because Taco changed the signature of convert from 3 parameters to 4 and I don't want to introduce that change to web2c; I leave that to Not a big deal. I will get to it the next time I have development minutes -- hopefully later today, else tomorrow morning, barring emergencies. Looking at the scripts, it might work to simply copy in the luatex convert and add " ." to the end of line 81 in texk/web2c/Makefile.in, ie, web2c = srcdir=$(srcdir) $(SHELL) $(srcdir)/web2c/convert . Of course we want to preserve the cross-compiling stuff Taco has done, which I guess for starters will mean adding native = @NATIVEWEB@ target = @TARGET@ host = @HOST@ from the luatex/.../web2c/Makefile.in and corresponding configure stuff. But just to keep going for a first native build, the above might do. - the top-level configure needs a --without-luatex switch Easy enough, of course. - the libs probably need some configure work No doubt. Whatever we have to do ... not like we have an option. k
