Make OTF Error with odd "BASE" reference

Glyphs
#1

I am getting this error:

Error: “syntax error at “BASE” missing” in Feature case in line: 36

I am also getting a “Details” button rather than a “Show” button but pressing it doesn’t seem to result in anything.

The puzzling thing is that the error seems not to relate to the OT code I see.

My guess about this code is that it is referencing something on line 35 or 36 of the Case feature in the OT code. But I don’t have that many lines! I have only 30

If I delete “Case” I get

Error: “syntax error at “BASE” missing” in Feature ss10 in line: 11

This error in Feature ss10 is in spite of the compile seeming to work. Also
a) The feature was written by Auto-written by Glyphs
b) The feature ss10 has 3 lines.

In testing I have experimented with deleting all the OT code, And deleting the kerning. When I do this the error changes but I still can’t export OTFs. Only The roman in the project has this issue. The Italic is fine.

I am using Version 2.6.1 (1229) and so I thinking of going back to a previous build because file that did export to OTF previously because I am running out of ideas about how to troubleshoot this.

Please let me know what you recommend or if I can do something to help clarify what the issue might be.

Thanks as always!

Update - I am able to export file without an error showing up using 2.6.1 (1199).

Can you check the exported features.fea file in the Temp folder? It seems to create a BASE table.

Can you send the file that does not export to support at…?

Update: Do you have a glyph called BASE? In the latest makeotf, this is a reserved word.

Update 2: Or something triggers makeotf to build a BASE table, and that fails. A look into the Temp features file should explain.

Having changed the name of BASE

I now got

Error: “syntax error at “NULL” missing” in Feature ss10 in line: 38

In the “generateFont.command” document I get this:
syntax error at “NULL” missing { GCLASS CID GNAME “]” } [features.fea 355]

makeotfGlyphs [FATAL] <OmnesCyrillic-Black> aborting because of errors

So I went to the features.fea file to see what line 355 was.

And it turns out NULL had a kerning group assigned to it on that line. That’s Odd…

It must have been added using the Set kerning groups script

After I deleted that group the OTF fonts generate.

You can leave out the null glyph altogether. Any particular reason why you had it in the font in the first place?

#6

The font being extended had it in there already.

#7

I have U+25CC , glyph named it by default as BASE, should we rename it something else?

I am not using latest version of makeotf, yet. This is good to know.

#8

The default name of 25CC is dottedCircle, so this should not be a problem.
