[cfe-dev] How to configure clang to use arm-none-eabi linker

[Kyriakos Georgiou via cfe-dev]

Hi Jonathan,


I manage to configure and build by specifying were the libraries are by using the -L option.


Thank you very much!,

Kyriakos

And where do your -lc / -lm live? I don't see a `--sysroot=`.
