Also, make sure that you have libraries and header files for
Cairo, Pango, and GTk. These libraries are not distributed with
Racket. The configure process checks automatically whether these
libraries are available.
To run `racket/draw' and `racket/gui' programs, you will need
Cairo, Pango, and GTk install. These libraries are not
distributed with Racket, and they are not needed for compilation,
except for building documentation that uses `racket/draw'.

you'll have to supply `--enable-stackup'; if the target machine is

If you re-run `configure' after running `make', then products of the

Configuration Options
---------------------
By default, Racket is compiled without support for single-precision
floating point numbers. This and other options can be modified by
setting flags in "racket/sconfig.h".
Athough `configure' flags control most options, some configrations
options can be modified by setting flags in "racket/sconfig.h".
