recompiling main.cpp each time

Commencez par la règle make qui construit src/cmdstan/main.o et cherchez pourquoi elle s’exécute à nouveau après l’échec de la traduction du modèle. Reproduisez la séquence avec make ~/temp2/abs, en incluant un modèle Stan qui échoue, suivi d’un modèle corrigé. C’est terminé lorsqu’un make ultérieur réutilise main.o si main.cpp et ses dépendances sont inchangés, et le reconstruit lorsqu’ils changent.

Summary:

When I run the latest develop version of cmdstan, it recompiles the main.cpp every time, but it should only have to be compiled once.

Description:

The main.cpp should only be compiled once, then re-used.

So this fails to compile the model, but what happens to the make.cpp compilation?

OK, this time it succeeded. Now let me change my program for abs and see what happens.

It still recompiles main.cpp.
