Hi all,

RuntimeError: Compilation error:
/tmp/tmpl7pw9bvn/lib.o: file not recognized: File format not recognized
collect2: error: ld returned 1 exit status

I try fix directory of “net.tar” file but the directory for extracting lib.o (/tmp/tmpl7pw9bvn/lib.o) isn’t exist.
How can i fix it?
Many thank!

Looks like you did not set the target_host for cross compilation correctly.


You can query it by executing “gcc -v” on your board and looking for the line starts with Target:
