[Barrelfish-users] Barrelfιsh build errors after update

[Georgios Varisteas]

Thanks I will try that later. I used libDeps and thought it should be enough. Am am indeed using ahci and it is functioning well, speeding up everything inside qemu and other emulators.

cheers,
Georgios

In this case the linker can't find the vfsfd library, and I can't see it
in the gcc command line. If were using the libDeps function, it should
had added it. In any case, I think just adding the library in the
dependencies should fix the problem this time.

Note #1: If you add the library dependency manually, note that ordering
matters. I would try putting vfsfd after vfs.

Note #2: Are you using ahci to access files on disks?

cheers,
Kornilios.
