Problem on build and run native client on Chrome/Moblin environment

[Zhiguo Ge]

Hi, I am trying to run test native client in Chrome under moblin system(linux).
I performed the steps in http://nativeclient.googlecode.com/svn/trunk/src/native_client/documentation/getting_started.html including

./scons --prebuilt firefox_install
python tools/httpd.py

But the following error always happens when I run the test examples such as earth, life etc:
"ERROR: The Native Client plugin was unable to load" .

I inspected the terminal that starts Chrome, and found the following information:

[840:840:4304954689:ERROR:/b/slave/chromium-linux-reliability/build/src/chrome/app/chrome_dll_main.cc(203)] Gtk: gtk_widget_get_toplevel: assertion `GTK_IS_WIDGET (widget)' failed

Can anyone give help on this?

Thanks!

hi zhiguo,

we don't have a moblin system -- we've never tried to build w/ it.

it sounds like the problem is with shared libraries used by the
prebuilt outer sandbox. could you please run the commands

ldd ~/.mozilla/plugins/sel_ldr_bin.trace
ldd ~/.mozilla/plugins/sel_ldr_bin

and send us the output? it may be just that we need to "apt-get
install" a few missing libraries. (is your moblin installation a
64-bit or 32-bit one?)

hi,

my guess is that this is the problem. though exactly what's going on,
i don't really know.

can you try running sel_ldr_bin via

/home/gezhiguo/.mozilla/plugins/sel_ldr_bin -?

and see if it'll output the flags help at all. if it won't, then it's
likely a shared library problem. if it does, maybe you could try
building some of the standalone tests, e.g., quake via make debug nacl
run in the tests/quake directory etc, and see if the basic
non-browser-side code works.

It tried /home/gezhiguo/.mozilla/plugins/sel_ldr_bin -? and it works.

 

And then I compiled and ran /tests/quake, it works too.

 

Thanks!
