Thanks! Unfortunately I still get a lot of linker errors using the repro from JIRA, but at least the Abseil issues are eliminated. I think the remaining issues are just because of the order of libraries/needing to repeat libraries. This is what CMake generates, which fails with linker errors: ``` /usr/bin/c++ -O3 -DNDEBUG CMakeFiles/arrow_example.dir/example.cc.o -o arrow_example /home/lidavidm/Code/upstream/arrow-14708/install/lib/libarrow.a /home/lidavidm/Code/upstream/arrow-14708/install/lib/libarrow_flight.a -pthread /usr/lib/x86_64-linux-gnu/libssl.so /usr/lib/x86_64-linux-gnu/libcrypto.so -lrt /home/lidavidm/Code/upstream/arrow-14708/install/lib/libarrow_bundled_dependencies.a ``` The errors indicate `libarrow_flight.a` is missing symbols from `libarrow.a` and the bundled gRPC is missing symbols from OpenSSL. This works: ``` /usr/bin/c++ -O3 -DNDEBUG CMakeFiles/arrow_example.dir/example.cc.o -o arrow_example /home/lidavidm/Code/upstream/arrow-14708/install/lib/libarrow_flight.a /home/lidavidm/Code/upstream/arrow-14708/install/lib/libarrow.a -pthread /home/lidavidm/Code/upstream/arrow-14708/install/lib/libarrow_bundled_dependencies.a /usr/lib/x86_64-linux-gnu/libssl.so /usr/lib/x86_64-linux-gnu/libcrypto.so -lrt ``` i.e. link libarrow_flight, then libarrow, then libarrow_bundled_dependencies, then OpenSSL. Flipping the order of libraries in the CMakeLists.txt fixes the first issue, so I suppose this is user error, or we're missing some dependency expressed in CMake(?). The installed ArrowFlightTargets.cmake does *not* declare arrow_static in INTERFACE_LINK_LIBRARIES - my CMake understanding is poor but perhaps we need to do so? (It is odd because arrow_static is in the STATIC_LINK_LIBS in flight/CMakeLists.txt.) Also, ArrowTargets.cmake declares OpenSSL as part of arrow_static's INTERFACE_LINK_LIBRARIES, but ArrowConfig.cmake does not do the same for arrow_bundled_dependencies. -- This is an automated message from the Apache Git Service.
