Actually.... I'd wager that no one has directly answered your question
because you haven't told us what you are trying to do. The answers
you receiver were correct and equally as vague as your question.
I have a Cocoa application that I am compiling in the traditional UNIX
manner using Makefiles and I want to be able to invoke it with
command-line arguments and without creating/installing it like
traditional OSX apps, as in "x.app/Contents/MacOS/x".
If your makefile is constructing a .app wrapper with the binary and
Info.plist located in the correct spots and containing the correct
contents, then it should just work.
There is absolutely nothing proprietary or secret about how Xcode
builds projects other than the projects and build system are optimized
to building Cooca applications; you can do the same thing from
makefiles, shell scripts, or manually, if re-inventing that wheel is
required (and it sometimes is!).
When I tried the
usual thing that works on UNIX, compiling to binary and just running
it, my application got mouse events but no keyboard events, among
other strange things.
That indicates that you didn't build your app wrapper correctly.
Either you didn't correctly set up the Info.plist or your application,
itself, isn't starting up the GUI bits correctly.
Or maybe you are trying to eliminate the .app part. Definitely
neither supported nor encouraged, but it can be done.
In any case, you didn't provide enough information for anyone to
answer a question with architectural specifics.
Is there a way to do this without making some kind of wrapper caller
that generates the directory and a script or some such? Or is it
wholly frowned upon to do what I'm wanting, and if so, why does it
half-work rather than fail with a decent error message?
There is -- see Eric's followup for a clue -- but is wholly frowned
upon and will lead to a non-standard user experience.
Without knowing what you have done, it is hard to tell why it half-
works.
You can either post more details about what you have done and continue
down this path.
Or you could give a bit of information about what you are trying to do
and see if someone might suggest a path that is a bit more standard
and, subsequently, considerably easier.
In Cocoa, if something seems absurdly hard to do, it is most likely
because the something is wrong.
