I am trying to develop an application in xcode using objective c with SUP backend.When I builded my project I got an error like

Can anyone please help me in solving this?
Duplicate symbol means you have the same symbol (class, variable, etc) defined in two places in your project (or its included libraries).
Look at the error messages...it looks like you've included the same file in your project twice:
dev_BhaskarG_com_igate_shipping_v1KeyGenerator
dev_BhaskarG_com_igate_shipping_v1KeyGenerator copy

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.
i am new to Xcode and obective-c and I have a problem with a project I have taken over from another developer on another machine. I cannot contact this programmer anymore (fired).

Can anyone help me with this?
You are missing the library file libABCityCrossMarketing.a.
A google for "ABCityCrossMarketing" returns nothing for me. Looks bad. If you still have access to his machine, then that looks like the only way to recover this file (it's possible this library was written by him and never published).
The message is clear here, I think:
library not found for -lABCityCrossMarketing
This happens when you move folders and the controls or basically any file is misplaced by Xcode and it doesn't know where to find it. You'd have to add it to your project again or change the path to it wherever it was listed.
Last night, when I finished working on my project, there were no errors. But today, when I opened my project, I had the Apple Mach-O link (id) error.

ld: 4 duplicate symbols for architecture i386

`
Can anyone help me out?
Several symbols, (WhereAmIAppDelegate._window, WhereAmIAppDelegate._viewController, ...) are defined duplicate: in WhereAmIAppDelegate.o and in WhereAmIViewController.o.
A likely cause for this error is that you have imported an ".m" file instead of the ".h" file somewhere. Perhaps you have an #import "WhereAmIAppDelegate.m" in WhereAmIViewController.m" ?
after adding the OCMock framework i got that strange error... :(
ld: file not found: -fobjc-arc
clang: error: linker command failed with exit code 1 (use -v to see invocation)
It looks like if the compiler flag tries to be loaded by XCode?
Any idea?
Best regards, hijolan
I was getting the exact same error on Xcode 4.3.2. Here's my navigator log; I'm adding it for Google juice.

The OCMock instructions explicitly ask you to add linker flags -- -ObjC and -force_load.
-force_load is expecting a value -- see the answer to this question that explains that -all_load is what to use if you don't want to specify a library name.
As someone who just spent 25 minutes on this, I should check again with the OCMock tutorial -- I don't think it was very clear in this instruction.
This blog post has a much better image that shows exactly how your settings should look.
I'm compiling a project in Objective-C depending on libraries in C.
The compilation fails with the following error:

The problem I see is that this library isn't even specified in the link command! Why is this needed at all?
Yours,
Emmanuel
Someone had enabled OpenMP using "other flags" which causes the -lgomp library to be included. :-(
