Hi Owen,

FWIW, I did:

git checkout remotes/origin/dev/lamb/GSoC-2020
rm -fr build/
sh autogen.sh --noconfigure
mkdir -p build/
cd build/
../configure
make -j3 CPU_COUNT=3

failed with:

/home/hermann/lilypond-git/flower/jsoncpp.cc: In function 'void
Json::throwRuntimeError(const String&)':
/home/hermann/lilypond-git/flower/jsoncpp.cc:2620:25: error: exception
handling disabled, use -fexceptions to enable
   throw RuntimeError(msg);
                         ^

A subsequent `make'  from current master i.e.
751d453f9172c7dff81d11181158051065badeaf
succeeded.

Not sure whether this helps...


Cheers,

P.S.
Let me take the opportunity to thank you for your work.
Although it's a topic where I can't help, I enjoy reading your posts.
I think we should make weekly reports a requirement for all GSoC
projects in future. In the past there were projects where I may have
been able to help, but I didn't get any (at least too little) infos on
the mailing-list.
