Hello, I am sorry, but I think that I solved the issue by running a make clean Now the generated code is the same on both machines. Probably I have an object from a previous version of gsl which was not recompiled at the same time on both machines. My Makefile is probably not optimum. How can I force a compilation in case of an update of a library like gsl? Thank to every body for the help. > Sent: Thursday, November 14, 2024 at 9:56 AM > From: "Jakub Jelinek" <jakub@xxxxxxxxxx> > To: "Patrick Dupre" <pdupre@xxxxxxx> > Cc: "Community support for Fedora users" <users@xxxxxxxxxxxxxxxxxxxxxxx>, "Barry" <barry@xxxxxxxxxxxxxxxx> > Subject: Re: gcc/gsl > > On Thu, Nov 14, 2024 at 09:25:40AM +0100, Patrick Dupre wrote: > > No, I do not use such options > > Then I don't believe you can get different assembly from the same compiler > same source same options.
