Trying to get R 2.90 compiled on a CentOS 5.3 (i.e., RHEL 5.3) box, 64-bit. Machine has Opteron chips, so downloaded and installed ACML 4.3.0. Configured R with ./configure --with-lapack="-L/usr/lib64" --with-blas="-L/opt/acml4.2.0/gfortran64/lib -lacml" --with-tcltk Absolutely no problems/errors. Recommended packages there - blas and lapack both there. Ran make. Again, no problems/errors that I could find. Problems with make check, though. base -> no problems tools -> no problems Devices -> no problems graphics -> no problems stats -> failed (!) Here is what I get - suggestions/pointers to the obvious most appreciated. Error: testing 'stats' failed Execution halted make[3]: *** [test-Examples-Base] Error 1 make[3]: Leaving directory `/root/Desktop/R-2.9.0/tests/Examples' make[2]: *** [test-Examples] Error 2 make[2]: Leaving directory `/root/Desktop/R-2.9.0/tests' make[1]: *** [test-all-basics] Error 1 make[1]: Leaving directory `/root/Desktop/R-2.9.0/tests' make: *** [check] Error 2
