Failure build sdk with clang tools included

[reid-p]

I'm getting the following linker error while trying to build an arm sdk with the clang tools included. Any ideas?

[kraj]

I think we need to add -lgcc or -lunwind when building libcxx

[kraj]

recipes are upgraded to use 9.x RC, please try with the latest master and report back. Also, post your build configuration so we can reproduce your case.

[reid-p]

Just did a quick try and failing in the configure stage.

3.6.8 corresponds to my native install. 3.7.2 looks to be the version built by bitbake.
I'll

What files do you need to replicate my build config?

[reid-p]

I add python3native to clang_git.bb

ie:
inherit cmake cmake-native
changed to
inherit cmake cmake-native python3native

and have got past the configure step.

Waiting for the do_compile

[kraj]

@reid-p thanks, can you create a pull?

[kraj]

should be fixed with 1746d05

@kraj
Took me a while to get a uild going, had to get a new host tool chain installed as it was failing in stage2 due to a warning about the age of the gcc compiler. Which looks to have been recently addressed.

Unfortunately still getting the failure.
