I pushed a fix for this here https://hg.savannah.gnu.org/hgweb/octave/rev/ff6c90eb6f2d.

Try any cset after ff6c90eb6f2d.

Yeah, to be complete, the options that are missing are

-L$OCTAVE_HOME/lib/octave/$OCTAVE_VERSION -loctinterp -loctave

Building the program with

mkoctfile --link-stand-alone foo.cc -L$OCTAVE_HOME/lib/octave/$OCTAVE_VERSION -loctinterp -loctave


These are the pieces that we intentionally removed when building oct files, but they need to be kept in place for linking standalone programs with mkoctfile.

Your patch looks like a good start.

Confirmed.  Attached is a diff that could take care of this one issue.  However, it isn't the full solution because the example of standalone.cc still does not compile.  The link command also needs -LOCTLIBDIR.  Maybe this mean more thinking is needed.

When building oct files, we don't link with -loctinterp and -loctave by default now, which is good. But we lost the link with these libraries for standalone programs at the same time, this needs to be restored.
