[SOLVED] Flexible plugin fails to compile in v17.12

[Noura]

Hello,

I noticed that Flexible plugin doesn’t compile anymore in v17.12.

Here is my configuration:
Sofa v17.12
Ubuntu 18.04
cmake version 3.10.3

and the compilation error:

Scanning dependencies of target Flexible

I’m Wondering if anyone had the same issue?

Hi Noura,

Strange that this error is not detected..
The correct typo is SearchUp and not searchUp. Can you give it a try ?

Best,

Hi Hugo,

I think that searchUp should be called here, as it a BaseObject function.

typename T::SPtr searchUp() const { const BaseContext* context = getContext(); return typename T::SPtr(context->get<T>(BaseContext::SearchUp)); }

I also noticed that this error is gcc dependent:
– using gcc 7.3.0 => compilation error
– using gcc 5.4.0 => compiles fine

Best,

Noura

Just to conclude before closing the thread: it looks like gcc 7.3.0 issue. I switched to clang 6.0.0 without any problems.

Thanks a lot for the notice Noura
