Installation Problems

Solutions to known problems installing Envision or Scheme48: If your
problem isn't on this list, send us mail and, if you managed to
correct the problem, how you did it.
- When starting coprocessor from inside Envision,
fails claiming it can't find an 8-bit pseudo color visual.
- Your screen is probably deeper than 8-bit. Under X, a screen
can support multiple visuals and one would expect a deep screen
(e.g. 16-bit) to also offer 8-bit visuals. However,
under linux, this doesn't seem to work properly. Try running your
display in 8-bit mode.
- Scheme48 socket code doesn't work under IBM AIX, and other
errors occur.
- AIX is non-compliant. We don't know a nice way around this
and we no longer have access to an AIX machine.
Michael Sperber (sperber@informatik.uni-tuebingen.de) thinks he
might know how to make it work.
- The scheme48 socket code doesn't work under Solaris because
get-external fails.
- This apparently happens on some Solaris systems, but not others.
We don't know why. A patch from
Henry Cejtin (henry@research.nj.nec.com) is to set the environment variable
ac_cv_func_dlopen to `no' before running configure. This makes scheme48
use nlist rather than dlsym. This patch isn't ideal, as it disables
dynamic loading and means you can't strip the executable.
