Might be a cache issue ?

Should be fixed now, I hope.

2.0.0-21:
should fix compilation with FLTK 1.4. Other changes related to Julia interoperability.

Indeed, the library file is missing, this will be fixed for the next binary packages, thanks for pointing. By the way, if it happens that some library files are missing, the easiest way to add them is to install them from an install with brew.

The reason might be that mkjs is supposed to be a native binary of the host, it should not be cross-compiled as a target binary, because the target binary will not be executable on the host if cross-compiled. I don't know how to tell that in Makefile.am, therefore I will remove the mkjs dependancy o...

I'll check later for changes for fltk 1.4, before that's done I propose as a workaround to modify configure.ac: dnl Run autoreconf -iv to produce the configure script and associated files. dnl Giac version number m4_define([giac_major_version], [2]) m4_define([giac_minor_version], [0]) m4_define([gi...

Probably some incompatible change with FLTK. Which version of FLTK are you using ? Is it 1.4.x?
Is it possible to compile with FLTK 1.3.x, or disable the system fltk so that giac compiles against its own static version of FLTK 1.3 ?

2.0.0-19
Adds autoscale support for plotfunc call inside plotseq

Cours du 20 novembre (11 sur 13) Comportement des solutions d'équations autonomes y'=f(y): équilibre si f(r)=0, y=r, stable si f passe de positif à négatif en y=r, instable dans le cas contraire. Si f'(r)<0 stable, si f'(r)>0 instable. Exemple y'=y0^4-y^4 (cf. l'exam de janvier 2023) Le linéarisé de...
