I'm having some real oddities testing on Windows. Attached is a roster of the implementations for which I see test failures -- the Allegro variants and clisp. Two oddities: 1. I do not get verbose output showing what happens when the tests fail. Critical information is missing from the logfiles. I suspect that the test script assumes that standard output is redirectable in some way that it is not on Windows. See allegro-test.txt which is attached. Any idea how to get the lisp output? Any chance that REDIRECT-OUTPUTS function from script-support.lisp does not work on Allegro + Windows? 2. I get fewer failures running one test at a time than running them all in make. Allegro testing reported the following: -#--------------------------------------- Using g:/windows/allegro/32/non-smp/alisp Ran 56 tests: 52 passing and 4 failing failing test(s): test-encodings.script test-program.script test-try-refinding.script test-utilities.script -#--------------------------------------- But when I run the tests individually, only test-program and test-utilities failed. The other two tests succeeded. I have rarely seen something like this before in make on Unix variants due to not cleaning up the filesystem, but never in such a wholesale way. ---- Trying not to be a Unix bigot, but failing.... Best, R
