Build failed about fptuner

[huanghx1990]

The issue relates to the version of FPTaylor being used. This used to be solvable by lowering the version of ocamlc in opam.

Modern versions of ocamlc provided by opam can no longer compile the version of FPTaylor used. Updating the FPTaylor version would require rewriting the interface between FPTuner and FPTaylor.

Hi, Ian, could you give the detail version of ocamlc for the fptuner installation? Thanks very much

Hi,
I am trying to build and use FPTuner in an Ubuntu 16.04 x86_64 machine. I installed the latest Gurobi, but the FPTuner build fails in InstallFPTaylor. What should I do to fix this?

Thank you very much.

I also have this error, did you fix it？if you do, could you share your solution?

Thanks for reporting this! Unfortunately, students who implemented FPTuner graduated a few years ago, and currently there is nobody maintaining FPTuner. So I am not sure how we would be able to help. Sorry!
