Please find attached a patch that removes -std=c+11 from the compiler flags. It fixes the FTBFS, and at first glance there does not seem to be any negative side effect. -- ⢀⣴⠾⠻⢶⣦⠀ Sébastien Villemot ⣾⠁⢠⠒⠀⣿⡁ Debian Developer ⢿⡄⠘⠷⠚⠋⠀ https://sebastien.villemot.name ⠈⠳⣄⠀⠀⠀⠀ https://www.debian.org
Description: Fix FTBFS against Octave 10 Octave 10 headers use the C++17 standard, while the NLopt build system enforces the C++11 standard. This patch removes -std=c++11 from the compiler flags, to allow C++17 headers.
