RE: [Boost-Users] to_simple_string and Windows?

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
