Open ios/YourAppName.xcodeproj in Xcode Right-click on Your App Name in the Project Navigator on the left, and click New File… Create a single empty Swift file to the project (make sure that Your App Name target is selected when adding) when Xcode asks, press Create Bridging Header and do not remove Swift file then. re-run … Read more

There doesn’t seem to be any mention of any equivalent pragmas in the GCC manual’s page on pragmas. One reason I saw for GCC not supporting linking in source code was that sometimes, correct linking depends on link order; and this would require you to make sure that the linking order happens correctly no matter … Read more
Static libraries increase the size of the code in your binary. They’re always loaded and whatever version of the code you compiled with is the version of the code that will run. Dynamic libraries are stored and versioned separately. It’s possible for a version of the dynamic library to be loaded that wasn’t the original … Read more
Dynamic linking can reduce total resource consumption (if more than one process shares the same library (including the version in “the same”, of course)). I believe this is the argument that drives its presence in most environments. Here “resources” include disk space, RAM, and cache space. Of course, if your dynamic linker is insufficiently flexible … Read more
There are (in most cases, discounting interpreted code) two stages in getting from source code (what you write) to executable code (what you run). The first is compilation which turns source code into object modules. The second, linking, is what combines object modules together to form an executable. The distinction is made for, among other … Read more
I have no idea what Yesod is, but I know exactly what each of your other errors means. First, you should not try to link statically. The warning you get is exactly right: if you link statically, and use one of the routines for which you are getting the warning, then you must arrange to … Read more
