Undefined reference error while building simple example #2188

Open TheOxFromOutOfTheBox opened 1 year ago

TheOxFromOutOfTheBox commented 1 year ago

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 - SUSE Linux Enterprise Server 15 Installed opentelemetry-cpp[otlp-grpc] through vcpkg.

Steps to reproduce Describe exactly how to reproduce the error. Include a code sample if applicable. I ran a slightly modified version of the simple example given in the repository.

g++ trial.cpp -std=c++14 -I vcpkg/packages/opentelemetry-cpp_x64-linux/include/ && ./a.out
#include "opentelemetry/exporters/ostream/span_exporter_factory.h"
#include "opentelemetry/sdk/trace/simple_processor_factory.h"
#include "opentelemetry/sdk/trace/tracer_provider_factory.h"
#include "opentelemetry/trace/provider.h"

namespace trace_api      = opentelemetry::trace;
namespace trace_sdk      = opentelemetry::sdk::trace;
namespace trace_exporter = opentelemetry::exporter::trace;

namespace
{
void InitTracer()
{
  auto exporter  = trace_exporter::OStreamSpanExporterFactory::Create();
  auto processor = trace_sdk::SimpleSpanProcessorFactory::Create(std::move(exporter));
  std::shared_ptr<opentelemetry::trace::TracerProvider> provider =
      trace_sdk::TracerProviderFactory::Create(std::move(processor));

  // Set the global trace provider
  trace_api::Provider::SetTracerProvider(provider);
}

void CleanupTracer()
{
  std::shared_ptr<opentelemetry::trace::TracerProvider> none;
  trace_api::Provider::SetTracerProvider(none);
}
}  // namespace

int main()
{
  // Removing this line will leave the default noop TracerProvider in place.
  InitTracer();

    auto provider = trace_api::Provider::GetTracerProvider();
    auto tracer = provider->GetTracer("foo_library");

  //create a span
    auto span = tracer->StartSpan("first-span");
    auto scope = tracer->WithActiveSpan(span);
    //inner ops
    std::this_thread::sleep_for(std::chrono::milliseconds(100));
    span->End();

    std::cout<<"Heloworld!"<<std::endl;
    CleanupTracer();
    return 0;
}

What is the expected behavior? What did you expect to see? The program should compile without errors and execute.

What is the actual behavior? What did you see instead? The program passes syntax and lexical analysis , and fails during machine code generation, with the error

 /tmp/ccdjnFU7.o: In function `(anonymous namespace)::InitTracer()':

You may also need to link all components you use of otel-cpp. Alternatively, you can use cmake to automatically link them if you are using vcpkg.

TheOxFromOutOfTheBox commented 1 year ago

Hi owent, I tried to make a CMakeLists.txt

include_directories(${CMAKE_SOURCE_DIR}/exporters/ostream/include)

target_link_libraries(opentelemetry_exporter_ostream_span ${CMAKE_THREAD_LIBS_INIT} opentelemetry_api)

add_executable(example_simple main.cc)
target_link_libraries(example_simple ${CMAKE_THREAD_LIBS_INIT} opentelemetry_trace)

However I get the error while doing cmake 

CMake Error at CMakeLists.txt:5 (target_link_libraries):
  Cannot specify link libraries for target
  "opentelemetry_exporter_ostream_span" which is not built by this project.

This is presumably because it cant find the libraries,due to it being in different folders. But I'm at a loss as to how to provide reference to the folder image This is my folder structure, and my otel is inside vcpkg/packages.

Thanks for the quick reply.

owent commented 1 year ago

In cmake, you can use find_package(opentelemetry-cpp) to find otel-cpp and use target_link_libraries(example_simple opentelemetry-cpp::ostream_span_exporter) to link it.

TheOxFromOutOfTheBox commented 1 year ago

Hey, I'm trying to build a cmake file with the help of https://github.com/open-telemetry/opentelemetry-cpp/issues/1359 but my build keeps failing saying it cant find absl while i do have abseil installed.

So, on further research I realized I had to remove the absl installed before in usr/local in order to use the one vcpkg installed so I added it to the CMAKE_IGNORE_PATH variable.

