ambiguous call to overload functions in odstring.h
ambiguous call to overload functions in odstring.h
hi,
when i upgraded my vs 2003 c++ project from version 2.0.3 to version 2.2.0, i got the following compiled errors:

i am not able to fix the errors. do you know what compiler options i need to set?
please help, thank you.
my project is a vs2003 managed c++.
you have to resolve ambiguities.
this change was provided to enable usage of the /zc:wchar_t+ (treat wchar_t as built-in type) in msvc7..8
perhaps you are using string class that has no conversion operator to (const wchar_t*)
a code sample would be helpful.
vladimir
has this issue been resolved.
i have the same problem using the the latest libraries. i have done a direct replacement of the previous version files with the latest.
i am using vs 2003.
thanks
mick
it appeared that trying to enable the use of /zc:wchar_t, which is now a default in vc2005, we disabled the use of /zc:wchar_t- with /clr.
actually it looks like an ms bug, in /clr implementaiton. /clr compiler option breaks somehow the __wchar_t/wchar_t/unsigned short distinction.
that is - 2.2.0 version may be used with /clr only with /zc:wchar_t turned on.
this applies both to vc2003 and vc2005.
perhaps the issue wiil be resolved, we are working at it.
vladimir
thank you for your reply.
will you be releasing a fix for this issue and any idea of the timescale?
mick
no idea actually. we'll see what ms support will say.
vladimir
