Hi,

via Google I have seen that the same problem was reported (and solved,
but I have no idea how to obtain the patch) in archlinux:

http://bbs.archlinux.org/viewtopic.php?pid=404588

The user who reported the problem found out that the following workaround
solves the problem on his machine:


--- blitz++-0.9.orig/blitz/compiler.h
+++ blitz++-0.9/blitz/compiler.h
@@ -114,6 +114,7 @@
#error In <blitz/config.h>: Your compiler does not support enum computations. You may have to rerun compiler/bzconfig.
#endif

+#undef BZ_MATH_FN_IN_NAMESPACE_STD
#if defined(BZ_MATH_FN_IN_NAMESPACE_STD)
#define BZ_MATHFN_SCOPE(x) std::x
#elif defined(BZ_HAVE_NAMESPACES)


but I'm hesitant to apply this without beeing able to test it myself.
The problem is: If the problem really exists it would be a FTBFS error
and thus RC critical. In this case I would like to have some more eyes
looking at the solution before breaking things at other systems.

Any opinions?

Kind regards

Andreas.

Subject: Problem with blitz++ package (debian lenny, amd64).


I upgraded yestarday my AMD64, debian, lenny.... and since, I cannot use
blitz++.
This happens with the debain package, but also when I try to compile it
from source.

The compiler complains about "labs" in the stdc++ lib. Here is the error
message:

I didn't see anything useful, but here are the files:
http://aur.archlinux.org/packages/blitz/blitz/

And the package page:
