Even with an upstream patch from protobuf v3.3 [1], the build fail with another issue:
In file included from google/protobuf/dynamic_message.cc:80:
./google/protobuf/map_field.h: In member function 'void google::protobuf::internal::MapField<Key, T, key_wire_type, value_wire_type, default_enum_value>::Swap(google::protobuf::internal::MapFieldLite<Key, T, kKeyFieldType, kValueFieldType, default_enum_value>*)':

Add a dependency on gcc >= 4.5.

# On PowerPC, the __atomic_*() built-ins for 1-byte, 2-byte and 4-byte
|
|
# types are available built-in. However, the __atomic_*() built-ins for
|
|
# 8-byte types is implemented via libatomic, so only available since gcc
|
|
# 4.8.
|
|
#
|
|
# In Buildroot, to simplify things, we've decided to simply require gcc
|
|
# 4.8 as soon as the architectures has at least one __atomic_*() built-in
|
|
# variant that requires libatomic.
|
|
#
|
|
# Since protobuf most likely only uses the 1, 2 and 4-byte variants, it
|
|
# *could* technically build with gcc 4.7. This is probably not a big deal,
|
|
# and we can live with requiring gcc 4.8 on PowerPC to build protobuf.
|
|
#
|
|
# host-protobuf only builds on certain architectures
