Here are some observations about yhc's build system. (1) "scons install" doesn't seem to install anything. How do I install yhc to a standard location after building it? (2) If there is a problem with any of the scons configuration steps (e.g. libgmp or wrong version of ghc found), then "scons help" does not work at all. I thus had several days of chasing configuration issues before I could even get scons to give me its usage message! (3) There seems to be no way to tell scons to use a particular version of ghc to bootstrap with, if I happen to have several installed and want to use a specific one. (This is especially a problem if my default version is too old for yhc, like ghc-6.2.2, but for other software I don't want to change the default.) (4) There seems to be no way to tell scons to use specific build options e.g. on my powerpc G5, it would be useful to give -mcpu=g5 to all C compilations, so that it will link properly against the 64-bit libgmp that is installed. I can imagine wanting to give a bunch of options to the haskell compiler we are bootstrapping with too. Would these be difficult to fix? Regards, Malcolm
