For me, using an up-to-date MacPorts system, compilation of LilyPond
from the git works as follows.
(1) Clone `lilypond.git` or clean an existing repository with
git clean -fdx
(2) Configure LilyPond with
./autogen.sh --noconfigure
&& ./configure \
CC="ccache clang-mp-9.0" \
CXX="ccache clang++-mp-9.0" \
GUILE=/opt/local/bin/guile18 \
GUILE_FLAVOR=guile-1.8 \
--prefix="/foo/bar" \
--with-texgyre-dir="/usr/local/texlive/2020/texmf-dist/fonts/opentype/public/tex-gyre"
\
--with-flexlexer-dir="/opt/local/include" \
--disable-documentation
Remarks:
. Adjust `--prefix` to whatever is suitable for you.
. Using `ccache` is optional.
. Slightly older clang versions should work, too.
. I use TeXLive directly, so please adapt the path to the
TeX-Gyre fonts as necessary if you use the MacPorts packages
of TeXLive.
(3) Build and install with
make all && make install
(4) Run lilypond as
LTDL_LIBRARY_PATH=/opt/local/lib \
PATH=/foo/bar/bin:$PATH \
lilypond <file>
