Answer 1

Blockquote Adding libxml2 in Xcode 4.3.x

Adding libxml2 is a big, fat, finicky pain in the ass. If you're going to do it do it before you get too far in building your project.

Here's how.

Target settings

Click on your target (not your project) and select "Build Phases". Click on the reveal triangle titled "Link Binary With Libraries". Click on the "+" to add a library. Scroll to the bottom of the list and select "libxml2.dylib". That adds the libxml2 library 2 your project… but wait.

Project settings

Now you have to tell your project where to look for it three more times.

Select the "Build Settings tab". Scroll down to the "Linking" section. Under your project's columns double click on the "Other Linker Flags" row. Click the "+" and add "-lxml2" to the list.

Still more.

In the same tab, scroll down to the "Search Paths" section. Under your project's column in the "Framework Search Paths" row add "/usr/lib/libxml2.dylib".

In the "Header Search Paths" AND the "User Header Search Paths" row add "$(SDKROOT)/usr/include/libxml2". In those last two cases make sure that path is entered in Debug AND Release.

Then. Under the "Product" Menu select "Clean".

This is working and for Xcode5 too! Thank you!

Answer 2

I found the same, I had to add $(SDKROOT)/usr/include/libxml2 for the latest Xcode (4.3.x). ALSO, what kept me circling around for hours is the fact that I was modifying the "TARGET" and not the "PROJECT" (the new UI of Xcode is so intricate that its easy to overlook this). You need to modify the PROJECT!

Answer 3

On Mountain Lion I was facing same issue, which was resolved by adding /usr/include/libxml2 to include paths with flag "recursive", use this if all above is not fruitful.

Answer 4

Xcode 4.5 I have used The CW's solution entirely. The only exception is that $(SDKROOT)/usr/include/libxml2 didn't work for me, and I had to add "$(SDK_DIR)"/usr/include/libxml2 to my Projects Header Search Paths and User Header Search Paths. After that project builds successfully.

EDIT: I have Google GData project inside my project (called MyProject) (my project uses). GData requires libxml. To build project MyProject successfully, I add "$(SDK_DIR)"/usr/include/libxml2 to Header Search Paths of MyProject and no to Header Search Paths of GData . If I didnt add it to MyProject, project did not build).

Answer 5

For Xcode 6, I had to do the following:

1) add the "libxml2.dylib" library to my project's TARGET (Build Phases -> Link Binary With Libraries)

2) add "$(SDKROOT)/usr/include/libxml2" to the Header Search Paths on the TARGET (Build Settings -> Header Search Paths)

After this, the target should build successfully.

Answer 6

Follow the directions here, under "Setting up your project file."

Setting up your project file

You need to add libxml2.dylib to your project (don't put it in the Frameworks section). On the Mac, you'll find it at /usr/lib/libxml2.dylib and for the iPhone, you'll want the /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.0.sdk/usr/lib/libxml2.dylib version.

Since libxml2 is a .dylib (not a nice friendly .framework) we still have one more thing to do. Go to the Project build settings (Project->Edit Project Settings->Build) and find the "Search Paths". In "Header Search Paths" add the following path:

$(SDKROOT)/usr/include/libxml2
