Re: [j-devel] Maxima + ABCL status

Please let me know if anyone makes progress with Maxima and ABCL. I think my
email below is still up to date.

I found that 612 out of 4454 tests (14 percent) in the Maxima test suite
failed with ABCL. This is down from 1417 on January 22, about the time I
first tried to run Maxima using ABCL (with encouragement from Robert).
Because 423 of the tests cause the test suite to crash, I used the labor
intensive method of commenting out these tests. I can add these test files
to svn if there is interest although Robert may have a better method. The
suite runs fairly quickly on Windows XP.

If you want to compile Maxima with lisp, check out the Maxima source code
and following the instructions in INSTALL.lisp. Here are some simple
expressions that cause a crash: "exp(sin(x));", "z*%e^z;" (but it works the
second time), "diff(exp(f(x)),x,2);", "risch(x^2*erf(x),x);",
"powerseries(log(sin(x)/x),x,0);", "integrate(3^log(x),x);",
"powerseries(sqrt(1+x),x,0);". A simple expression that gives the wrong
answer: "sign(sqrt(x));" (gives "pos" not "pz").

I looked at a couple of the errors but I was unable to see what was going
on. 

In at least one case, compiled code failed but translated code succeeded. 

Maybe in the near future I will try to enumerate the errors and try to get
to the bottom of some of them.

I know this is all pretty vague. I'll try to be more precise, as time
permits.
