[BUILD] Building simple example code with Bazel

[chenhong805]

Describe your environment Describe any aspect of your environment relevant to the problem, including your platform, build system, version numbers of installed dependencies, etc. If you're reporting a problem with a specific version of a library in this repo, please check whether the problem has been fixed on main branch.

OS: Linux ubuntu
Bazel version: Build label: 7.0.1

Steps to reproduce
Describe exactly how to reproduce the error. Include a code sample if applicable.

• successfully install opentelemetry onto system:
  git clone --recurse-submodules --depth 1 --branch v1.14.2 https://github.com/open-telemetry/opentelemetry-cpp.git && cd opentelemetry-cpp && mkdir build && cd build && cmake -DWITH_BENCHMARK=OFF -DWITH_ZIPKIN=ON .. && cmake --build . -j 16 && cmake --install .

• build this example with a bazel project with system dependencies:

# build rule:

cc_binary(
    name = "opentelemetry_test",
    srcs = ["opentelemetry_test.cpp"],
    copts = [
        "-I/usr/local/include/",
    ],
    # deps = ["//zipkip_opentelemetry:zipkin_opentelemetry"],
    linkopts = [
        "-L/usr/local/lib/",
        "-lcurl",
        "-lopentelemetry_common",
        "-lopentelemetry_trace",
        "-lopentelemetry_metrics",
        "-lopentelemetry_logs",
        "-lopentelemetry_version",
        "-lopentelemetry_resources",
        "-lopentelemetry_http_client_curl",
        "-lopentelemetry_exporter_ostream_span",
        "-lopentelemetry_exporter_ostream_metrics",
        "-lopentelemetry_exporter_ostream_logs",
        "-lopentelemetry_exporter_in_memory",
        "-lopentelemetry_exporter_zipkin_trace",
    ],
)

build command:

bazel build --verbose_failures --cxxopt=-std=c++14 //:opentelemetry_test

Additional context
Add any other context about the problem here.

Also try other version, same issue.
I found similar issue with CMake: #1359, but not sure how to fix in this example.

Thanks in advance!

I have BUILD file for this in my fork - https://github.com/malkia/opentelemetry-cpp/blame/main/examples/zipkin/BUILD - since it probably won't work here, here is a bit modified (hopefully still works)

package(default_visibility = ["//visibility:public"])

cc_binary(
    name = "example_zipkin",
    srcs = [
        "main.cc",
    ],
    linkopts = select({
        "//bazel:windows": [],
        "//conditions:default": ["-pthread"],
    }),
    tags = ["examples", "zipkin"],
    deps = [
        "//examples/common/foo_library:common_foo_library",
        "//exporters/zipkin:zipkin_exporter"
    ],
)

then you should be able to

bazel run example_zipkin

Thanks malkia.

I look into the cmake configuration and try build with -fPIC on the bazel target, found that libopentelemetry_common.so is not installed.

I added following build option and resolve the issue: -DOPENTELEMETRY_INSTALL=ON (see https://github.com/open-telemetry/opentelemetry-cpp/blob/main/sdk/CMakeLists.txt).

I feel this could be added to the documentation.
