Errors when adding C libraries to a project with ARC

Question

I am trying to use a set of C libraries to allow custom graphs in my iOS project. My projects uses ARC, however, the custom graph libraries are based on a project that does not use ARC. The errors I am getting are related to ARC.

The documentation for the C libraries specify that when using the library to turn off ARC. However, my project is too evolved to revert to a non ARC project.

How might I still use this library in my project? The library is PowerPlot.

If the library documentation tells you to turn off ARC, your option is to turn off ARC or not use the library. — nhgrif, Sep 27 '13 at 22:21
@nhgrif *turn off ARC*, and *turn off ARC for the specific library* are fairly different concepts. Especially when the OP is saying *my project is too evolved to revert to a non ARC project* — Gabriele Petronella, Sep 28 '13 at 04:40

You can turn off ARC for the specific library, by adding the -fno-objc-arc compiler flag.

Go in your Target Settings > Build Phases > Compile Sources, and add the compiler flag to every implementation file from the library.

Further information can be found here: How can I disable ARC for a single file in a project?

Minor typo. Should be `-f` – rmaddy Sep 27 '13 at 22:35
I fixed it while you were typing probably. It should be ok now ;) – Gabriele Petronella Sep 27 '13 at 22:51
