undefined reference to `absl::lts_20230125::crc_internal::CrcCordState::CrcCordState

[rsehgalaka]

Hello,

I am trying to upgrade GRPC in my project from 1.48.0 to 1.53.0. I have made the required code changes and don't see any complication error but been stuck with this linking error. I think the library that has this "undefined symbol" is libabsl_strings which I am linking against as you can see below. Can someone please help me figure out how to resolve this linking issue? I am building on CentOS/gcc 7.3.1 if that helps. Thanks.

Building for CentOS..

Try adding -labsl_crc_cord_state since that is what defines CrcCordState:

abseil-cpp/absl/crc/CMakeLists.txt

You are likely running into what I described here: #1624 (comment)

You either need to build all of your code with -DNDEBUG or none of it.

[rsehgalaka]

Yeah, we don't use -DNDEBUG at all. Got any other pointers? The same build was working with GRPC 1.48.0.

[derekmauro]

Did you install Abseil with CMake using the Release configuration? If so, you used -DNDEBUG without knowing it. -DNDEBUG is standard for Release builds.

This is why I'm telling you to use a supported build system. https://abseil.io/resources/swe-book/html/ch18.html#what_happens_without_a_build_systemques

[rsehgalaka]

I didn't specify release configuration. Not sure what it defaults to when I follow instructions here

cmake -DgRPC_INSTALL=ON \
      -DgRPC_BUILD_TESTS=OFF \
      -DCMAKE_INSTALL_PREFIX=$MY_INSTALL_DIR \
      ../..

I found something very interesting. All my changes work fine on Ubuntu 18 (gcc 9.40) whereas on CentOS7 (gcc 7.3.1) they don't! Thanks for your help.
