Problem using Amalgamated Source

Noah Keen — Thu, 07 Jun 2018 15:27:55 -0000

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

Anupkumar — Mon, 28 May 2018 07:39:20 -0000

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 ?????

#19 toStyledString produces different output than operator<<

#19 toStyledString produces different output than operator<<

Christopher Dunn — Fri, 06 Mar 2015 19:01:40 -0000

I think it's the same now at: https://github.com/open-source-parsers/jsoncpp/

But we make no guarantees for toStyledString(). To control the format, use StreamWriterBuilder.

 I had expected just about everything should be able to retrieve as String -- including objects and arrays \(feature suggestion\).

#20 asString() of intValue throws exception

Objects and arrays are serializable to strings, but not strictly convertible. Maybe it's an unfair distinction, but since serialization has so many special cases, we're stuck with this for now.
