recompiling main.cpp each time

Bắt đầu với quy tắc make xây dựng src/cmdstan/main.o và truy tìm lý do nó chạy lại sau khi việc dịch mô hình thất bại. Tái hiện chuỗi này bằng make ~/temp2/abs, bao gồm một mô hình Stan bị lỗi, sau đó là một mô hình đã được sửa. Được xem là hoàn tất khi một lần make sau đó sử dụng lại main.o nếu main.cpp và các phần phụ thuộc của nó không thay đổi, đồng thời xây dựng lại nó khi chúng thay đổi.

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.
