Compilation GCC : undefined reference to ...

Bonjour,

Je vous solicite concernant un problème que je rencontre depuis maintenant 3 semaines.

Je souhaite compiler pluiseurs fichiers à l'aide de gcc, mais lorsque que j'execute la commande make, je tombe sur quelques erreur qui empêche la compilation.

Voici mes erreurs :

make[1]: entrant dans le répertoire « /home/johann/Interferometry/nsbas_tmp/src/dinsar »
