Failed to launch hello_world.cc

[劉君羿]

I am using ubuntu 10.04 on x86_64 machine.

I built v8 with "make native",

and copied and pasted the hello_world.cc to the root directory of v8.

I typed "g++ -Iinclude hello_world.cc hello_world", and it gave me the following error:

/tmp/ccjmXg7T.o: In function `main':

Please follow the provided instructions:

Compile hello_world.cpp, linking to the static libraries created in the build process. For example, on 64bit Linux using the GNU compiler:
g++ -Iinclude hello_world.cc -o hello_world out/x64.release/obj.target/tools/gyp/libv8_{base,snapshot}.a -lpthread

Simply omitting the reference to the libraries is not going to work. Since you built with "make native", you'll have to adapt the path to "out/native/...".
