Comment 3 A. Wilcox (awilfox) 2016-12-30 02:14:49 UTC
I'm not sure how this was stabled on ARM or PowerPC, as neither architecture ships a.out.h in their linux-headers packages.

I have a patch that corrects the inclusion to only occur when a.out support is enabled, but I will also need to add IUSE=aout to the ebuild.  Then that USE will need to be masked on architectures where it isn't supported.

Or, I can just blanket-disable a.out support in the ebuild since such binaries are very old and unsupported.

Comment 4 Felix Janda 2016-12-30 09:04:07 UTC
The patch from the musl overlay added the hacky <linux/a.out.h>
include. The KEYWORDS of ebuilds of the musl overlay usually mirror
those of the main tree.

libbsd uses <a.out.h> only to implement nlist(). Even when a.out
support is disabled, the implemented nlist function still needs the
definitions of struct nlist, N_UNDF, N_ABS, N_TEXT, N_DATA, N_BSS,
N_FN, N_EXT from a.out.h because it needs to convert Elf_Sym to struct
nlist (to match the API of nlist()).

Maybe upstream can be convinced to include these few definitions
in their headers. Could you open an upstream bug?
Comment 5 Pacho Ramos gentoo-dev 2018-09-23 13:33:31 UTC
can you retry with 0.9.1?
