Thanks Roman ! /usr/bin/c++ points (now) to /usr/bin/g++. It works after a reset of the build folder.
I have found that the origin of the issue is Anaconda, a package and virtual environnement manager for scientific Python packages. I have installed a differential equations solver shipped with its own tweaked GCC/G++ compiler within a conda environnement, and as Anaconda exports the path of its internal binaries in .bashrc, it supercedes the system binaries with its own. Thus, calling the build.sh script, bash used G++ from the Anaconda environnement. *Aurélien PIERRE* aurelienpierre.com <http://aurelienpierre.com> ------------------------------------------------------------------------ Le 2017-05-16 à 14:15, Roman Lebedev a écrit : > On Tue, May 16, 2017 at 9:08 PM, Aurélien PIERRE > <rese...@aurelienpierre.com> wrote: >> Hi, >> >> I'm trying to compile DT 2.2.4 from the sources on Ubuntu 16.04.
