The following table summarizes all the known Common Lisp implementations where STMX has been tested.
|Debian 7.0||Ubuntu 12.04LTS||Raspbian|
|x86_64||x86||x86||armhf (Raspberry Pi)|
|CMUCL||20c Unicode||x86||???||ok, need ||ok, need |
 all tested CMUCL versions need to be started with option -fpu x87, otherwise the following problems will happen on CPUs that support SSE2 or later: a) CMUCL 20c fails to load the ASDF provided by quicklisp (the builtin one is too old) with a "division by zero" error. b) all tested CMUCL versions sometimes hang in STMX test suite
