Okay it's all clear now, then when I build I think I have to transfer the executable and run it in the omega's terminal, it seems work when I try this

Then I will try to finish my project without OLED libraries, thank you so much!

Oh thank you this works and it's very powerful! Thank you so much!

I have just some other questions I hope you can ask...

This NetBeans setup is the same as cross-compiling for omega? Means that I can run server programs binding to Omega's IP and the omega will run a tcp server?

Another question, I tried all the combinations possible, but seems that the libonionoledexp.so can't work, I combined it with liboniondebug and libonion12c as it's suggested in documentation, and I also configured the project properties (now in compilation line the flags -l<lib> are added).. Did you use that library too?

Hey @crispyoz I'm sorry I didn't thanked you, now I'm using the Omega2+ for some projects with threads and semaphores and I wanted ask you how to add the flag -lpthread in linking (because I think it's for this that the run command gives me error in make)

@crispyoz
Okay I did all these things and I tried to build the project:

The libraries I included are:

-libonionoledexp.so
-libonioni2c.so
-liboniondebug.so

Same problem
Maybe do I need to compile another time the toolchain?

also searching "oled" no matches found

@crispyoz

Thank you I'm trying now but seems that the libonionoledexp isn't installed, this is the screen:

Okay @crispyoz thank you very much, I installed successfully Netbeans and seems to be working in the right way.
I need some other tips also because it's the first time I use a tool like this (to compile simple programs I had only textedit and the terminal).

Now I created my C project and in my source folder I have the main, for example a program to display "hello world" on the OLED screen of the omega.

How can I link the oled C libraries in the cross-compilation with NetBeans? Do I have to download them or are stored in the usr/lib folder ?

Thank you another time

Ye I found also this.

In my netbeans I see this and then I search tools and I get the last screen I posted.

@crispyoz

I'm sorry, here's my screen

@crispyoz
Thank you,
I'm trying to setup netbeans, but when I open 'tools' in the c/c++ I have a different screen:
I Need to setup a ccls configuration (?)

I tried Also a lot to crosscompile my c programs with the Onion's tutorial, but I noticed that also the c-cross-compile-example with gpioRead fails in compilation:

makefile:9: recipe for target 'gpioRead' failed
make *** [gpioRead] Error 127

Do you know if cross compilation is the only method to use the OLED expansion C libraries?
