can't map file, errno=22 for architecture x86_64

问题:

I'm having a compilation issue

回答1:

I have no idea where the item /Users/ppdeveloper/Desktop/app/RemoteDesktop/RemoteDesktop/include comes from in your compile/link options, but it looks like a directory, so it’s probably missing a preceeding -I to state that you search in this directory.

If the linker tries to load this directory as a file, it sees an EINVAL aka errno 22.
