opentelemetry-cpp: undefined reference to `opentelemetry::v1::sdk::common

Hi Everyone,

A few days ago I’m trying to compile a simple hello world application(cpp), after the saga of the compilation of opentelemetry cpp SDK, I’m having the following error when running make:

/usr/bin/ld: /opt/otelcpp/lib/libopentelemetry_trace.a(random_id_generator.cc.o): in function opentelemetry::v1::sdk::trace::RandomIdGenerator::GenerateSpanId()': random_id_generator.cc:(.text+0x41): undefined reference to opentelemetry::v1::sdk::common::Random::GenerateRandomBuffer(opentelemetry::v1::nostd::span<unsigned char, 18446744073709551615ul>)’ /usr/bin/ld: /opt/otelcpp/lib/libopentelemetry_trace.a(random_id_generator.cc.o): in function opentelemetry::v1::sdk::trace::RandomIdGenerator::GenerateTraceId()': random_id_generator.cc:(.text+0xc7): undefined reference to opentelemetry::v1::sdk::common::Random::GenerateRandomBuffer(opentelemetry::v1::nostd::span<unsigned char, 18446744073709551615ul>)’ /usr/bin/ld: /opt/otelcpp/lib/libopentelemetry_exporter_jaeger_trace.a(THttpTransport.cc.o): in function opentelemetry::v1::exporter::jaeger::THttpTransport::THttpTransport(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::multimap<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, opentelemetry::v1::ext::http::client::cmp_ic, std::allocator<std::pair<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > > > >)': THttpTransport.cc:(.text+0xb6): undefined reference to opentelemetry::v1::ext::http::client::HttpClientFactory::CreateSync()’ collect2: error: ld returned 1 exit status make[2]: *** [CMakeFiles/hello-otel.dir/build.make:113: hello-otel] Error 1 make[1]: *** [CMakeFiles/Makefile2:83: CMakeFiles/hello-otel.dir/all] Error 2 make: *** [Makefile:91: all] Error 2
