undefined reference to `Halide::Internal::Introspection::

[shipingli]

I am trying to build HelloeHexagon on Linux Halide 2.0, stuck on below error. No idea on how to proceed, any help?

Thanks

Looks like a C++ abi mismatch issue. What g++ version are you using, and how did you acquire or compile Halide?

I got Halide 2.0 from https://developer.qualcomm.com/software/hexagon-dsp-sdk/tools, and I am using gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4)

What version is required?

Thanks

Ah, then it depends on how the qualcomm folks compiled their libHalide. I'm guessing they used an older compiler. I would just checkout and compile Halide from source.

Seems to me some libraries or headers not properly included in Halide 2.0. Are we going to migrate everything to 2.0? What if I just want to run apps using ARM/Neon inside Qualcomm chip?

[abadams]

I'll ping one of the qualcomm people @ronlieb

Thanks, I also tried to communicate with them yesterday. They asked g++ version too.

[ronlieb]

We think they need to use g++ 4.8.4 , that is what our Halide 2.0 release is built with , and built on ubuntu 14.04

This is the dual-ABI thing again. TLDR: compile your code with -D _GLIBCXX_USE_CXX11_ABI=0

https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html

[shipingli]

I am using HALIDE_Tools/2.1 now, any idea what g++ version I should use? or is there a solution that does not require the end user using old g++?

Thanks

Sorry, did not read it clearly, using -D _GLIBCXX_USE_CXX11_ABI=0 fixed issue
