System: NetBSD Build-0 10.99.15 NetBSD 10.99.15 (GENERIC) #1: Tue Jul 29 12:42:32 CEST 2025 kardel@gaia:/src/NetBSD/current/src/obj.amd64/sys/arch/amd64/compile/GENERIC amd64
Architecture: x86_64
Machine: amd64
>Description:
In 10.99.15 following ELF include sequence fails
#include <elf.h>
#include <libelf.h>
#include <gelf.h>
int main() { return 0; }
errors are:
n file included from /usr/include/elfdefinitions.h:34,
from /usr/include/libelf.h:40,
from test.c:2:
/usr/include/sys/elfdefinitions.h:2586:3: error: conflicting types for 'Elf32_Cap'; have 'struct <anonymous>'
2586 | } Elf32_Cap;
| ^~~~~~~~~
In file included from test.c:1:
/usr/include/elf.h:743:3: note: previous declaration of 'Elf32_Cap' with type 'Elf32_Cap'
743 | } Elf32_Cap;
| ^~~~~~~~~
/usr/include/sys/elfdefinitions.h:2595:3: error: conflicting types for 'Elf64_Cap'; have 'struct <anonymous>'
2595 | } Elf64_Cap;
| ^~~~~~~~~
/usr/include/elf.h:751:3: note: previous declaration of 'Elf64_Cap' with type 'Elf64_Cap'
751 | } Elf64_Cap;
| ^~~~~~~~~
/usr/include/sys/elfdefinitions.h:2622:3: error: conflicting types for 'Elf32_Dyn'; have 'struct <anonymous>'
2622 | } Elf32_Dyn;
| ^~~~~~~~~
/usr/include/elf.h:762:3: note: previous declaration of 'Elf32_Dyn' with type 'Elf32_Dyn'
762 | } Elf32_Dyn;
| ^~~~~~~~~
... many more
when removing #include <elf.h> the compilation succeeds.
On NetBSD 10.1_STABLE and versions before that including elf.h is not leading to errors.
This looks like a source code compatibility regression. The include sequence also works on other operating Sytems (Linux, Solaris, ...)
>How-To-Repeat:
attempt to compile in 10.99.15:
#include <elf.h>
#include <libelf.h>
#include <gelf.h>
int main() { return 0; }
>Fix:
revisit and fix elf includes

Log Message:
PR/59564: Frank Kardel: Allow elfdefinitions.h and elf.h to co-exist.
Unfortunately c does not allow structure redefinitions, even if the structures
are identical. So include <sys/exec_elf.h> from <sys/elfdefinitions.h> and
protect all the typedefs that exec_elf.h already provides with the guard
of the sys/exec_elf.h file.
Also fix the order of the cap union fields so that the sys/sys_exec.h and
sys/elfdefinitions.h are identical.

Log Message:
Allow code to include either (or both) of <sys/elfdefinitions.h> and
<sys/exec_elf.h>, in any order.
This is a work-around to address PR lib/59564 (build breakage when
both of these files are #included).
With this changeset, whichever file gets included first 'wins'.
Prior changes in NetBSD and upstream at Elftoolchain have aligned the
'generic' ELF definitions in NetBSD's <sys/exec_elf.h> with those
in Elftoolchain's <sys/elfdefinitions.h>, so that either file can
be used interchangeably when building NetBSD.
This changeset also removes prior workarounds in the source tree
for this issue.

src/include: elf.h
Log Message:
Implement an up to date and cross-platform <elf.h> for userland use.
With this change:
- Elftoolchain's <sys/elfdefinitions.h> is used for the definitions
that make up the ELF gABI and its processor-specific ABI
supplements.
- Existing NetBSD-local definitions are brought in via
the kernel header <sys/exec_elf.h>, for continuity.
This changeset prepares the ground for migrating userland-only
definitions out of the kernel header, for better separation
of concerns.
This changeset also eases the development of cross-architecture
ELF tools since <elf.h> now offers ELF-related constants for all
of the architectures that NetBSD currently supports.

These changes seem to have broken builds of some software. With HEAD

Apologies for the breakage.
The definition of Elf{32,64}_Versym was changed in -CURRENT ([1])
to align its definition with other ELF toolkits (and with the
file format).
There are two compile-time guards that could be used to compile
around this change:
a) a bump of __NetBSD_version__ ([2]),
b) increment to an inclusion guard ([3]).

I don't know if the latest change has broken something else, but we
have a couple copies of integrated abseil copies in pkgsrc that we
have fixed with versions of
devel/abseil/patches/patch-absl_debugging_internal_elf__mem__image.cc
- perhaps firefox140 needs that too?

Yes, I discovered that, too, and have fixed firefox140 now as well.
