Thanks Wes, Yea, we might be trying to play with the code a bit too early.
I made a little more progress, but became stuck during make. I might be at the same place as kszucs: https://github.com/apache/arrow/pull/2547#issuecomment-425744800 This could be completely incorrect, but I made it past cmake by hard-coding environment variables (such as GPR_STATIC_LIB) in ThirdPartyToolChain.cmake because LOCATION wasn't defined. - get_property(GPR_STATIC_LIB TARGET gRPC::gpr PROPERTY LOCATION) + set(GPR_STATIC_LIB "/usr/local/lib/libgpr.a") However, now I fail on protobuf dependency: [ 95%] Built target arrow-stream-to-file make -f src/arrow/flight/CMakeFiles/arrow_flight_objlib.dir/build.make src/arrow/flight/CMakeFiles/arrow_flight_objlib.dir/depend make[2]: Entering directory '/home/t.bisson/git/arrow/cpp/debug' make[2]: *** No rule to make target '../src/arrow/flight/protobuf', needed by 'src/arrow/flight/Flight.pb.cc'. Stop. make[2]: Leaving directory '/home/t.bisson/git/arrow/cpp/debug' CMakeFiles/Makefile2:1450: recipe for target 'src/arrow/flight/CMakeFiles/arrow_flight_objlib.dir/all' failed make[1]: *** [src/arrow/flight/CMakeFiles/arrow_flight_objlib.dir/all] Error 2 make[1]: Leaving directory '/home/t.bisson/git/arrow/cpp/debug' Makefile:143: recipe for target 'all' failed Google indirectly suggests header/c code generation might not be working. However, I was able to generate the the files manually into their correct directories. Any additional suggestions are appreciated.
