Hello, I checked out the latest revision of luaTeX and it works fine, both on darwin and on linux. There is only a minor flaw in the building process, namely the Makefile doesn't find makecpool in the build/ subdirectory, and rightly so, because it hasn't been copied by the build.sh script. It's really only a matter of adding, for example, these two lines to build.sh, build.sh.linux, etc. just before making the binaries: # make the binaries cp -i ../src/texk/web2c/luatexdir/makecpool texk/web2c/luatexdir chmod 755 texk/web2c/luatexdir/makecpool I have no doubt there are fancier ways to do it from the Makefiles directly but I don't know them. Apart from that, the binaries work as excepted and they don't need the pool file anymore! It's a great progress but I don't know how it works. Arthur
