Hey all,

so I'm trying to use GCDAsyncSocket in a project and laid out my interface, hooked up my outlets and went to run it to make sure everything was ok (this is in Xcode 4, fyi). I get 16 Apple Mach-O Linker Errors all for GCDAsyncSocket:
Code: 
Undefined symbols for architecture x86_64:

      -[GCDAsyncSocket closeWithError:] in GCDAsyncSocket.o

I have no idea what any of those means, and am hoping someone knows how to fix the error?

Thanks,

Yeap, except I thought it was going to need to be linked to libssl. But I looked at the source code to GCDAsyncSocket and saw it included Security/Security.h. That's what actually let me know which library or framework needed to be linked in.
 
Hi all :)

Im having similar issues, (i think).
Im stuck for a few days now,

anyone knows?
 
Take the space out of the name of the folder "IOS LABS". Change it IOSLABS, or IOS_LABS, or whatever, anything without a space.

i deleted the space. the linker error still exist. just shorten:

Ignore the bulk of the text, and focus on the second to last line (the first line quoted above).

What does it imply?
 
linker error

i followed exactly: adding $(SRCROOT) then the following file. i dunno why it is still not found.
 
Does this file actually exist? Can you find it in Finder?

/Users/rc_loh/Desktop/IOS_LABS/Fyp/iphonesimulator/libPhidget21.a
 
linker error

yupps it can be found. i double and triple checked it.

is it other cause or something?
 
I'm having teh same problem as ompah - please descibe your solution a bit more

ompah said:
solved :)
had to include libxml2 for building
Click to expand...

I am getting almost EXACTLY the same error! Could you please tell me exactly how you solved it? Was it by adding
in Header Search Paths a line: /usr/include/libxml2
it didn't work for me.

Please please tell me what you have done to make this error go away [it's my third day trying to fix it]

Actually, when i added the path to the lib only in header it was not ok, i had to link it in the "Build Phrases -> Link Binary With Libraries" as well. Here I just added the libxml2 and removed any ref to the old one. Otherwise, i dont know :confused:
 
linker error help

I don't no what i need to do with this error i have not ever had it can anyone help me please.


thanks, nick

Click to expand...

Look at the first error. You have a file named (probably) DataManager.cpp which is part of your target. There should be a file containing a function TiXmlString::assign, because that's what TiXmlString:: operator= is calling. What file is it in? Is that file part of your target?
 
I have a similar problem. One of my projects has stopped working:

Undefined symbols for architecture x86_64:
"_myFunctionName", referenced from:
_callingfunctionName in my.cfilename.o

The project compiles but doesn't link. I checked carefully and the .h file is #included in the .c file with the calling function. Also the called function is correctly prototyped in its .h file and defined in the .c file. This called file is used in a lot of my projects and works in all but this one. This code doesn't call any library functions except standard C functions so I don't know what framework would be missing. I have the Cocoa, Appkit, CoreData and foundation.foundation frameworks in my project.

It appears that all of the functions that won't link call the same function. It only calls one library function: modf().

The first function that won't link calls modf(). Shouldn't this be in the basic frameworks?
