There are some additional steps involved in building v8 for iOS than simply running the build_v8.sh shell script. What exactly are you trying to achieve?

[NathanWalker]

@IEFX See this section https://github.com/NativeScript/ns-v8ios-runtime#building-v8 Be sure to follow each step carefully, restating steps here for clarity:

In order to build the V8 engine for iOS and produce the static libraries used in this project follow those steps:

1. Get depot_tools

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
export PATH=`pwd`/depot_tools:"$PATH"

2. fetch v8 (this will create a v8 repo folder automatically checking out the master branch)

3. cd v8; gclient sync (this will fetch additional dependencies for building the latest revision)

Ensure you navigate back to root of project: cd ..

4. Apply patches: apply_patch.sh

5. Run build_v8.sh

The compiled fat static libraries will be placed inside the v8/dist folder.
