Predicated execution on the NEON isn't too hard to get around. As in the code i posted you can translate:

if (cond) x = x1
else x = x0

To:

dx = x1 - x0;
x = x0;
x = x + (cond > 0) * dx;

== Adding the static library’s headers ==

We also need to make sure that our app’s build target can locate the public headers used in this static library. Open the “Build Settings” tab and locate the “User Header Search Paths” setting. Set this to “$(BUILT_PRODUCTS_DIR)” (or “$(BUILT_PRODUCTS_DIR)/static_library_name” if we want to be more specific but then we’ll have to update this setting every time we add another library) and check the “Recursive” check box. Now our built target will search our workspace’s shared build directory to locate linkable header files.

** ALSO SET THE HEADERS TO PUBLIC!!! **

If you get the error: dyld: lazy symbol binding failed: Symbol not found: _objc_retain

from: http://stackoverflow.com/questions/6308425/ios-5-best-practice-release-retain

When you migrate a project to use ARC, the -fobjc-arc compiler flag is set as the default for all Objective-C source files. You can disable ARC for a
 specific class using the -fno-objc-arc compiler flag for that class. In Xcode, in the target Build Phases tab, open the Compile Sources group to 
reveal the source file list. Double-click the file for which you want to set the flag, enter -fno-objc-arc in the pop-up panel, then click Done.

Thanks but I needed 3 steps to entierly solve the problem with my project framework:

set the Target Build Settings/"Skip Installation" property to "YES" for every dependency project

clear the Target Build Settings "Installation Directory" property for every projects

for every projects, move every headers from section "Build Phases/Build Settings/Copy Headers" Public/Private to Project

Using sox this is how you would downsample an audio file:

sox ./MM_intro_audio2.ogg -r 16000 ./MM_intro_audio3.ogg 

Also to reduce the number of channels:


sox ./MM_intro_audio.ogg -c 1 ./MM_intro_audio2.ogg

Hello All,

I just bought a Galaxy Player yesterday and wanted to root. Okay, I thought, to XDA I go. It seems the general consensus here is to use SuperOneClick.

While the SuperOneClick method may work for most people running Windows, it's fairly annoying for those in the Linux and Mac crowd. It sometimes may work after installing the correct mono application and libraries, but that's quite a bit to download.

So, I thought it'd be nice to have only one thing to download, extract, and run the root all of the Galaxy Players on all platforms.
