Dimitry Andric <dimitry at andric dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |dimitry at andric dot com, | |dmalcolm at gcc dot gnu.org --- Comment #1 from Dimitry Andric <dimitry at andric dot com> --- It appears libgccjit.h and libgccjit++.h are installed into $(includedir), via gcc/jit/Make-lang.in: jit.install-headers: installdirs $(INSTALL_DATA) $(srcdir)/jit/libgccjit.h \ $(DESTDIR)$(includedir)/libgccjit.h $(INSTALL_DATA) $(srcdir)/jit/libgccjit++.h \ $(DESTDIR)$(includedir)/libgccjit++.h This has been the case since David committed r217374. I'm unsure why these headers seem to be installed only recently?
