[v8-users] Re: How to build V8 on Raspberry Pi (3 model B) ?

2017-06-01 Thread aleReimondo

The gn command is running executable gn at ~/v8/buildtools/linux64
IMO the binary executable was downloaded from V8 repo,
 and do not have the correct contents to be run here

pi@raspberrypi:~/v8/buildtools/linux64 $ ./gn --help
bash: ./gn: cannot execute binary file: Formato de ejecutable incorrecto

So, the gn.py is not running because it is trying to run binary code
 of wrong target.

Hi,

When I run gn (with and without arguments) I get the same error.
Is there an option to set configuration manually?

pi@raspberrypi:~/v8 $ gn args
Traceback (most recent call last):
  File "/home/pi/depot_tools/gn.py", line 38, in 
sys.exit(main(sys.argv))

2017-06-01 Thread Jakob Kummerow

It's not exactly a bug. v8gen.py, by design, replicates the configuration
of the respective buildbot, and that buildbot uses arm simulator builds.

It's really easy to change the build configuration locally though: just run gn
args out.gn/arm.release, and in the editor that opens, set target_cpu =
"arm".

Hm, that looks like a bug to me - target_arch should be "arm", not
"x86" and it shouldn't try to compile using the x86_64 version of
clang.  Consider filing a bug report.

I think you want `tools/dev/v8gen.py arm.release && ninja -C

[v8-users] How to build V8 on Raspberry Pi (3 model B) ?

2017-06-01 Thread aleReimondo

Hi,
I have made most steps detailed in V8 wiki to download prerequisites and V8 
sources.
Up to "gclient sync" all look ok, but the page at

  https://github.com/v8/v8/wiki/Building-with-GN

is not clear to me what should I run now to v8gen and then gn
 to build V8.

Trying to make and/or gyp way had not succeded here.

The shell executable is what I need to build on the Raspberry.

any help/reccomendation will be appreciated,
Ale.
