thx :)

For FLP Suite v0.18.x releases we do have a dedicated branch so this applies from v0.19.0

@ktf Could you remove devtoolset section from https://alice-doc.github.io/alice-analysis-tutorial/building/prereq-centos7.html ?

[ktf]

@awegrzyn done in alice-doc/alice-analysis-tutorial#130. We should probably revisit those instructions completely.

@Barthelemy @awegrzyn : o2/alidist-dataflow is green, can I merge it?

[Barthelemy]

That went a lot smoother than I expected !

On my setup I get No package 'capstone' found and then parallel_backend_tbb.h:28:6: error: #error Intel(R) Threading Building Blocks 2018 is required, any ideas?

[davidrohr]

For the TBB thing, without knowing fully for sure: GCC uses TBB if avaiable for its std::parallel stuff. That is decided at compile time. So when you compile GCC on a system with TBB headers available, and then copy it to a system without TBB headers, one might get the error you see. Though not 100% sure if it is that, but since you mention parallel_backend_tbb.h, I'd say I am 99% sure :)
No idea for capstone.

Sorry, forgot to mention that this happens when compiling DebugGUI

[davidrohr]

Ah, ok, so then the problem might be: You probably have a TBB installed, but an older version than what is required by GCC. DebugGUI contains tracy, which has some logic to detect tbb. It probably finds the old version and tries to use it, and then GCC fails to compile with it.
Ping @ktf

Yes, I am trying to update Tracy to see if that fixes the problem/
