    ACML 5.1.0 gfortran64: missing symbols in 'fma4'-version of the lib


      Hi there!


      Some symbols seem to be missing from the gfortran64_fma4  version of the ACML, although they are present in the gfortran64 one. One example would be DTRMM:



      nm -g /opt/acml5.1.0/gfortran64/lib/libacml.so | grep dtrmm
      0000000000b4fd10 T dtrmm
      0000000000b56eb0 T dtrmm_
      0000000000b4f1c0 T dtrmmblkmata_
      0000000000b4f9b0 T dtrmmblkmatb_
      0000000000b4fdc0 T dtrmmgb2_
      0000000000b52250 T dtrmmgb3_
      0000000000b546e0 T dtrmmgb_
      0000000000b57c30 T dtrmmss_
      0000000000b574a0 T dtrmmw_
      0000000000b56b70 T dtrmmwrap_


       nm -g /opt/acml5.1.0/gfortran64_fma4/lib/libacml.so | grep dtrmm
                       U dtrmm_


      (note that "U" in the output of "nm" indicates an undefined symbol).


      This seems to make it impossible for me to use the fma4 - version with e.g. R, or am I missing something here?
