racket-cs build failure JFYI (fixed)

[John Clements]

Hmm… building racket cs is failing for me like this right now:

This is immediately after a git pull and a git clean -xdf. I was compiling with RACKET=racket, using a built-in installation of racket v7.7.0.1.

I rebuilt the racket I was using as the helper, and this error went away. I was suprised; it didn’t look like the kind of error that would be caused by an out-of-date helper. Ah well.

Yes, this is as intended: RACKET=racket requires the same version for
both the helper and the Racket being built.

Okay, that makes sense. Can I suggest a friendly amendment to the following section of build.md? (the only change is in the first line):

Current:

If you have a sufficiently recent Racket installation already with at
least the `"compiler-lib"` package installed, you can supply
`RACKET=...` with `make cs` to skip that part of the bootstrap. And if
you have a Chez Scheme source directory already, you can supply that
with `SCHEME_SRC=<dir>` instead of downloading a new copy:

Proposed:

If you have already compiled the current version of Racket with at
least the `"compiler-lib"` package installed, you can supply
`RACKET=...` with `make cs` to skip that part of the bootstrap. And if
you have a Chez Scheme source directory already, you can supply that
with `SCHEME_SRC=<dir>` instead of downloading a new copy:

The list of identifiers exported by the kernel are compiled into the
expander -- the expander doesn't maintain its own list. So this is an
expected sort of error with an old bootstrap copy of Racket.
