[Boost-users] PGI compile problem with lanczos_sse2.hpp

Subject: [Boost-users] PGI compile problem with lanczos_sse2.hpp
From: Brian Carnes (bcarnes_at_[hidden])

I am trying to link to a library that uses some code from boost.  So far I have been able to build the code under gcc, intel and pathscale compilers.  However, I get about 100 errors from this file under pgi (versions 7.1, 7.2 and 10.1)

   boost/boost/math/special_functions/detail/lanczos_sse2.hpp

I have copied the first few error messages to the end of this email.  My suspicion is that some settings are not correct for this compilation under PGI.  I did check that the header files used by "lanczos_sse2.hpp" were present.  I don't have any experience with the SSE/SSE2 optimizations.

FYI, our build system uses bjam, so there is a Jamfile for boost, which I can send if needed.

Thanks for any assistance,
-Brian
