On macos 10.14.6 using clang++ with macports dependencies
and disabling qt and GUI I see the following error when running "make check" :

------------------------------------------------
/Applications/Xcode.app/Contents/Developer/usr/bin/make  check-local

------------------------------------------------

prefix is set to "/opt/octave/6.0.90" so I see why mex is looking for those files,
but I have not yet run "make install" so it is correct that they do not exist.

Two libraries (-loctinterp and -loctave) are linked in on Mac (and Windows) by "mkoctfile".
Before installing Octave, these two libraries are in $(top_builddir)/libinterp/.libs and $(top_builddir)/liboctave/.libs, respectively.

Would it be possible to link to the libraries at these locations?

If yes, one way to fix this could be to change the code for "mkoctfile":
https://hg.savannah.gnu.org/hgweb/octave/file/5d4b400e4b66/src/mkoctfile.in.cc#l231

Is there a way "mkoctfile" can know whether it executes from the build tree or after installation?

Alternatively (and probably easier and less messy), we could probably add the necessary -L flags in the make rule:
https://hg.savannah.gnu.org/hgweb/octave/file/5d4b400e4b66/test/mex/module.mk

If this approach works, I like it as being a minimal change.

--Rik

I don't know if that would mess things up for other platform or if we can pass the -L flags in the make rule unconditionally on all platforms.

@Carlo: Do the tests with .mex files pass if you set LDFLAGS accordingly?
I'm not sure how things work on MacOS. But maybe you could run something like this in the build directory:
make LDFLAGS="-L$(pwd)/libinterp/.libs -L$(pwd)/liboctave/.libs" check
