|It is for Pi 3B.
I am currently looking into autotools.
I got the x86 system to compile, link and actually run.
You made a good point these "system designators " are a mess.
The autotool uses three of them and naturally can identify the one where the Eclipse resides - on x86.
And they call it "build" (platform) , than the "host" is where the ARM - Raspberry is.
Exactly opposite of Eclipse terminology!
This terminology just does not jive with plain "debug" and "release" I am accustomed in C / C++.
It actually looks as both "build" and "host" are compiled / linked same time.
Using -v verbose option whenever I can!
The intergeneration of autotools into Eclipse stinks.
Too many "make" files with no way to easy see how they interact.
