compilation failure with 1.54.0b1 log

[Charles Wilson <charles_j_wilson@…>]

Using Windows Visual Studio VC11 Nov 2012 CTP in generating for 64-bit, an application using boost.log from 1.54.0b1 with wide strings fails to compile where the source forge revision 854 built and worked properly.

Error message follows:

Please, try again with the version included in the Boost 1.54 beta. If it fails too, then attach the complete build log as an attachment.

[Andrey Semashev]

Oh, sorry, I misread the report. You are testing the 1.54 version, right? But anyway, attach the complete log as a file.

full compiler failure log (ZIP archive)

[Charles Wilson <charles_j_wilson@…>]

full compiler log added as requested

[Andrey Semashev]

Oddly, the complete log doesn't contain much more context of the error.

Anyway, it seems you're trying to compare an std::string with a std::wstring at some point (probably in some filter, the log doesn't contain the point of your code where that happens). Such comparison will not work, you have to compare strings with matching character types.

[Charles Wilson <charles_j_wilson@…>]

After tracing more, the issue revolves around the following macro:

BOOST_LOG_ATTRIBUTE_KEYWORD ( a_tag, "Tag", string )

the failure occurs when the type is specified as wstring.

The macro-ness led to the failure to point to a specific line in the code.

The non-wstring nature of tag is going to plague Windows developers.

[Andrey Semashev]

The type in this macro is the type of the attribute value. You can use any type there, including wide and narrow strings, as long as you use the correspondingly typed tags. But when changing that type, you have to accordingly change the filters that compare tags with strings.