My updated CMakeLists.txt

cmake_minimum_required(VERSION 3.17)
project(otel-test)

set(CMAKE_PREFIX_PATH "../vcpkg/packages/;/home/kmh/vcpkg/packages/abseil_x64-linux/share;/home/kmh/vcpkg/packages/openssl_x64-linux/")

add_executable(example_simple test.cpp)
target_link_libraries(example_simple ${CMAKE_THREAD_LIBS_INIT} opentelemetry::opentelemetry_trace)

That takes me past the absl error however I now face an OpenSSL include error.

CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:164 (message):

Changing the OPENSSL_ROOT_DIR variable however doesn't have any effect, as you can see in line 10 of my CMakeLists.txt

I was also checking out another way to link all libraries via g++ itself, and I ran into this

g++ -I/home/kmh/vcpkg/packages/opentelemetry-cpp_x64-linux/include/ test.cpp -o program -L/home/kmh/vcpkg/installed/x64-linux/lib/ $(ls /home/kmh/vcpkg/installed/x64-linux/lib/ | grep '\.a$' | sed 's/lib/-l/' | sed 's/\.a//')

I'm really at a loss as to what to do next. There are multiple references to absl and Bad Variant access?

find_package(abseil REQUIRED)

find_package(OpenSSL REQUIRED) is also required if you want to use OTLP exporters or http client.

I was also checking out another way to link all libraries via g++ itself, and I ran into this

g++ -I/home/kmh/vcpkg/packages/opentelemetry-cpp_x64-linux/include/ test.cpp -o program -L/home/kmh/vcpkg/installed/x64-linux/lib/ $(ls /home/kmh/vcpkg/installed/x64-linux/lib/ | grep '\.a$' | sed 's/lib/-l/' | sed 's/\.a//')

I'm really at a loss as to what to do next. There are multiple references to absl and Bad Variant access?

The link order should be carefully considered.

TheOxFromOutOfTheBox commented 1 year ago

Hi owent, Regarding your comment about link order, I only decided to compile with the .a files I need. Here's my current compile statement.

g++ -I /home/kmh/vcpkg/packages/opentelemetry-cpp_x64-linux/include/ test.cpp ../vcpkg/installed/x64-linux/lib/libopentelemetry_trace.a ../vcpkg/installed/x64-linux/lib/libopentelemetry_exporter_ostream_span.a ../vcpkg/installed/x64-linux/lib/libopentelemetry_common.a ../vcpkg/installed/x64-linux/lib/libabsl_bad_variant_access.a ../vcpkg/installed/x64-linux/lib/libopentelemetry_resources.a  ../vcpkg/installed/x64-linux/lib/libopentelemetry_version.a ../vcpkg/installed/x64-linux/lib/libopentelemetry_exporter_ostream_logs.a ../vcpkg/installed/x64-linux/lib/libopentelemetry_exporter_ostream_metrics.a ../vcpkg/installed/x64-linux/lib/libopentelemetry_logs.a ../vcpkg/installed/x64-linux/lib/libopentelemetry_metrics.a

This removes most of the errors, including absl and the initial span exporter factory error.However some still remain.

These are mostly related to only two things

However, I've already included all the relevant files for resources, and all the otel-ostream-exporters. Where else can I find them?

TheOxFromOutOfTheBox commented 1 year ago

So, update.With the g++ thing, the problem was the ordering of the included libs. Final run command

g++ -I /home/kmh/vcpkg/packages/opentelemetry-cpp_x64-linux/include/ ostreamspan.cpp ../vcpkg/installed/x64-linux/lib/libopentelemetry_version.a ../vcpkg/installed/x64-linux/lib/libopentelemetry_exporter_ostream_span.a ../vcpkg/installed/x64-linux/lib/libopentelemetry_resources.a ../vcpkg/installed/x64-linux/lib/libopentelemetry_trace.a ../vcpkg/installed/x64-linux/lib/libopentelemetry_common.a ../vcpkg/installed/x64-linux/lib/libabsl_bad_variant_access.a  ../vcpkg/installed/x64-linux/lib/libopentelemetry_exporter_ostream_logs.a ../vcpkg/installed/x64-linux/lib/libopentelemetry_exporter_ostream_metrics.a ../vcpkg/installed/x64-linux/lib/libopentelemetry_logs.a ../vcpkg/installed/x64-linux/lib/libopentelemetry_metrics.a

However, this seems to be too difficult if I even move towards OTLP GRPC, with it including many absl libs,not to mention others like protobuf, grpc and the rest.

