsys directory, where the three parts below are important.

• "ST-" means that this is a standard package (LW-, HW-, and EX- are other possibilities explained below).
• "qt5MP" means that Qt5 from MacPorts is used.
• "RsysPsys" means that Ruby is OS-bundled; Python is OS-bundled.

4. Copy/move the generated application bundle klayout.app to your /Applications directory for installation.

If you use "-Y" option instead of "-y" in Step-3, Qt5 frameworks is NOT deployed in the application bundle.
Then the directory name will be LW-qt5MP.pkg.macos-Catalina-release-RsysPsys, where

• "LW-" means that this is a lightweight package.

If you build KLayout from the source code AND use it on the same machine, "-Y" option is highly recommended.

6B. Fully MacPorts-flavored build with MacPorts Ruby 2.6 and MacPorts Python 3.7

$ cd /where/'build.sh'/exists
$ ./build4mac.py -q qt5macports -r mp26 -p mp37

2. Confirm successful build (it will take about one hour depending on your machine spec).
3. Run build4mac.py again with the same options used in 1. PLUS "-Y" to deploy executables and libraries under klayout.app bundle.
   The buddy command-line tools (strm*) will also be deployed in this step.

$ ./build4mac.py -q qt5macports -r mp26 -p mp37 -Y

The application bundle klayout.app is located under:
LW-qt5MP.pkg.macos-Catalina-release-Rmp26Pmp37 directory, where

• "LW-" means that this is a lightweight package.
• "qt5MP" means that Qt5 from MacPorts is used.
• "Rmp26Pmp37" means that Ruby is 2.6 from MacPorts; Python is 3.7 from MacPorts.

4. Copy/move the generated application bundle klayout.app to your /Applications directory for installation.

6C. Fully Homebrew-flavored build with Homebrew Ruby 2.7 and Homebrew Python 3.7

$ cd /where/'build.sh'/exists
$ ./build4mac.py -q qt5brew -r hb27 -p hb37

2. Confirm successful build (it will take about one hour depending on your machine spec).
3. Run build4mac.py again with the same options used in 1. PLUS "-Y" to deploy executables and libraries under klayout.app bundle.
   The buddy command-line tools (strm*) will also be deployed in this step.

$ ./build4mac.py -q qt5brew -r hb27 -p hb37 -Y

The application bundle klayout.app is located under:
LW-qt5Brew.pkg.macos-Catalina-release-Rhb27Phb37 directory, where

• "LW-" means that this is a lightweight package.
• "qt5Brew" means that Qt5 from Homebrew is used.
• "Rhb27Phb37" means that Ruby is 2.7 from Homebrew; Python is 3.7 from Homebrew.

4. Copy/move the generated application bundle klayout.app to your /Applications directory for installation.

6D. Partially Homebrew-flavored build with System Ruby and Homebrew Python 3.7

$ cd /where/'build.sh'/exists
$ ./build4mac.py -q qt5brew -r sys -p hb37

2. Confirm successful build (it will take about one hour depending on your machine spec).
3. Run build4mac.py again with the same options used in 1. PLUS "-y" to deploy executables and libraries (including Qt's frameworks and Python frameworks) under klayout.app bundle.
   The buddy command-line tools (strm*) will also be deployed in this step.

$ ./build4mac.py -q qt5brew -r sys -p hb37 -y

The application bundle klayout.app is located under:
HW-qt5Brew.pkg.macos-Catalina-release-RsysPhb37 directory, where

• "HW-" means that this is a heavyweight package because both Qt5 and Python are deployed.
• "qt5Brew" means that Qt5 from Homebrew is used.
• "RsysPhb37" means that Ruby is OS-bundled; Python is 3.7 from Homebrew.

4. Copy/move the generated application bundle klayout.app to your /Applications directory for installation.

Important

So far, deployment of Homebrew Ruby is not supported.
Therefore, if you intend to use "-y" option, you need to use "-r sys" for building.

6E. Fully Anaconda3-flavored build with Anaconda3 Ruby 2.5 and Anaconda3 Python 3.7

$ cd /where/'build.sh'/exists
$ ./build4mac.py -q qt5ana3 -r ana3 -p ana3

2. Confirm successful build (it will take about one hour depending on your machine spec).
3. Run build4mac.py again with the same options used in 1. PLUS "-Y" to deploy executables and libraries under klayout.app bundle.
   The buddy command-line tools (strm*) will also be deployed in this step.

$ ./build4mac.py -q qt5ana3 -r ana3 -p ana3 -Y

The application bundle klayout.app is located under:
LW-qt5Ana3.pkg.macos-Catalina-release-Rana3Pana3 directory, where

• "LW-" means that this is a lightweight package.
• "qt5Ana3" means that Qt5 from Anaconda3 is used.
• "Rana3Pana3" means that Ruby (2.5) is from Anaconda3; Python (3.7) is from Anaconda3.

4. Copy/move the generated application bundle klayout.app to your /Applications directory for installation.
5. You may have to set PYTHONHOME environment variable like:

export PYTHONHOME=$HOME/opt/anaconda3

6F. Other combinations

Logically, several different module combinations other than 6A. through 6E. are possible, including nil choice.
If you choose such a combination, the resultant package directory name will begin with EX- (exceptional).

---

7. 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 6A through 6E).

1. Make a symbolic link (if it does not exist) 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 ST-qt5MP.pkg.macos-Catalina-release-RsysPsys -m

This command will generate the two files below:

• ST-klayout-0.26.5-macOS-Catalina-1-qt5MP-RsysPsys.dmg ---(1) the main DMG file
• ST-klayout-0.26.5-macOS-Catalina-1-qt5MP-RsysPsys.dmg.md5 ---(2) MD5-value text file

Known issues

Because we assume some specific versions of non-OS-standard Ruby and Python, updating MacPorts, Homebrew, or Anaconda3 may cause build- and link errors.
In such cases, you need to update the dictionary contents of build4mac_env.py.

Final comments

No need to say, KLayout is a great tool!
With the object-oriented script language (both Ruby and Python) support, our error-prone jobs can be simplified and speed-up.
Building KLayout from its source code is not difficult. Try it with your favorite environment!
