Re: Software playing lilypond's music sheets

Hi Richard and Martin

@Richard:
the reason it failed to compile for you is because I messed up the
Makefile. It is fixed now. Lilydumper compiles just fine with g++-6
and g++-7. You can try again if you want.

@Martin:
Sadly since I use debian and didn't get much time for the packaging,
this was kind of something I was expecting to be honest. Looking at
the error message your sent, there are two issues. One is that
QT_HOST_DATA and QMAKE_SPEC are not found. The "build system" uses
qmake to determine where those libraries are installed and
automatically configure things for you. Can you check what does `qmake
-query` prints on your machine? Maybe you simply don't even need that
on fedora. You can try to edit the script in
https://github.com/s-d-m/lilyplayer/blob/master/src/configure and
comment line 56 (the one which prints
${QT_HOST_DATA}/mkspecs/${QMAKE_SPEC} and see if that works?
The other issue is that it seems some options I were using when
compiling are only available for release build, and ... I'm left
wondering how come on debian it compiled just fine for debug builds.
For that second issue you can try compiling using `make BUILD=release`
or simply update your clone from github as I just fixed that

I wanted to install Fedora on a virtualbox to see what would be the
proper fix, but sadly I got hit virtualbox not launching as described
http://linux.debian.bugs.rc.narkive.com/uLBOQlPv/processed-re-virtualbox-fails-to-start-vm-verr-ldrelf-relocation-not-supported

If some of you wants to help on the packaging side of things (someone
even asked me about windows binaries), or take over the project,
please let me know as I don't plan to spend much more time on it.

Kindest regards