So, CMake is the only viable option, however I'm no close to building with the help of the earlier comment as that does not take care of the openSSL issue.It gives me the same error.

owent commented 1 year ago

We have many users using other build system confuse about the linking problem before. Can we add a tool in cmake to make a all in one static library file on Linux and Mac, just like all in one dll on Windows? What's your thoughtsa about this? @open-telemetry/cpp-maintainers

Can we add a tool in cmake to make a all in one static library file on Linux and Mac, just like all in one dll on Windows?

Good point. But I feel this will make maintenance difficult. Single DLL support was added to handle special case for difficult in sharing symbols across multiple DLLs.

I am using ar to create an archive called libopentelemetry_packed.a, which contains all the .a files from libopentelemetry_*.a in our internal version of otel-cpp. This archive is approximately 280MB in size when built in RelWithDebInfo mode, and it can only be exported manually. Therefore, I'm wondering whether it is worth doing.

I know that usually the .cmake file is in /share folder, however mine doesn't have that

If I try to link the libraries directly as I have been advised not to, I still get the error I posted in my previous comment.

Update number 2:

I was able to see on running nm /home/kmh/vcpkg/installed/x64-linux/lib/libcrypto.a | grep "EVP_DigestSignU" and similar for the other one that these symbols were there in the .a lib files that were built, however my cmake still doesn't work.

On running cmake --build . --verbose I found that its linking the openssl library from usr/local as well as the .a files I added so it must be an ordering issue of sorts.

However I'm unable to remove the flag from the compilation, after trying

The g++ command gives even more undefined reference errors, even though I could find those symbols in the files.

Part of the error:

I'm not sure the problem in your system. But I have a ci job to use vcpkg to import otel-cpp's dependencis and it works well.(All packaged are imported by find_package(...))

cmake will try to find package in PATH, this document may help https://cmake.org/cmake/help/v3.27/command/find_package.html.

TheOxFromOutOfTheBox commented 1 year ago

hey owen, I'm not sure I understand what I should do. could you share the cmake file for the gcc+vcpkg ci job that you are running?that would be very helpful in testing whether the issue is in my system or with my current vcpkg installation

Sorry for the delay, the sample is a bit complicated https://github.com/atframework/cmake-toolset/blob/main/ci/do_ci.sh#L232

TheOxFromOutOfTheBox commented 1 year ago

Hey owen, Sorry for the delay on my end. I still couldn't get find_package to recognize libssl.a and libcrypto.a , so I had to end up using the output from cmake --build . --verbose and end up reordering the libs.

The issue that I've found is that opentelemetry-cpp and its libs make use of grpc, which in turn makes use of openssl . However when I add target_link_libraries pointing directly to the absolute paths of the ssl libs, they are placed before the libgrpc files are included, leading to undefined reference errors.Moving the order of libssl.a and libcrypto.a led me to being able to compile the program.

However this is still not a feasible way.How would I go around changing up the order in cmake?

The final compilation command as a Makefile

# the compiler: gcc for C program, define as g++ for C++
CC = g++

# compiler flags:
#  -g     - this flag adds debugging information to the executable file
#  -Wall  - this flag is used to turn on most compiler warnings

Could you try to use --debug-find-pkg=OpenSSL to find out why openssl can not be found?

TheOxFromOutOfTheBox commented 1 year ago

Should I be running that in the command line or somewhere in the cmake file?

The is option can be added in command line.It's not a variable in cmake file.

The packages needed depdend how you compile otel-cpp. If you compile otel-cpp without openssl, find_package(OpenSSL) is not required. I think maybe it's better to install the missing packages if you use vcpkg to manage packages.

Facing same issue since I vcpkg updated to 1.16.x, unchanged code worked fine on 1.14.x and earlier.

@TheOxFromOutOfTheBox In my understanding, You may need include("${CMAKE_TOOLCHAIN_FILE}") if you set CMAKE_TOOLCHAIN_FILE after project(otel-test). Setting this variable does nothing after toolchains is already detected.

The better way to use toolchain file is use -DCMAKE_TOOLCHAIN_FILE=${VCPKG_ROOT}/scripts/buildsystems/vcpkg.cmake in commandline or you can try to set it before project sentence.
