nlohmann::json library error
Hi all,
I’m currently working on a project to get the current temperature with the OpenWeahterAPI, but I’m facing a problem. I work with eclipse with the internal PLCnext libraries curl and nlohmann json. I tested everything with a ‘normal’ C++ project and it works. When converting it to the PLCnext platform it doesn’t compile correctly.

#include "MyProgram.hpp"
#include "Arp/System/Commons/Logging.h"
#include "Arp/System/Core/ByteConverter.hpp"

using json = nlohmann::json;
using namespace std;
//External functions
void Cleanup(CURL* curl, curl_slist* headers);
size_t curl_callback(void* ptr, size_t size, size_t nmemb, std::string* data);
string GetRequest(const string url);
namespace My
{
void MyProgram::Execute()
{
//implement program
string _city = "jakarta";
string _key = "15fde79be05d1b10c25c13a291bdecf7";
string url = "http://api.openweathermap.org/data/2.5/weather?q=" + _city + "&appid=" + _key;
string json_string = GetRequest(url);
const char* char_str = json_string.c_str();
json j_obj;
j_obj = json::parse(char_str); //<- problem
float temperature = j_obj["main"]["temp"];
temperature -= 273.15;
}
} // end of namespace My
[/code]
The current problem is that the line ( j_obj = json::parse(char_str) ) gives a problem. The error code in eclipse is as follows:

First I thought it was a curl problem, so I added it to cmakelist. This solves my previous bug, but I still got the json problem. When trying to add json to the target link in cmake it cannot find it.

Does anybody know what is wrong?
Kind regards,

I’m currently working on a project to get the current temperature with the OpenWeahterAPI, but I’m facing a problem. I work with eclipse with the internal PLCnext libraries curl and nlohmann json. I tested everything with a ‘normal’ C++ project and it works. When converting it to the PLCnext platform it doesn’t compile correctly.

using json = nlohmann::json;
using namespace std;
//External functions
void Cleanup(CURL* curl, curl_slist* headers);
size_t curl_callback(void* ptr, size_t size, size_t nmemb, std::string* data);
string GetRequest(const string url);
namespace My
{
void MyProgram::Execute()
{
//implement program
string _city = "jakarta";
string _key = "15fde79be05d1b10c25c13a291bdecf7";
string url = "http://api.openweathermap.org/data/2.5/weather?q=" + _city + "&appid=" + _key;
string json_string = GetRequest(url);
const char* char_str = json_string.c_str();
json j_obj;
j_obj = json::parse(char_str); //<- problem
float temperature = j_obj["main"]["temp"];
temperature -= 273.15;
}
} // end of namespace My
[/code]
The current problem is that the line ( j_obj = json::parse(char_str) ) gives a problem. The error code in eclipse is as follows:

First I thought it was a curl problem, so I added it to cmakelist. This solves my previous bug, but I still got the json problem. When trying to add json to the target link in cmake it cannot find it.

Does anybody know what is wrong?
Kind regards,

CMake cannot find an nlohmann package, because nlohmann/json is a header-only library and does not have (or need) a cmake package. You do not need to make any changes to the CMakeLists.txt file to use this library.
This works for me:
- I included the header file (in my case, in the Program.hpp file):
- I used this code from the nlohmann documentation in the Execute method of my Program.cpp:
using json = nlohmann::json;
and:
(I have inserted this as an image because this Forum formats some source code in unusual ways).
The above code gives a few warnings during compilation, but ends up building OK.
Does the above code work in your program?
~ Martin.
P.S. there are a number of other issues with your code snippet, unrelated to the json library, but you may be aware of these already:
1. If this program is instantiated in a cyclic task in PLCnext Engineer, then the code will be executed cyclically, at the period defined by the Task Interval. That might or might not be what you intend.
2. The curl GetRequest call will block the Task, and (depending on the Task time settings) will probably cause a Task Watchdog error.
Please let us know in a separate question, if you need help solving these problems.
When I use your version the parse function is error free. Thanks!
Unfortunately when trying to compile is still get this error messages. All the 'In file included' are marked red:

Kind regards,

In the most recent case, it looks like there was a problem with the final step - the creation of the PLCnext Engineer library file. This looks similar to problems we have seen in the past, and can usually be solved by deleting the EngineeringLibraryBuilder directory from the %temp%\.net directory on a Windows PC.
After fixing that problem and re-building, I think you will find that a PLCnext Engineer library containing your program has been created OK.
