Scarthgap native build errors

Scarthgap native build errors

[Rudolf J Streif]

I am building on Fedora Core 42 with gcc 15.1. I am currently seeing two 
strange errors when building native packages for cmake-native and 
git-native:

cmake-native:

tcu-firmware/build/tmp/work/x86_64-linux/cmake-native/3.28.3/cmake-3.28.3/Utilities/cmcppdap/include/dap/network.h:31:39: 
error: ‘uint32_t’ has not been declared
|    31 |                                       uint32_t timeoutMillis = 0);
|       |                                       ^~~~~~~~

This can of course easily be fixed by including <cstdint>. However, it's 
still strange that this is happening and it's the first time that I am 
seeing this.


git-native:

| reflog.c:211:104: error: macro ‘unreachable’ passed 3 arguments, but 
takes just 0
|   211 | static int unreachable(struct expire_reflog_policy_cb *cb, 
struct commit *commit, struct object_id *oid)
| | ^
| In file included from git-compat-util.h:225,
|                  from reflog.c:1:
| /usr/lib/gcc/x86_64-redhat-linux/15/include/stddef.h:468:9: note: 
macro ‘unreachable’ defined here
|   468 | #define unreachable() (__builtin_unreachable ())
|       |         ^~~~~~~~~~~

The weird thing with this issue is that line 211 in reflog.c declares 
the function unreachable() with three parameters. However, the compiler 
interprets it as the macro unreachable for stddef.h being called. 
Unfortunately, I don't have a solution for this.


Thanks,
Rudi

Looking at your cmake version, you are on Scarthgap.
Fedora Core 42 is not a supported distribution for Scarthgap :
https://docs.yoctoproject.org/5.0.10/ref-manual/system-requirements.html#supported-linux-distributions
So, the official solution is to use a supported build OS (as a container
for example).

FYI, Fedora Core 42 is not even tested on master right now so it is
definitely too recent for scarthgap.

[Martin Jansa]

FWIW: ubuntu-25.10 (which I happen to use in docker for some of
scarthgap builds) snapshot switched to gcc-15 last week as well, so
I've sent fixes for these (cmake and git will be sent later today)
