Hello,
I've managed to get guile-1.8.1 to build (with a few patches) on my
NetBSD/alpha system. Now I'm trying to investigate some failing tests.
The tests which fail are:
Running numbers.test
FAIL: numbers.test: max: big / real: (= big*5 (max big*5 -inf.0))
FAIL: numbers.test: max: real / big: (= big*5 (max -inf.0 big*5))
FAIL: numbers.test: min: big / real: (= big*5 (min big*5 +inf.0))
FAIL: numbers.test: min: real / big: (= big*5 (min +inf.0 big*5))
and then later:
Running r4rs.test
[1] Segmentation fault ${dir}${tst}
FAIL: check-guile
The others all pass which I guess is a good sign.
At this point, I have two questions.
1) Is there a more or less simple way to step through the tests in an
interactive mode where I can get to the failures in numbers.test to
really see what values are involved and causing the failure? I'm
guessing that either I'm seeing an artifact of alphas being 64-bit
systems or that alphas may deal differently with IEEE math and things
like Inf and NaN.
2) Is there a simple way to get the r4rs.test to run in the debugger so
I can either track this down myself or provide some more useful feedback?
I'm also working on getting this going on Solaris-2.9/sparc but am not
quite to the testsuite part. I have a few bug fix patches there too.
Once I get my various problems worked out, I'll submit a more cleaned up
set of patches.
Thanks
