Remove unused parameter warning in property tree json parser — at Version 3

Reported by: JL <julio.lopez@…> Owned by: Sebastian Redl
Milestone: To Be Determined Component: property_tree
Version: Boost 1.48.0 Severity: Cosmetic
Keywords: Cc:

Description (last modified by Mateusz Loskot)

Using the property json parser, in particular boost::property_tree::read_json(...), among probably other case, produces an "unused parameter 'e'" warning as follows: 

... <template instantiation omitted for brevity >....

../../src/my_source.cc:ln:   instantiated from here
/...fullpath.../include/boost/property_tree/detail/json_parser_read.hpp:115: warning: unused parameter ‘e’

This prevents the use of the -Werror flag during compilation.

Patch attached.

Attachment: json_parser_read.hpp.diff​ added

Silence the warnings from GCC about unused parameters by commenting out the second variable, leaving only the type.

Is there any chance that this patch could be applied for Boost 1.54.0?

I prefer the patch from Shane Turner, which is my opinion easier to understand.

I'm facing the same problem, I have manually patched my version. Could this be looked, it is an easy fix that has no impact and can be integrated fairly easy.

Regards, Matt
