Hallo,
I've just installed R on our Opteron System (AMD Opteron 246). Running make check-all
results in a failure during the lapack test:
> ## ------- tests of random real and complex matrices ------
>
> ## 100 may cause failures here.
> eigenok <- function(A, E, Eps=1000*.Machine$double.eps)
+ {
+ V <- E$vect; lam <- E$values
+ stopifnot(abs(A %*% V - V %*% diag(lam)) < Eps,
+ abs(lam[length(lam)]/lam[1]) < Eps || # this one not for singular A :
+ abs(A - V %*% diag(lam) %*% t(V)) < Eps)
+ }

+ stopifnot(Mod(A %*% V - V %*% diag(lam)) < Eps,
+ Mod(A - V %*% diag(lam) %*% Conj(t(V))) < Eps)
+ }

Error: abs(A %*% V - V %*% diag(lam)) < Eps is not TRUE
Execution halted
So this seems to be one of the combination of 64bit and gcc which leads to failures.
Using
the configure option:
--with-lapack="-lacml"
results in the same error. I am not sure wether the build uses the acml (Version 1.5)
or not.
Using pgf77 instead of g77 results in problems building R. (Missing function
definitions or
invalid compiler options (fpic))
If there is a way to overcome this problem please let me know.
Thanks in advance
