Running that through c++filt I see:

deepmind::reverb::Table::Table(std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::shared_ptr<deepmind::reverb::ItemSelector>, std::shared_ptr<deepmind::reverb::ItemSelector>, long, int, std::shared_ptr<deepmind::reverb::RateLimiter>, std::vector<std::shared_ptr<deepmind::reverb::TableExtension>, std::allocator<std::shared_ptr<deepmind::reverb::TableExtension> > >, std::optional<tensorflow::StructuredValue>)
deepmind::reverb::Table::Table(std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::shared_ptr<deepmind::reverb::ItemSelector>, std::shared_ptr<deepmind::reverb::ItemSelector>, long, int, std::shared_ptr<deepmind::reverb::RateLimiter>, std::vector<std::shared_ptr<deepmind::reverb::TableExtension>, std::allocator<std::shared_ptr<deepmind::reverb::TableExtension> > >, std::optional<tensorflow::StructuredValue>)

And you're looking for:

deepmind::reverb::Table::Table(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::shared_ptr<deepmind::reverb::ItemSelector>, std::shared_ptr<deepmind::reverb::ItemSelector>, long, int, std::shared_ptr<deepmind::reverb::RateLimiter>, std::vector<std::shared_ptr<deepmind::reverb::TableExtension>, std::allocator<std::shared_ptr<deepmind::reverb::TableExtension> > >, std::optional<tensorflow::StructuredValue>)'

The only difference I see is the std::_cxx11 for basic_string. When we build Reverb release mode we use some variant of the following build flags:

--cxxopt="-D_GLIBCXX_USE_CXX11_ABI=0"
--cxxopt="-std=c++14"
--copt="-Wall" --copt="-Wno-sign-compare"
--linkopt="-lrt -lm"
--copt=-mavx --copt=-DEIGEN_MAX_ALIGN_BYTES=64

You probably want to use some or all of these. In particular, i'm guessing our disabling cxx11_abi is causing the difference in the signatures causing linker failure?

Please provide an ldd or objdump of libtable.so run through c++filt so we can match the signatures.

@ebrevdo Thanks for taking a look. I'm not familiar with the usage of ldd or c++filt.

$ ldd /home/xander/dev/reverb/bazel-bin/reverb/cc/libtable.so
        linux-vdso.so.1 (0x00007ffc2b9c1000)
        librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f67fde98000)
        libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f67fdafa000)
        libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f67fd6ed000)
        libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f67fd4d5000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f67fd0e4000)
        libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f67fcec5000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f67fe0a0000)

This is showing the libraries that libtable.so is linked against, but not function signatures.

I see I have c++filt on my Ubuntu system and usage is described here. How does this relate to ldd's output?
Is there a specific flag on objdump that will give us what we're looking for?

If we're looking for symbols, I've got this:
