調査の方向性

src/cmdstan/main.oをビルドするmakeルールから始め、モデルの変換に失敗した後にそれが再度実行される理由を追跡します。失敗するStanモデルに続けて修正済みのモデルを使い、make ~/temp2/absでその一連の流れを再現します。main.cppとその依存関係が変更されていない場合に、後続のmakeがmain.oを再利用し、変更された場合には再ビルドすれば完了です。

索引モデルが issue の本文から書いたものです。

説明

bug makefile

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?

It just happens again. And remember "This might take up to a minute."

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

It still recompiles main.cpp.
