How to compile the samples/hello-world.cc example on ubuntu 64 bit ?

[verta...@gmail.com]

Hello everyone,

I am new to v8. I am trying to achieve something that should be easy, but I just can't get it right.

I have downloaded v8 via depot-tools and built it via make x64, and now I am trying to compile the hello-world example which is given in the "samples" folder.

What command am I supposed to type in ubuntu terminal for this to work, please ?

I have tried g++ hello-world.cc -o hello -I. but that fails with the following error : 

In file included from hello-world.cc:9:0:

include/libplatform/libplatform.h:8:44: fatal error: libplatform/libplatform-export.h: No such file or directory

compilation terminated.

Thank you.

note that if you build all of v8, the hello world sample will be compiled automatically

Thank you for your answer Jochen Eisinger, but I tried this and it didn't work, of course. I couldn't switch to the 4.8 version of v8, I don't know why. Moreover, I would like to compile with an up-to-date version of v8.

can you build a current version of V8 (using gn/ninja)?

Hello,

Yes, I have built the current version with ninja. I have also seen that the hello-world.cc sample has been compiled when I built V8. However, I still don't know what I have to do in order to compile it myself in terminal.

"g++ I. hello-world.cc -o hello" doesn't work at all.

Nor does "g++ -I. hello_world.cpp -o hello_world -Wl,--start-group out/x64.release/obj.target/{tools/gyp/libv8_{base,libbase,external_snapshot,libplatform},third_party/icu/libicu{uc,i18n,data}}.a -Wl,--end-group -lrt -ldl -pthread -std=c++0x"

I have tried to adapt with something like

"g++ -I. hello-world.cc -o hello_world -Wl,--start-group out.gn/x64.release/obj/{libv8_{libbase,libplatform},third_party/icu/libicu{uc,i18n}}.a -Wl,--end-group -lrt -ldl -pthread"

But that doesn't work either, I get

In file included from hello-world.cc:8:0:

include/libplatform/libplatform.h:8:44: fatal error: libplatform/libplatform-export.h: No such file or directory

compilation terminated.

I really want to compile this because I have written a simple V8 program derived from Hello-World.cc and I would like it to be working.
