Re: painter implementation for picture language in SICP

[Matt Birkholz]

I fixed the "The procedure c-call has been called with 2 arguments..." complaint. If you built Scheme from the master branch as Taylor suggested, then you should

git pull origin master

cd src/x11/

make install

to update your x11 plugin. I did this and now:

1 ]=> (paint g1 fovnder)

;The object 65536/255, passed as the first argument to integer->flonum, is not the correct type.

The nmv-header? problem should have been fixed. What version of Scheme are

you using?

I am using the x86_64 binary tarball downloaded from the GNU page as of Dec

2019, which if i remember correctly (typing this by phone) is 10.1.10.

It might be easier for you to try git master so you can test fixes as

we incorporate them.  If 10.1.10 is installed at (say)

/usr/local/mit-scheme/10.1.10/bin/mit-scheme-x86-64, do:

git clone https://git.savannah.gnu.org/git/mit-scheme.git

cd mit-scheme/src

env PATH="$PATH":/usr/local/mit-scheme/10.1.10/bin ./Setup.sh

env PATH="$PATH":/usr/local/mit-scheme/10.1.10/bin ./configure --enable-cross-compiling

env PATH="$PATH":/usr/local/mit-scheme/10.1.10/bin make -j4 cross-host

make -j4 cross-target

env FAST=y make check

(The cross-compilation business is there because we changed the ABI

between 10.1 and master; it will cease to be necessary after the next

release.  If you have a number of CPUs other than 4, you might change

the -j option to make to reflect that, of course.)

Then you can start it with ./run-build, and do:

(cd "6001")

(load "6001.sf")

(load "6001.cbf")

(load "make")
