Re: [Denemo-devel] Compiling denemo under fedora

[Roy Rankin]

Richard,

I first saw curobj NULL when I created a test with two staffs, but notes 
in only one staff and then asked to save it in Lilypond format. I have 
also seen it happen trying to read Lilypond files.

As I have said before, my objective is that Denemo can read back in 
Lilypond files that it has written.  I have done a test of writing a 
Lilypond file from an old version of Denemo for a simple case. I have 
been able to successfully read this file in with the my version of 
Denemo from Git. However, this version cannot read back in Lilypond 
files it has written.

I have identified that the new version of Denemo writes Lilypond files 
with identifiers 3 levels deep rather than 1 level for the old version.
The reading part of the Denemo cannot cope with this new Lilypond 
structure. There may also be an issue with an extra {} around the top 
level identifier.

For comparison here are the Lilypond files for the same music generated 
by and old version and Current version of Denemo follow.

Regards,
Roy  Rankin
