protocol buffers plugin with C++

[Graham Walsh]

Hi,

Im trying to build an example protoc plugin... the abseil dependencies are a nightmare. (link order).

How do I build the example protocol buffer plugin? I need the link order for the abseil libs... here....

g++ -I../protobuf/third_party/abseil-cpp -I../protobuf/src/     ./my_prot
oc_plugin.cc -o my_protoc_plugin  ../protobuf/build/libprotoc.a  ../protobuf/build/libprotobuf.a  abseil/libabsl_base.a
abseil/libabsl_strings.a abseil/libabsl_flags_internal.a abseil/libabsl_hash.a      -ldl -lpthread


Chasing these down (adding various abseil static libs) ... just takes me down a rabbit hole.

What the exact link order to use abseil static libs protoc plugin (please dont say bezel) I need the command line and link order for the static libs.
