I am trying to build a go_binary that depends on com_github_pebbe_zmq4, a go wrapper of the libzmq in C++. I've been struggling to make pebbe/zmq4 "see" zmq.h in libzmq, and can't make it work after trying multiple approaches:
Approach 1. Building using libzmq from Bazel Central Registry:
load("@rules_go//go:def.bzl", "go_binary")go_binary( name = "zmq_client", srcs = ["zmq_client.go"], deps = ["@com_github_pebbe_zmq4//:go_default_library", ], cgo = True, cdeps = [ # Including the full library doesn't make it work, either. # "@libzmq//:libzmq","@libzmq//:libzmq_headers_only", ],)Link: Minimal code example on Github
Approach 2. Building libzmq using rules_foreign_cc:
load("@rules_foreign_cc//foreign_cc:defs.bzl", "cmake")load("@rules_go//go:def.bzl", "go_binary")cmake( name = "zmq", lib_source = "@zeromq//:all_srcs", out_static_libs = ["libzmq.a"],)go_binary( name = "zmq_client", srcs = ["zmq_client.go"], deps = ["@com_github_pebbe_zmq4//:go_default_library", ], cgo = True, cdeps = [":zmq", ],)Link: Minimal code example on Github
What am I missing? I've read through go_binary and rules_foreign_cc docs multiple times but can't find the right way, also tried the Bazel Slack #Go channel here, but haven't found out the solution yet.
