using default configure under SGI/IRIX 6.5.
(I switched to gnumake, after initial problems, this might not be necesssary).
the make rule for creating dependencies is wrong for the SGI C compiler.
The rule assumes that cc -M file.c -o file.d works (it doesn't).
One needs to explicitly capture stdout to grab the dependencies:
i.e. cc -M file.c > file.d
simple as that.
when I run tests, there are 2 errors reported
1/ in print-tests.R
(printing *very* small numbers with the statement:)
> cat("dig| formatC(signif(txn, d=dig)\n")
dig| formatC(signif(txn, d=dig)
> for(dig in 1:14)#15: Linux 2.1.120, libc-2.0.7 differs from Debian 2.0
+ cat(formatC(dig,w=2), formatC(signif(txn, d=dig), dig=dig+2,
Where the blessed version has 0 (zero), the SGI version shows 2.e-308
This looks pretty benign and is flagged in the test script as dependent on
specific libraries etc under linux.
2/ in simple-tests.R
(comparing numbers at limit of word precision)
abs(1- .Machine$double.xmax * 10^(-.Machine$double.max.exp*log10(2)))/Meps <
This statement returns F instead of T.
This may have effects in pathological cases, but doesn't seem to be a
So, it looks like a kosher build under SGI/IRIX 6.5.
*Many thanks* for a great system.
