Wide character support is currently detected by libstdcpp3.hpp.
Is that detection not working?
I guess not. The filesystem library failed to build on cygwin with wchar-ish errors until I installed gcc4.
I've just investigated this and:
* Boost.Config is defining the correct wide-character defect macros for both gcc-3 and gcc-4 on cygwin. * Boost.Filesystem either isn't making use of them at all (the v3 code) or has outdated workarounds (v2).
I'm attaching a patch for the filesystem v2 code,
Thank you, John! Apparently I never tested the v2 code with cygwin g++-3. I'm testing now, with your patches. There are still some snafus, but I should have a fix in plenty of time for the 1.44 final release.
but the v3 code Beman will have to fix if this is to work on non-wide-character platforms.
V3 requires wide-character support.
BTW gcc 3 & 4 seem to co-exist quite happily on current cygwin, but as the default is still gcc-3 I guess we should still try and support non-wide-character platforms?
If existing Boost code supports non-wide-character platforms, I guess we should still provide that support. But any new code could require wide support IMO. Thanks! --Beman
