[Blitz-support] Compiler error for array/asexpr.h with Intel compiler under Linux

[Pacey, M. <m....@la...>]

Caveat: As I'm not a C++ programmer, I'm not able to diagnose exactly what's causing the error, but as the messages point to blitz/array/asexpr.h this mailing list seems the best place to start looking for advice.

I've been asked by one of my users for help installing a piece a software calling itself SDW which has several dependencies including boost and blitz. I'm attempting to get this compiled using the Intel compiler suite - mostly because it will integrate nicely with the built-in Math Kernel Library. All the dependent libraries including boost and blitz seem to build fine under Intel (I'm using 12.1). When I attempt to build the main app, though, I get an error message from within a blitz header:

I checked the offending lines in both the install directory and the original build dir - it looks like the offending line comes directly from the blitz tarfile, and isn't modified in any way during the blitz build process. My C++ isn't good enough to work out what exactly is wrong here - compiler bug, bad build of one of the dependent libraries? My hope was that it was simply using a different C++ standard, so I cycled through all icpc's possible "-std" flag options with no joy. I also switched to Intel compiler version 13, but the errors are the same.

Any suggestions on how to proceed appreciated.

Regards,
Mike.
