Hi Edwin,

Étoilé questions are better directed to one of the Étoilé lists (probably etoile-dev in this case), however:

It looks like you are using a broken libstdc++.  Can you either downgrade your libstdc++ or use libc++?

You may find that LanguageKit has some issues with Linux at the moment.  I believe that some of the function attribute code for defining the calling convention is not correctly updated for Linux. Niels would know more.

OK, I will continue this on etoile-dev.
I don't like the idea of downgrading libstdc++, I'm afraid running into all kind of other problems, since I'm not a linux specialist.
 
I installed libc++, as indicated on the LLVM website. But this gives the same errors.

Is it necessary to change the makefiles for Etoilé, as is indicated in the examples on the LLVM pages:
clang++ -stdlib=libc++ helloworld.cpp -lcxxrt

Thanks in advance.
