Building the fonts from source

Requirements

To build the binary font files from source, you need to have installed the Adobe Font Development Kit for OpenType (AFDKO).

Building one font

The key to building the OTF fonts is makeotf, which is part of the AFDKO toolset. Information and usage instructions can be found by executing makeotf -h. The TTFs are generated with the otf2ttf and ttfcomponentizer tools.

Commands to build the Regular style OTF font:

$ cd Roman/Instances/Regular/
$ makeotf -r -gs -omitMacNames

Commands to generate the Regular style TTF font:

$ otf2ttf SourceSerifPro-Regular.otf
$ ttfcomponentizer SourceSerifPro-Regular.ttf

Building all non-variable fonts

For convenience, a shell script named build.sh is provided in the root directory. It builds all OTFs and TTFs, and can be executed by typing:

$ ./build.sh

Building the variable fonts

To build the variable TTFs you must install fontmake using this command:

$ pip install fontmake

A shell script named buildVFs.sh is provided in the root directory. It generates four variable fonts (two CFF2-OTFs and two TTFs), and can be executed by typing:

$ ./buildVFs.sh
