Re: [Boost-Users] to_simple_string and Windows?

11 Jun 2003


      Yes, I know about the UNICODE project option, that is why I mentioned it in
my previous email...
Anyway, now I am left wondering why opto enabled (with /O3 or whatever opto
is required) causes my call to "to_simple_string" to fail.  In case anyone
is wondering what I mean by that, it simply aborts without any further
information somewhere in the bowels of said function.

UNICODE is enabled by the _UNICODE define.  Assuming you're still using
MSVC
6 (remember to rebuild all often since your dependencies may not getting
generated correctly), just go to your Project/Settings/C/C++ tab and in
Preprocessor definitions, remove the UNICODE symbol from the list.
Otherwise, remove it from your Makefile.

It is not a compile-time error, but rather a run-time error.
Ie. if I compile any program which utilises
boost::to_simple_string with any
optimisation whatsoever; it simply aborts at the point where I do my
function call to "to_simple_string".  That is irrespective of
my using a
type date or ptime as the function argument...
I must stress again that "to_simple_string" works fine when I
compile it in
Linux.
O, another question I have.  Where do I disable Unicode
support (wchar_t
usage in fact!) alltogether for Boost?
Previously I had great fun with lexical_cast.hpp which
utilised wchar_t
versions of some of the streaming operators because I had a
silly UNICODE
define as part of my project options.  The solution was to
use /Zc:wchar_t
project option in M$VC6.
But UNICODE defined caused problems in network browsing code
I used which
`normally' returned a LPSTR instead of the LPWSTR if UNICODE
is defined.
Long story.  I did a temp hack in lexical_cast.hpp by
# define DISABLE_WIDE_CHAR_SUPPORT
#undef BOOST_NO_INTRINSIC_WCHAR_T
and getting rid of the redefinition of BOOST_NO_INTRINSIC_WCHAR_T.
Now is there a way to do this cleanly, compile-time so that I
do not need to
keep on hacking the source code?
Greetings,
Andre.

Darn; here I go replying to my own post again...
Anyway; so far I have narrowed the problem down to one of
optimisation.
I
did a debug compilation and had no problem.  A moment of
reflection led
me
to the conclusion that optimisation might have something
to do with it.
For
the record; I am using Boost in Windows, with Visual
Studio as IDE only,
and
the Intel 7.0 compiler.  Oh; and STLport instead of
Windows' crappy STL
implementation.
I.e. turning on "Maximise speed" optimisation causes
"to_simple_string"
to
fail on my build system.
I'll try to setup the simplest proggie I can to
illustrate this problem.
Any thoughts?
I'm not aware of anyone else having a problem.  Perhaps you can post
the details of the compilation failure?
Jeff
