Building with libjson on OSX Mavericks

600 views Asked by At

I've tried the advice on threads here and here to no avail.

I have Xcode 5.0.2 installed and I am compiling everything on the command line. After make/make install to build libjson, I created a simple test file to link and build from it:

#include <iostream>
#include "libjson.h"

int main(int argc, const char * argv[])
{

    // insert code here...
    std::cout << "Hello, World!\n";
    JSONNode n(JSON_NODE);
    n.push_back(JSONNode("RootA", "Hello World"));
    JSONNode c(JSON_ARRAY);
    c.set_name("ArrayOfNumbers");
    c.push_back(JSONNode("", 16));
    c.push_back(JSONNode("", 42));
    c.push_back(JSONNode("", 128));
    n.push_back(c);
    std::string jc = n.write_formatted();
    std::cout << jc << std::endl;
    return 0;
}

When I try to build this file:

g++ -DNDEBUG main.cpp -ljson

I get this:

main.cpp:17:5: error: unknown type name 'JSONNode'
    JSONNode n(JSON_NODE);
    ^
main.cpp:18:17: error: use of undeclared identifier 'JSONNode'
    n.push_back(JSONNode("RootA", "Hello World"));
                ^
main.cpp:19:5: error: unknown type name 'JSONNode'
    JSONNode c(JSON_ARRAY);
    ^
main.cpp:21:17: error: use of undeclared identifier 'JSONNode'
    c.push_back(JSONNode("", 16));
                ^
main.cpp:22:17: error: use of undeclared identifier 'JSONNode'
    c.push_back(JSONNode("", 42));
                ^
main.cpp:23:17: error: use of undeclared identifier 'JSONNode'
    c.push_back(JSONNode("", 128));

Found the answer from another SO question after I realized the make process had problems. Basically, the solution is to copy the source code into Xcode and build it as part of the project instead of trying to link it as a library.

I also tried to build libjson 7.6.1 on an ubuntu machine (12.04) and encountered the exact problem despite a perfect make.
