Dear Marty

Thank you. I tried to install to linux but got the
error


Could you help me?

[root@mail learn]# ls
README  learn.ms  learn_no_ar.tar.gz  lib  src
[root@mail learn]# cd src
[root@mail src]# make
cc -o learn -g '-DLLIB="../lib"' learn.c

cc -g tee.c -o tee

Do 'make lessons' if you need to extract the lesson
archives
Do 'make play; make log' to make playpen and log
directories
[root@mail src]# make lessons
rm -rf ../lib/files
mkdir ../lib/files
(cd ../lib/files; ar x ../files.a)
ar: ../files.a: No such file or directory
make: *** [files] Error 9
