I have a new g++ Codelite project - on Macosx.
I am using json_to_cpp and want to compile and run a simple demo. I keep getting the following output:
/usr/bin/make -j16 -e -f Makefile
----------Building project:[ JSON_to_C++ - Debug ]----------

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [Debug/JSON_to_C++] Error 1
make: *** [All] Error 2
==== build ended with errors (1 errors, 0 warnings) ===
As I am pretty new to c++ I am trying to understand the error Undefined symbols for architecture x86_64: I have imported the headers directly into my include directory in my project folder and added the include path in my project Compiler settings.
I believe I'm almost there. When I downloaded json_to_cpp I completed the following steps to cmake:
mkdir build
cd build
cmake ..
cmake --build .
resulting in a build directory in the json_to_cpp download folder. This I presume I can think of as a library. Here is the cmake output:
auser@Users-Mac-Pro build % ls
CMakeCache.txt CMakeFiles
I can only imagine what I am doing wrong. Should I put this build folder into my path to make the contents visible to my Codelite project? Not sure how to resolve this issue, any response is appreciated.
