idk why this happened
bash build_stage1.sh terraos
and that happened

upon further research, i found this on the buildroot bug tracker
bug report
DescriptionRicardo Miguel 2024-06-04 00:18:49 UTC
When trying to build root image for zynq target, it throws this error:
....
../src/tramp.c: In function 'ffi_tramp_get_temp_file':
../src/tramp.c:262:22: error: implicit declaration of function 'open_temp_exec_file' [-Wimplicit-function-declaration]
262 | tramp_globals.fd = open_temp_exec_file ();
....
Host OS: Fedora 40
Kernel: 6.8.10-300.fc40.x86_64
gcc : version 14.1.1 20240522 (Red Hat 14.1.1-4) (GCC)

Problem: libffi-3.4.4 does not compile with gcc > 14.

Solution:

1. Edit buildroot-2024.02.2/package/libffi/libffi.mk and change libffi version
   LIBFFI_VERSION = 3.4.6

2. Edit buildroot-2024.02.2/package/libffi/libffi.hash and change hashes:

For libffi-3.4.6.tar.gz

sha256 b0dea9df23c863a7a50e825440f3ebffabd65df1497108e5d437747843895a4e libffi-3.4.6.tar.gz

I have tried it only for zynq target, but I assume that this fix works for all
targets that compile libffi and all systems where GCC > 14
Regards

must be a buildroot issue lol

[appleflyerv3]

therefore, a possible fix for this issue is to edit buildroot-2024.02.2/package/libffi/libffi.mk
and change libffi version
LIBFFI_VERSION = 3.4.6

then, change the hash

created a pull request on your fork of buildroot to fix this issue

[happylabdab2]

compile it on ubuntu the go to arch

[appleflyerv3]

iirc bootstrapping arch linux needs arch linux so id go with archlinux

[appleflyerv3]

issue fixed with r58 updating buildroot repo from upstream 🔥
