Blitz Support : |

Hi Julian, hi Markus, hello everyone!
I used blitz version 0.7 with icc (same version as you) and did not
encounter any problems. This includes the testsuite and examples (just
re-ran the whole thing and it works fine).

It happens only if BZ_NAMESPACES is defined (in config.h).
Is that the case, Markus? (It should!)
The namespace hackery is pretty much obscured by macros defined during
configuration / compiler testing. I think this is a leftover from the
old days, when not all compilers handled namespaces well (or at all)
and there were plenty of workarounds needed.
In a better world this would not happen. IMHO header files should
always fully qualify names and no preprocessor magic would be
necessary.

As mentioned above, I cannot reproduce these errors. And indeed, the
configure process of blitz is quite non-standard. You can specify a
different compiler name (CXX, e.g. with version suffix) and
compilation flags (CXXFLAGS) using the (non-standard)
--with-cxx='compiler-type executable_name compilation_flags'
configure option construct. But not the LDFLAGS: it is set explicitly
and unconditionally in configure to handle some 64 bit cases. This is
a Bad Thing since it at odds with the standard behaviour of configure
scripts. It should still be possible to override this with `make
LDFLAGS=... lib'.
I think the whole configuration machinery needs a serious overhaul to
get rid of all the obscuring and fragile cruft. I meant to work on
this for quite a while, but unfortunately I still don't have the
time. It's on the Great List Of Things To Do, though, so I'll
eventually get to do it some day.
So long
-Frank
