This program does not compile because myvar is not defined.

\version "2.19.82"

test = #(cond

         ((= myvar 0) "zero")

         ((= myvar 1) "one")

          )

\markup \test

And this is the fixed version

\version "2.19.82"

myvar = 1

test = #(cond

         ((= myvar 0) "zero")

         ((= myvar 1) "one")

          )

\markup \test

The errors I get when I compile the wrong code are the following

C:/Users/GIANMA~1/AppData/Local/Temp/frescobaldi-gtv7n2o_/tmpj0pm3z6i/document.ly:2:9: error: GUILE signaled an error for the _expression_ beginning here

test = #

(cond

C:/Users/GIANMA~1/AppData/Local/Temp/frescobaldi-gtv7n2o_/tmpj0pm3z6i/document.ly:7:9: error: not a markup

\markup

\test

For me these are not enough clear to understand the problem. Is there any way to get a more precise indication of the error I did?

Yes, by reading the whole output ;-) Sorry for sounding harsh, I agree that it is non-intuitive. But often the messages for "GUILE signaled an error..." are at the very end of the log output, in this case:

Starting lilypond 2.19.82 [Untitled]...

...

Unbound variable: myvar

fatal error: failed files: "/tmp/frescobaldi-t7hq7cd0/tmpr_qtu9_l/document.ly"

Thank you, g.
