Json::CharReaderBuilder builder;
std::unique_ptr<json::charreader> json_reader(builder.newCharReader());
std::string errorMessage;
return json_reader->parse(str, str + length, msg_out, &errorMessage);</json::charreader></const>

Problem using Amalgamated Source

Hi,

I cloned the jsonpp repo and followed the instructions to generate the amalgamated source here: https://github.com/open-source-parsers/jsoncpp/wiki/Amalgamated

All files generated as expected. When I then include the files in my project I get an error compiling the generated jsoncpp.cpp :

"fatal error: json/config.h: No such file or directory"

This is making sense as json/config.h was not one of the two headers generated by the amalgamated steps. But obvioulsy I am doing something wrong.

Are there additional headers or shared libraries I need to be including other than those generated by the amalgamation step?
How should I be including the generated files? I am putting the two headers (json.h, json-forwards.h) in my include directory ( eg : ./include/json/json.h) and I have jsoncpp.cpp in the top level of my src.

Thanks for your time.

How to integrate JSONCPP (DLL) into our local projects in Windows VS2015

Hi All,

I want to intergrate JSON CPP into my project.
Steps followed is :
1.Download the jsoncpp-master project this from the site.
2.Complied the lib_json project and generated the library.
3.Included the JsonCpp include folder in my local project and added the library in my project.
4.Compliation is successful, but when i run the program with some simple json data, reader.parse is returning true but the Json::Value member is showing size 1 even thought the JSON is haveing more than one node.
Is the above steps are correct??? Please let me know
I am not sure why the parsing is not happening,Any help please ?????
