[Barrelfish-users] Barrelfιsh build errors after update

[Georgios Varisteas]

Hi Kornilios,

I thought of posixcompat myself, this existed with oldc also and if you check the actuall gcc command (included in my initial email) you can see that it is included. Is it possible that it is a library linking order problem? If I'm
not mistaken libs are linked in reverse order, right?

Anyway, posixcompat is included automatically and it is not the source of the error.

cheers,
Georgios Varisteas

AFAICT your application is using locales, which requires open() and
friends. These are included in the posixcompat library. Adding a
"posixcompat" in libDeps should do the trick.

cheers,
Kornilios.
