Description

I am trying to build the onnxruntime package:

conan create . onnxruntime/1.15.1 --build=missing -o onnxruntime:shared=True -o date:header_only=True -ks -kb

This is all that its recipe does with flatbuffers:

self.requires("flatbuffers/1.12.0")
...
if self.dependencies["flatbuffers"].options.shared:
    deps.set_property("flatbuffers", "cmake_target_name", "flatbuffers::flatbuffers")

While trying to compile flatbuffers for my settings, I get this error:

flatbuffers/1.12.0: CMake command: cmake --build "/home/artalus/tmp/conan-center-index/recipes/onnxruntime/all/.conan/data/flatbuffers/1.12.0/_/_/build/ca2dd21bf3fe05774d1f7645d2552468636d038f/build/Release" '--' '-j8'

There are two issues here:

  • flatbuffers assumes abseil is present in the system when it can't find it in the stdlib. This is fine for direct users but Conan needs reproducibility - When no cppstd is defined, we'll force flatbuffers not to use string_view, which will solve the issue of abseil
  • flatbuffers is unconditionally setting CMAKE_CXX_STANDARD to 11 if no cppstd is defined in the Conan profile - This is bad for Conan 1, which does not model it by default, and so compilers that would by default work, won't. I'm still looking for the proper way to fix this (Probably just removing that condition).

I've talked with the team again about this, and we're going to check with upstream what their reasonale for this is, and if there's a chance that this behaviour can be configured/disabled as needed to avoid situations like these, thanks a lot for your patience @Artalus
