Unable to map file, errno = 22 for x86_64 architecture

I have a compilation problem

I have no idea where the /Users/ppdeveloper/Desktop/app/RemoteDesktop/RemoteDesktop/include comes from your compilation / link options, but it looks like a directory, so its probably missing the previous -I to indicate that You are searching in this directory.

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