Re: [Minios-devel] [UNIKRAFT/NEWLIB PATCH 08/16] sys/un.h: Import from musl

[Charalampos Mainas <Charalampos.Mainas@xxxxxxxxx>]

Hello Costin,

Unfortunately, I get a compilation error when using sys/un.h header. There is no features.h header in Unikraft which It seems is needed for sa_family_t type in struct sockaddr_un.

Thank you,
Charalampos Mainas
