We can also add a exists(/usr/bin/ctfconvert) to catch the case were the user caused it to not be there. > Why not just always add ctfconvert to bootstrap tools when it is needed? > I don't know how long it takes to build though, but it is probably > nothing compared to LLVM ;-). It's probably not too bad to add, but I don't think it's changing all that quickly so as long as people remember to update Makefile.inc1 it shouldn't too bad. -- Brooks
