str2f une now issues
a warning for invalid
input.
MEX-files and
utilities that rely on
the (jrCC compiler
might need to be
recompiled due to an
upgrade to GCC. 3.4.
In previous versions,
str2f une accepted a
path to a file instead of
a function name. Now it
issues a warning, and
will produce an error in
future versions.
At the source-code level,
GCC 3.4 now complies
much more strictly with
the C++ standard and
rejects certain
constructs that were
previously accepted, but
which are contrary to
the language standeird.
Change the pathname
input to str2f une to a
function name to avoid the
warning.
This means that aU objects
linked into MATLAB
(either statically or
dynsunically) must be
recompiled with GCC 3.4.
