Am new to cpp but as per project requirements i need to consume rest api and parse the response. Am able to call api & capture the response but not able to parse it using JSONCPP library.
These are the steps i followed to parse json:
- Used this command to install libjsoncpp in ubuntu sudo apt-get install libjsoncpp-dev
- Downloaded json source files and copied json header files into project folder
- Compiling cpp using this command gcc -o test.out test.cpp -ljson
it is always giving
fatal error: json/json.h: No such file or directory
#include <json/json.h>
^
compilation terminated.
Didn't find any solution since 2 days. Tried this also. Can any one tell me where i am going wrong...
Since you're on Ubuntu I went to their package website and found the file list for the package you installed: http://packages.ubuntu.com/trusty/amd64/libjsoncpp-dev/filelist
The first few files make the problem clear:
/usr/include/jsoncpp/json/autolink.h
/usr/include/jsoncpp/json/config.h
/usr/include/jsoncpp/json/features.h
/usr/include/jsoncpp/json/forwards.h
/usr/include/jsoncpp/json/json.h
Since compilers usually look in /usr/include, you need to provide the rest of the path, i.e.:
#include <jsoncpp/json/json.h>
You could also have found this file on your running system after installing the package by running this command:
locate json.h
Or using the dpkg command after installing the package.
And when you link your program, you need to say -ljsoncpp, not -ljson.
another solution:
sudo apt-get install libjsoncpp-dev
sudo ln -s /usr/include/jsoncpp/json/ /usr/include/json
