Hi all,

As I see in [1], when we prepare port for dde_rump, it fetches from [2] and not from [3]. And I found that the "src/sys/sys/common_ansi.h" is not present in [2]. May be for this reason while building sculpt the error came up. Also in [1] I can see that its fetching libc files from "/src/common/lib/libc/arch/aarch64/atomic" and not from "/src/common/lib/libc/arch/riscv/atomic". Is it okay or should I update this in [1] ?

[3] https://github.com/justincormack/netbsd-src

Were you suggesting to update this thing ? Please have a look and suggest steps I need to take.

I think this must be the reason for that fatal error. Kindly acknowledge.

Regards,

Pranab

When looking at "contrib/dde_rump-<hash>/src/lib/dde_rump_aarch64_backport" I
can see that only "src/sys/arch" [1] is checked out from [2] while
"common_ansi.h" resides under "src/sys/sys/common_ansi.h" [3]. Therefore, you
could adjust [1] to also checkout "src/sys" or "src/sys/sys" and update the
"INC_DIR" and/or symlinks under "dde_rump/lib/mk/spec/riscv" accordingly.

[1] repos/dde_rump/ports/dde_rump.port
[2] https://github.com/justincormack/netbsd-src
[3]
https://github.com/justincormack/netbsd-src/blob/master/src/sys/sys/common_ansi.h

*Note: When adjusting "dde_rump.port" you need to execute

! ./tool/ports/update_hash dde_rump

in order to create a new hash for the port.

Regards,

Sebastian
