Compiling the Source Files Directly into a Mac or iPhone Application FAILS

What steps will reproduce the problem?

Rather than link to the GData framework, you can compile the GData library 
sources directly into your own project. To do this, drag the GData Sources 
source group from the GData Xcode project into your project's window (add by 
reference, not by copying the files.)

You can delete the references to the client services (Calendar, Contacts, 
Spreadsheet, and so on) that are not needed by your application, though they 
will not be compiled if you set the compiler flags described below in "Removing 
Unneeded Code."

If you compile the project's source files directly into your own project file, 
set this build setting:

    C Language Dialect: C99 [-std=c99] 

Search the build settings for "c99" to find the setting. If it's not present as 
a build option, and if a compile error requires c99, then set the equivalent 
user-defined setting:

    GCC_C_LANGUAGE_STANDARD=c99 

For just the Debug configuration of your target, add this compiler definition 
to ensure that the library's debug-only code is included:

    Other C Flags: -DDEBUG=1 

Or, if the Other C Flags setting is not available in your target's build 
options, set the equivalent user-defined setting:

    OTHER_CFLAGS=-DDEBUG=1 

With the source files compiled directly in your project, refer directly to the 
headers by omitting the framework name, like

#import "GDataCalendar.h"

Notes for iPhone apps compiling the source files directly:

Be sure that the files GDataXMLNode.m and GDataXMLNode.h in the 
Common/Optional/XMLSupport group are included in your project. They are 
required for iPhone builds.

iPhone applications also need these build settings in the project or target:

    Header Search Paths: /usr/include/libxml2 

    Other Linker Flags: -lxml2 

What is the expected output? What do you see instead?
A successful build should be seen but instead there are a number
of errors pertaining to the GTMHTTPUploadFetcher

What version of the product are you using? On what operating system?
Gdata version 2.0 with iOS SDK XCode 4
