The php-pecl-dbus encouters two build issues in both buildroot 2025.02.x
and master branch, both related to PHP8 and GCC14:
/home/alexis/src/buildroot/php/build/php-pecl-dbus-b147624d480c3353e6c700e9a2d0c6f14d853941/dbus.c:465:56:
error: assignment to ‘zend_object_get_properties_t’ {aka ‘struct
_zend_array * (*)(struct _zend_object *)’} from incompatible pointer
type ‘HashTable * (*)(zval *)’ {aka ‘struct _zend_array * (*)(struct
_zval_str
uct *)’} [-Wincompatible-pointer-types]
465 | dbus_object_handlers_dbus_array.get_properties =
dbus_array_get_properties;
| ^
[...]
The build failure can be reproduced with this minimal defconfig:
BR2_arm=y
BR2_cortex_a9=y
BR2_ARM_ENABLE_NEON=y
BR2_ARM_ENABLE_VFP=y
BR2_ARM_FPU_NEON=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
BR2_PACKAGE_PHP=y
BR2_PACKAGE_PHP_PECL_DBUS=y
This build failure is the result of two events/conditions:
- the update to PHP8 has changed the prototype for
zend_object_read_property_t and zend_hash_get_current_key(see [1]).
But at this time, php-dbus just generated a new warning
(-Wincompatible-pointer-types)
- using bootlin bleeding-edge toolchain brings in GCC14, which now turns
this warning into a systematic error (see [2])
Bring the relevant patches to fix this build.
The first patch comes from an already opened PR on the upstream source.
The second patch has been written during the build failure
investigation, and has been sent upstream as well.
