autogen.sh fails on MacOS 10.13.3

Hello all, I first built LO official source successfully with "build-nocheck" option in this 
January, and could start that built

app. But last week, I cherry-picked 3 commits from a forked repo which enabled vertical Mongolian 
editing, then make failed with errors occurred in unedited files. So, I thought maybe "./g pull r" 
could resolve those issues, but not.


My settings are following:



autogen.input:

--enable-dbgutil
--enable-symbols
--disable-cve-tests
#EOF


last few lines of

./autogen.sh:

which g++: /usr/local/opt/ccache/libexec/g++


gcc 7.3 was installed via homebrew and

cd /usr/local/Cellar/gcc/7.3.0_1/bin && ln -s gcc-7 gcc && ln -s g++-7 g++


g++ --version
g++ (Homebrew GCC 7.3.0_1) 7.3.0


gcc --version
gcc (Homebrew GCC 7.3.0_1) 7.3.0


I'm stuck now, I have many more commits for vertical Mongolian editing to cherry-pick to continue 
my work.

I hope anyone could give solutions to me.

Thank you.
