node-waf cross compilation, creating a *.node file which is created under ubuntu and run in ARM processoe

[Pavi]

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

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.

I finaaly managed to  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.

[Pavi]

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?

[Pavi]

 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.  

[Pavi]

Hi Skyler,

For some reason i am not able to view your mess , it just shows "4 --".

Can you please reply back.

[Skyler Brungardt]

Hi Pavi,

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