[H-GEN] g++ question

[Paul Gearon]

Hi all,

A friend of mine is trying to compile OpenQubit on a Sparc Solaris system.
He's using gcc 2.7 and the program is written in c++.  When he tries making
the program he gets a heap of errors, starting with:

In file included from /usr/local/lib/g++-include/std/complex.h:7,
                 from /usr/local/lib/g++-include/complex:5,
                 from qstate.h:32,
                 from qstate.cc:26:
/usr/local/lib/g++-include/std/complext.h:57: warning: friend declaration
`FLOAT real(const class complex<FLOAT> &)'
/usr/local/lib/g++-include/std/complext.h:57: warning:   will not be treated
as a template instantiation
/usr/local/lib/g++-include/std/complext.h:57: warning:   unless you compile
with -fguiding-decls
/usr/local/lib/g++-include/std/complext.h:57: warning:   or add <> after the
function name
/usr/local/lib/g++-include/std/complext.h:58: warning: friend declaration
`FLOAT imag(const class complex<FLOAT> &)'
/usr/local/lib/g++-include/std/complext.h:58: warning:   will not be treated
as a template instantiation

.... and so on for several pages, followed by a slew of parse errors.  Now
the problem is that this compiles fine with gcc 2.7 on a Linux system (intel
or sparc - we've tried both).  It looks like the compiler is choking on
templates, but I don't know why since these are in the STL.  I suggested
that he try adding the -fguiding-decls option, but he said that he got just
as many errors.

I'm stumped.  Any suggestions?
