undefined reference to `fmt::v7::detail::vformat[abi:cxx11](fmt::v7::basic_string_view<char>, fmt::v7::format_args)'

[gkamendje]

I have the following lines of codes in an application (OpenRoad https://github.com/The-OpenROAD-Project/OpenROAD/blob/master/src/gpl/test/fft_test.cc)

  for (int y = 0; y < Y_MAX; y++) {
    for (int x = 0; x < X_MAX; x++) {
      auto eForce = fft->getElectroForce(x, y);
      auto electroPhi = fft->getElectroPhi(x, y);
      out_ef_1st << fmt::format(
          "    {: 26.20f}, // {:d}, {:d}\n", eForce.first, x, y);
      out_ef_2nd << fmt::format(
          "    {: 26.20f}, // {:d}, {:d}\n", eForce.second, x, y);
      out_el_phi << fmt::format(
          "    {: 26.20f}, // {:d}, {:d}\n", electroPhi, x, y);
    }
  }

Compiling this code on openSUSE Leap 15.5 works well. However, I get the following error message on openSUSE Leap 15.6

I am using spdlog version 1.8.1. Looking at the libspdlog.a library, I see the following

Spdlog was build with the following options: cmake -DCMAKE_INSTALL_PREFIX="${spdlogPrefix}" -DCMAKE_POSITION_INDEPENDENT_CODE=ON -DSPDLOG_BUILD_EXAMPLE=OFF

I have no clue what is going on.

Does LD_LIBRARY_PATH include “${spdlogPrefix}”?
If not, another libspdlog.a may be linked.

Other possibilities following:

• Incompatibility with ABI
• Wrong order of linking libraries
