Description Ricardo 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
sha256  67894089811f93fca47a76f85e017da6f8582d4ba0905963c6e0f1ad6df7a195  LICENSE

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
