RE: Does arrow/cpp setup google flatbuffers lib by itself?

I don't have $FLATBUFFERS_HOME and I'd rather depend on the setup_build_env.sh work. setup_build_env.sh does work and leave this folder thirdparty/flatbuffers-1.3.0 that looks good. The root cause that it doesn't work fully looks like to be Flatbuffers_HOME isn't set in CMakeLists.txt file.

Re: Does arrow/cpp setup google flatbuffers lib by itself?

There could be a cmake caching issue, too. So trying a fresh clone (or deleting your out-of-source build directory) may help. Be sure to check $FLATBUFFERS_HOME and look in that directory to check for `flatbuffers/flatbuffers.h` On Sun, Mar 27, 2016 at 6:55 PM, Zheng, Kai

Re: Does arrow/cpp setup google flatbuffers lib by itself?

Hi Kai, This might not solve your problem but I had an issue building flatbuffers. The fix was I had to modify the flatbuffers cmake file (thirdparty/flatbuffers-1.3.0/CMakeLists.txt) to force -std=c++11 instead of c++0x. I also don't think build_thirdparty.sh is properly surfacing errors if the

RE: Does arrow/cpp setup google flatbuffers lib by itself?

Hi Wes, Yes I did `sh setup_build_env.sh`. Everything else works fine, except the flatbuffers lib. If it assumes equipping the lib by itself, I can look into the issue and see if a fix is needed or not. Thanks. Regards, Kai -Original Message- From: Wes McKinney

Re: Does arrow/cpp setup google flatbuffers lib by itself?

hi Kai, Did you run source setup_build_env.sh ? You can also manually run the thirdparty build scripts, but then you must set the environment variables yourself (see the setup_build_env.sh and also the Travis CI scripts for a complete accounting). Thanks Wes On Sun, Mar 27, 2016 at 5:25 PM,
