build failure with gcc-4.6.0 on solaris

[Burcin Erocal]

Hi,

on sage-devel [1], David Kirkby reports about the problems he
encountered while compiling Sage with gcc-4.6.0 on solaris.

[1] http://groups.google.com/group/sage-devel/t/c8465f62d0c3832d

One of the issues is with Singular:

http://trac.sagemath.org/sage_trac/ticket/11084

Here is the error message from the ticket description (probably
mangled by my mail client's line wrapping):

Any ideas?

Hi Burcin,
meanwhile I got access to an Opensolaris machine with gcc 4.6.0.

> Any ideas?
The C++ function name demangling of the function shows something funny:
> nm factory/facFqBivar.o > out ; c++filt out|grep uniFactorizer
> [15] | 272| 5397|FUNC |LOCL |0 |1 |uniFactorizer(const CanonicalForm&, const Variable&, const bool&).constprop.36

There is an additional suffix .constprop.36 after the declaration.
From
http://google-glog.googlecode.com/svn-history/r91/trunk/src/demangle_unittest.cc
I understand, that the suffix is something new from gcc 4.5/4.6, maybe
the sun linker doesn't like it?

My best,
Alexander

I got the same error with the Fedora 15 alpha (which uses gcc 4.6), so its not a Solaris issue.
