Re: [MIT-Scheme-devel] scheme/edwin build problem?

[Chris Hanson]

Huston,

Do the following to get this working (only the rm and
etc/build-bands.sh are different from the standard instructions).
Unfortunately I didn't notice because I only tested the 64-bit
versions carefully, and this particular problem doesn't seem to occur
with them.

Sorry for the trouble.

tar xzf mit-scheme-9.1-i386.tar.gz
cd mit-scheme-9.1/src
./configure
make compile-microcode
rm lib/*.com
etc/build-bands.sh
sudo make install
