Hi all,
I've only now noticed that on our Opteron boxes running Suse Enterprise Server 8 that R-2.0.1 did not pass make chek-all. It bombed in tests/lapack.R at:
eigenok <- function(A, E, Eps = 1000 * .Machine$double.eps) {
V <- E$vect
lam <- E$values
stopifnot(abs(A %*% V - V %*% diag(lam)) < Eps, .... [TRUNCATED]
Ceigenok <- function(A, E, Eps = 1000 * .Machine$double.eps) {
V <- E$vect
lam <- E$values
stopifnot(Mod(A %*% V - V %*% diag(lam)) < Eps, .... [TRUNCATED]
sm <- cbind(1, 3:1, 1:3)
eigenok(sm, eigen(sm))
Error: abs(A %*% V - V %*% diag(lam)) < Eps is not TRUE
This is using: ~/R-2.0.1> gcc -v Reading specs from /opt/gcc33/lib64/gcc-lib/x86_64-suse-linux/3.3/specs Configured with: ../configure --enable-threads=posix --prefix=/opt/gcc33 --with-local-prefix=/usr/local --infodir=/opt/gcc33/share/info --mandir=/opt/gcc33/share/man --libdir=/opt/gcc33/lib64 --enable-languages=c,c++,f77,objc,java,ada --disable-checking --enable-libgcj --with-gxx-include-dir=/opt/gcc33/include/g++ --with-slibdir=/lib64 --with-system-zlib --enable-shared --enable-__cxa_atexit x86_64-suse-linux Thread model: posix gcc version 3.3 20030312 (prerelease) (SuSE Linux)

R is now configured for x86_64-unknown-linux-gnu

Actually, I've only noticed this when the samething happens on a RH-based box (same hardware), using: $ gcc -v Reading specs from /usr/lib/gcc-lib/x86_64-redhat-linux/3.2.3/specs Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --enable-languages=c,c++,objc,java,f77 --host=x86_64-redhat-linux Thread model: posix gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-24)
I'd very much appreciate any pointers!
Best, Andy
