protobuf-c-1.3.1:20190620-142231.log

After updating to protobuf-3.7.1, protobuf-c fails to rebuild with this error:

[libprotobuf WARNING /var/tmp/portage/dev-libs/protobuf-3.7.1/work/protobuf-3.7.1/src/google/protobuf/compiler/parser.cc:564] No syntax specified for the proto file: t/issue220/issue220.proto. Please use 'syntax = "proto2";' or 'syntax = "proto3";' to specify a syntax version. (Defaulted to proto2 syntax.)

Looks like it's linked to the gold linker. Switching to ld.bfd temporarily let's me rebuild protobuf-c succesfully.

Do you mean that you rebuilt dev-libs/protobuf or dev-libs/protobuf-c with linker BFD?

[Comment 3 Bernd 2019-06-20 17:48:41 UTC]

No, only protobuf-c was rebuilt using BFD linker.

[Comment 4 Skruppy 2019-07-07 16:58:47 UTC]

As a workaround, the following worked for me:

echo 'LDFLAGS="${LDFLAGS} -Wl,-fuse-ld=bfd"' >>/etc/portage/env/force-bfd.conf
echo 'dev-libs/protobuf-c force-bfd.conf' >>/etc/portage/env/package.env/issue-688394
