I would like some help getting started with CppWamp

[nico....@gmail.com]

Hello, 

I am trying to get started with CppWamp (v0.6.2) on a Windows 7 system and I ran into some issues when building the chat example. 

I have pulled a fresh copy of rapidjson and made a project with the main from cppwamp/examples/chat. This project also has the required boost 1.59 libs (statically build for minGW-w64 gcc 5.3.0). 

I included the rapidjson headers, the boost headers (all to be sure) and headers and the source file from cppwamp/cppwamp/.

When I try to build this using minGW-w64 gcc 5.3.0 with the C++11 flag I get a compiler error that says: 

src\rapidjson\reader.h|1321|error: 'class wamp::internal::JsonVariantBuilder' has no member named 'RawNumber'

JsonVariantBuilder is implemeneted in cppwamp/cppwamp/internal/json.ipp and is an instance of VariantBuilder as defined in cppwamp/cppwamp/intrenal/variantbuilder.hpp

Both VariantBuilder and wamp::internal::JsonVariantBuilder do indeed not have a member function named RawNumber.

From the calls it seems this function should look something like:

      bool RawNumber(TargetEncoding::Ch* str, std::size_t length, bool dontParseInSitu);

Has something been changed in rapidjson that broke the example?

Is there anyone who has encountered this before and if so, is there an already known solution?

Is there anyone who knows what data the member RawNumber should contain?

Kind regards, Nico

RapidJson may have recently made a breaking change that affects all platforms. I have not updated RapidJson in quite a while, so it's possible the problem you reported affects Linux platforms as well. When I have the chance, I'll try to update my copy of RapidJson and see if I encounter the same problem.

Nico,

Try reverting RapidJSON back to revision f36af30531bc1cfa4f26d798ba1ef668812b8fd0 and see if that works. That's the revision I'm currently using.

Cheers,

Emile

I'm glad to hear you got it working on a Windows platform. :-) I'll fix CppWAMP to support the latest RapidJSON as soon as I'm able.

[Emile Cormier]

In case you haven't noticed, I made a release about a month ago that fixes the "RawNumber" problem you described.
