Compiled chromium source code and the execution with sandbox issue

Question

I've downloaded the chromium source and finally got it compiled. It took super long time to build the source.

I've followed the instruction in the official site

https://code.google.com/p/chromium/wiki/LinuxSUIDSandboxDevelopment

Unfortunately, the error is still there.

What I've done:

sudo cp out/Debug/chrome_sandbox /usr/local/sbin/chrome-devel-sandbox #needed if you build on NFS!
sudo chown root:root /usr/local/sbin/chrome-devel-sandbox
sudo chmod 4755 /usr/local/sbin/chrome-devel-sandbox

and I export this in my .bashrc

export CHROME_DEVEL_SANDBOX=/usr/local/sbin/chrome-devel-sandbox

and then I executed the executable and got the following error

chromium/src/out/Debug$./chrome
[22051:22051:0929/151724:FATAL:browser_main_loop.cc(160)] Running without the SUID sandbox! See https://code.google.com/p/chromium/wiki/LinuxSUIDSandboxDevelopment for more information on developing with the sandbox on.

================================================================================

By following what official site suggests,

I ran a script and got the following message:

/chromium/src/build$ sudo ./update-linux-sandbox.sh
Your setuid sandbox is up to date
Make sure you have "export CHROME_DEVEL_SANDBOX=/usr/local/sbin/chrome-devel-sandbox" somewhere in your .bashrc
This variable is currently: empty

when I typed

echo $CHROME_DEVEL_SANDBOX
/usr/local/sbin/chrome-devel-sandbox:

So I guee the export works well.

I have searched around the answer to this question but no luck so far.

Any feedback will be appreciated. Thanks

Here is what I did:

1. build on a diff machine (in my case I used a server, Ubuntu 12.04)
2. copy to my laptop (Ubuntu 13.10)
3. run it

I was able to run it but unfortunately I am still not 100% sure what the problem was. :(

I guess the build environment would be different since I share the server with others.

Hope this helps,
