Inter: fail to build 3.8, 3.9, and 3.10

[alexmyczko]

I'm trying to build the source on Debian GNU/Linux, and it fails with these messages:

[Derpitron]

I'm getting issues with this version too, except layercontents.plist is missing for Inter-Thin.ufo.I'm using Docker Toolbox, which uses Tiny Core Linux, although it should still work regardless.

[rsms]

I haven’t updated the docker image to work with some recent changes to the build system. Does it build if you setup with ./init.sh etc?

[Derpitron]

I haven't tried yet with the shell script. I'll try that.

[alexmyczko]

I would prefer to build without docker, just with fontmake -i -o otf -g src/Inter.glyphs

[rsms]

The docker image hasn’t been updated in a while. I’ll make this issue into a todo to build an updated image.

@alexmyczko Can you provide the output of git rev-parse HEAD and also the steps you took before hitting the errors above?

[alexmyczko]

git rev-parse HEAD would say nothing, since I download the tarball release as in https://github.com/rsms/inter/archive/v3.9.tar.gz

still happens with current master

[rsms]

@alexmyczko Can you please provide the steps you took before hitting the errors above? (i.e. exactly what commands you ran in what order, and if possible, also the output you see.)

[alexmyczko]

$ wget https://github.com/rsms/inter/archive/v3.10.tar.gz
$ tar xzf v3.10.tar.gz
$ cd inter-3.10
$ fontmake -i -o otf -g src/Inter.glyphs

[alexmyczko]

I haven’t updated the docker image to work with some recent changes to the build system. Does it build if you setup with ./init.sh etc?

yes that works, but i don't want to use docker, nor venv to build the font

ah and it is fontmake 2.01

[alexmyczko]

it just works providing the *.fea files at the place fontmake looks for them https://github.com/googlefonts/fontmake/issues/581

[Xylobol]

@alexmyczko Sorry for the bump, but could you send me the script you use to build the fonts? I've been having trouble getting the build script to work, so I'd like to use fontmake instead.

[rsms]

@alexmyczko Using only fontmake, you are likely getting font files with incorrect metadata, and if you build variable fonts, some glyphs will be rotated and/or slanted the wrong way.

@Xylobol fontbuild is a wrapper around fontmake.
