libv8

I have compiled V8 on Ubuntu and have a very simple V8 program called isolate_test.cc. It is based on the Hello World example from Google : #include <v8.h> using namespace v8; int main(int argc, char* argv[]) { V8::initialize(); Isolate* isolate = Isolate::GetCurrent(); //Always returns NULL return 0; } The command I use to compile this program is: g++ -Iinclude -g isolate_test.cc -o isolate_test -Wl,--start-group out/x64.debug/obj.target/{tools/gyp/libv8_{base,snapshot},third_party/icu/libicu{uc,i18n,data}}.a -Wl,--end-group -lrt -lpthread Problem is Isolate::GetCurrent() always returns NULL

I'm trying to install the following gem versions on Mavericks libv8 (3.16.14.3) therubyracer (0.12.1) Obviously therubyracer gems depends on libv8. 1) Installing libv8 What is libv8? My bit of research seems to indicaite it's some sort of javascript library used by Google Chrome? I was having trouble installing it, but this great post had both my error and a well-explained answer on how to bypass it. So I installed libv8 with gem install libv8 -- --with-system-v8 It's my understanding that this installs the gem but uses my local system installation of the v8 library instead of... the version
