[Rd] R 1.3.1 fails 'make check' on arm in the Bessel example (PR#1097)
Fri, 21 Sep 2001 06:54:39 +0200 (MET DST)
Debian tries to build its packages on a variety of platforms. The arm
platform compiled 0.90.1 (the last Debian release before the Debian package
required an Atlas library, something we no longer require) failed in 'make
check'. The log snippet follows; I traced this to the example(Bessel) code.
> matplot(nu, t(outer(xx,nu, besselI)), type = 'l', ylim = c(-50,200),
+ main = expression(paste("Bessel ",I[nu](x)," for fixed ", x,
+ ", as ",f(nu))),
+ xlab = expression(nu))
Error in title(main = main, sub = sub, xlab = xlab, ylab = ylab, ...) :
Metric information not yet available for this device
In addition: Warning messages:
1: Nonfinite axis limits [GScale(nan,nan,1, .); log=0]
2: relative range of values = 9.0072e+15 * EPS, is small (axis 1).
3: Nonfinite axis limits [GScale(-inf,inf,2, .); log=0]
4: relative range of values = 9.0072e+15 * EPS, is small (axis 2).
Casual inspection suggests that GScale(nan,nan,1, .) is probably
incorrect. Now, src/nmath/bessel* provide the Bessel functions but does this
reflect a potential libc bug in IEEE handling?
I have also asked on the debian-arm mailing list, but no result so far. I
have some access to an arm box and could compile small test cases if that
