(1) "scons install" doesn't seem to install anything. How do I install yhc to a standard location after building it?
It should print a message about being installed on an unsupported system. Not having a Mac machine to test on, or having any clue about where things should live means I can't write the installer portion of the build system.
Yes, it does say something like Sorry, don't know how to install on your platform. five or six lines before the end of the output (but I didn't see it at first). Installation on a Mac should be pretty much the same as on Linux, or any other unix-like platform. e.g. /usr/local/bin and /usr/local/include, or elsewhere if there was a --prefix= option. By the way, there is no "scons install" target listed in the help message.
(2) If there is a problem with any of the scons configuration steps
then "scons help" does not work at all.
I've fixed this now.
Excellent! Yes, this bit works now.
(3) There seems to be no way to tell scons to use a particular version
of ghc to bootstrap with,
You can now run scons and add a ghc=<path to ghc> options.
Great. Looks good.
(4) There seems to be no way to tell scons to use specific build options
This has always been supported, but only just documented :-) Yhc picks up the CCFLAGS environment variable. Simply build as: CCFLAGS="-mcpu=g5" scons
Right. Unfortunately, scons does not seem to respect the CCFLAGS variable when it is doing its own configuration tests. So on my machine, scons cannot recognise the installed libgmp, because the test for it requires certain C flags (-m64) to succeed, but these are not passed through. Regards, Malcolm
