19 May 2015 This is an approved src.alt for 447.dealII in CPU2006 v1.2. This src.alt allows 447.dealII to be built against libraries that declare types in the inline namespace __1. The LLVM project's "libc++" is one such library. This src.alt is necessary for building 447.dealII with any compiler that uses libc++ as its STL. To apply the src.alt, unpack the tar file in the top level of the CPU2006 directory. The following sequence of commands should accomplish this: $ /bin/sh $ cd $ . ./shrc $ go top $ specxz -dc | spectar -xvf - Please replace the items in angle brackets ( <> ) as appropriate. To use the src.alt, please add the following stanza to your configuration file: 447.dealII: srcalt=libcxx_pair This src.alt removes the declaration of the pair in the std namespace that the benchmark source code supplies. This change is performance-neutral. Please address any questions about this src.alt to cpu2006support@spec.org.
