  2. #sdk #yocto Appears SDK searching host for files that are only present on target side

Re: #sdk #yocto Appears SDK searching host for files that are only present on target side #sdk #yocto

Khem:

Do I need to re-assign CC/CXX/CPP to point to CLANGCC, etc. in my environment-setup-coreI7-64-poky-linux script ?

I thought I read somewhere that gcc was always the default compiler under the SDK, no ?

Thanks,
Steve

its looking for tools in sdk dir, which is normal. I wonder if your apps cmake files should be using CC or CLANGCC to do linking.

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.
