Looking to understand why the SDK is searching the host/native

(corei7-64-poky-linux) …

 

All the “crt” files are present under the target side.

 

Can someone explain what might be miss-configured ?, or better, point me
to a possible patch ?

 

I have seen some talk on-line about similar issues, but no clear
indication what the issue was, or how it was resolved…

 

I am running Yocto clang 6.0.1, cmake 3.8.2, under “rocko”, my SDK is a
standard SDK, not extensible.

Perhaps you need to use ${CC} and ${CXX} etc. in your makefile, and also
source the SDK environment script in shell, before using it.

 

Thanks,
