Re: [racket-users] Error while compiling Racket BC
Thank you for the reply, it helped me a lot. I was following https://github.com/racket/racket/blob/master/racket/src/README.txt to build a minimal racket (both bc and cs), and now I found out a way to do that: in `racket/src` directory: ./configure --enable-cs --enable-bc --enable-csdefault make bc make install-bc this will build racket bc in `../bin`. notice here if we run `make && make install` (i.e. without the bc words), it will still build racket bc but not racket cs. then we run ./configure --enable-cs --enable-bc --enable-csdefault \ --enable-racket=../bin/racketbc make cs make install-cs this will build and install racket cs in `../bin`. So I think the document about this is not such accurate. Greetings.

The Git repo is not set up to work with `configure`, etc., out of the box. But a plain `make` in the top-level directory of the Git repo will sort out the needed bootstrapping automatically. Just use `make` at the top of the repo --- I'm pretty sure that's what you'll want to do. For more information, see "build.md" at the top of the repo: https://github.com/racket/racket/blob/master/build.md#1-building-racket-from-source As it says there, another possibility is to get a source distribution, and that will work in the `configure`, etc., way that you expect.
