Hi,

I have successfully cross compiled the node binary for version0.8. and
running the same in the hardware.
Now i wrote *.cc and wscript file which helps in interfacing the C++ with
the Java.
When i compile and build the same as "node-waf configure build" the
compilation steps are successful, and i get a *.node file inside
./build/Release folder.
I copied the same from the ubuntu to the Target, but i get the below error.

*root@bosch-nemid:~/Release-2# node ARM.js*
*[ 2971.577489] Alignment trap: not handling instruction e1923f9f at

Please find below the code of wscript:

Note:

I have a folder in my Ubuntu which replicated my Target Root file system,
And i have made sure i point to that as the Library Directory path.
Also i am not using the Default Gcc compiler instead i am using the
MontaVista C++ compiler.
I set system env like CC,CPP,AR,RANLIB Variables to point to the rite
Montavista binary path.

can some one help.
thanks in advance.

First thing you should do is switch to gyp.

Hi,

I shifted to gyp, and wrote binding.gyp, but still when i copy over the
*.node file to Hardware which is successfully created in my ubuntu cause me
the following error,

Some times for the same i get the below error, when created the *.node
using gyp in the Ubuntu platform and copied in to the Target.

init must be non-static or it won't be visible to dlsym(). But
preferably use the NODE_MODULE macro.

Hi Ben,

I removed the static from all the places from the above code, and i still
get the same error.
Also do you mean NODE_SET_METHOD, since i am using NODE_MODULE to call init
function.

Sorry, for some reason my mail reader didn't show the last two lines
of your email. What does `nm yourmodule.node | grep -E 'init|_module'`
print?

Hi Skyler,

For some reason i am not able to view your mess , it just shows "4 --".
Can you please reply back.

Hi Pavi,

That's a mail-reader fail.  That was meant for another thread.  Kindly disregard!  :-)
