Error in Feature kern

Exported a font from FLS, exported TTF and got this:
Error: “table already specified (text was “GDEF”)” in Feature kern in line: 647

I opened the “generateFont.command” but found no clue inside this file that could point the problem:

makeotfGlyphs [FATAL] table already specified (text was “GDEF”) [features.fea 853]

Is it possible you have a GDEF in your manual feature code? Take a look into File > Font Info > Features > Prefix. And what is at line 853 in features.fea?

Hi, well this happened once again.
As I followed your advice, looking at Prefix, " table GDEF { " starts at line 130 and ends at line 132. No more lines.

Glyphs does not generate GDEF code in the prefix. Any particular reason why you put that code there? Or is it a leftover from a conversion? Have you tried removing the prefix and exporting again?

Yes his might be leftover from FLS5. Just to be extra careful - how do I remove it

OK - just disables the Prefix - export is just OK.

Cool. For future reference, here is a tutorial about porting to Glyphs:

Great - I’ll read it.
