In your build target, you need to exclude all the files whose names contain "YAJL".If you're using Xcode 4, this should be accessible in your target's Build Phases, under "Compile Sources".

Nathan, did you end up solving this issue? I have exactly the same problem.

What you should probably do is ./configure && sudo make install

I've read below people are getting errors when running sudo ./configure && make install

This may cause issues so try this instead: sudo ./configure && sudo make install

Hey Damien - I've been working through issue after issue with MGTwitter and then stumbled across your blog. Great post and it got me from 23 errors (which I had already got down from 163) to 5. However, after implementing the hack in your final step, it throws the final set of errors pasted below - they all seem to reference the same initWithJSON method.

1) _yajl_alloc referenced from...
2) _yajl_free_error referenced from...
3) _yajl_parse referenced from...
4) _yajl_get_error referenced from...
5) _yajl_free referenced from...

...initWithJSON:theJSON delegate:theDelegate
connectionIdentifier:theIdentifier requestType:reqType
responseType:theURL
deliveryOptions:theDeliveryOptions

located in MGTwitterYAJLParser.m

Any help would be REALLY appreciated!!

Thanks!

I had following errors
".obj_class_name_MGTwitterMessagesYAJLParser", referenced from literal-point@_OBJC@__cls_refs@MGTwitterMessagesYAJLParse in MGTwitterEngine.o

I add already the libYAJLIPhone.a static lib to Frameworks.

What's wrong??

Adding /usr/local/include/yajl to the “Header Search Paths” property didn't work for me. Compiling still gave the error 'yajl/yajl_parse.h: No such file or directory'.

My solution to the failed yajl header include was the following:

Instead of adding /usr/local/include/yajl to Xcode's "Header Search Paths" property, I just added /usr/local/include
BINGO.. problem solved.

shawn

p.s. My compile was failing with the message 'yajl/yajl_parse.h: No such file or directory' and yet /usr/local/yajl/yajl_parse.h WAS present (and readable) and the Header Search Path *did* specify /usr/local/include/yajl.

When I ran 'sudo dtrace -s /dev/stdin | grep yajl'
and then typed:

syscall::open*:entry
{
printf("%s %s", execname, copyinstr(arg0));
}

followed by Enter
followed by Control-D
followed by recompiling in Xcode... (oof!)

I saw that Xcode was trying to open /usr/local/include/yajl/yajl/yajl_parse.h.
So I just removed the extra yajl in the "Header Search Path".

BUT SURELY THIS SHOULDN'T BE NECESSARY`?!
CAN ANYONE COMMENT?

Thanks so much for this article. After going through it and, I'll admit, encountering a whole lot of errors, mostly as a result of my unfamiliarity with Obj-C, JSON, XML and the SDK, it finally works!

In my case, I had to put in "/usr/local/include/" (without the 'yajl' sub-directory) as a Header Search Path to get it to work. Wouldn't see the file otherwise. (This took a while for me to figure out :P)

A tip with adding the libxml2.dylib framework to the project:
Instead of using Finder and dragging it in, you can also command-click Resources › Add › Existing Frameworks, and chose libxml2.dylib

I could previously only find "libxml2.2.dylib", and this doesn't seem to work very well.

谢谢给这篇真好的文章！

I've followed your instructions and now when I compile, I get this...

Library not found for -lyajl

Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1

Can't find anything on the Internet to help me out. I'd really like to use this but it has been an absolute nightmare getting started with it...

Any ideas?

I've followed your suggestions above, but regardless of which search path I add it still won't compile. I still get an error about it can't find "yajl_parse.h" and 28 other dependant errors. Questions: I'm new to Mac so exactly where is /user/local/ on my drive? When I Go To Folder in the finder it says that folder doesn't exist. Do I need to add the yajl files any place physically, or just add the framework via the .a file? Do I need to add the class files in that folder to my classes? Many thanks in advance!

instead of doing:

sudo ./configure && make install

break it up into two commands:

sudo ./configure
sudo make install

I decided to do what gabriel did on yajl-objc, which is by including all of the yajl source code in the project, instead relying on that static library, because I also need this for iPhone OS 2.x.

Thanks you so so much. I've tested this and it works perfectly. I just had to change the header search path for the libxml2 to include a final '/'. Fantastic, you have no idea how long this has been doing my nut in for.

See http://files.getdropbox.com... but note that (a) this is from a stripped down copy of my app and (b) it may not be at this location long. Also you'll still need the include files (usr/local/include) etc.

Thnk2wn. Would you be as kind to upload an example of the proj? I've been struggling with this for soo long now and I'm still getting 44 errors

In the end that part didn't end up mattering in my case. I didn't see his update regarding the compiled YAJL static library for iPhone and libYAJLIPhone.a. I was able to just use that and copy the YAJL header files to the include directories and set the project search paths. I haven't tested out the code but I have it compiling now.

Dan Morgan — Mon, 03 Aug 2009 09:49:28 -0000

No :-( I also set the permissions and I still cant sudo the files into them. I'm gonna try and manually copy the files from the YAJL folder into the respective usr folders. Will let you know how I get on.

Did you get around this problem? I've tried changing the folder permissions of yajl/build/src/CMakeFiles/yajl.dir but somehow it keeps getting set back to readonly.
