I am adding CorePlot library into an app project using Parse as database. I followed the setup steps in CorePlot documentation but came across about 50 error messages, and I found the error messages occurs when I add -ObjC to other linker flags after adding other necessary files of CorePlot.
Searching through the web, found 2 threads in Google discussion groups:
https://groups.google.com/forum/#!topic/coreplot-discuss/lmiw_kS2uOA https://groups.google.com/forum/#!topic/parse-developers/ya2gnFB80to
I do not quite understand what does it mean to use -force_load instead of using -ObjC. Does it mean I just type -force_load or -ObjC -force_load in other linker flags? I have tried both but I ended up with the same error message:
ld: file not found: -fobjc-arc
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Any help is appreciated, thanks in advance!
