Makefile组合规则未执行定义的其他规则

执行make会失败，因为它无法在make文件中找到先前定义的规则。另外，如果我用“做目录”中的“目录”的规则只适用，但是当我把它添加到由规则也列出文件在工作目录....Makefile组合规则未执行定义的其他规则

你没有一个组合的规则，你有'test_tester'目标没有先决条件，只是一长串命令。 https://www.gnu.org/software/make/manual/make.html#Rule-Introduction – melpomene

@melpomene规则的先决条件是否必须具有构建目录前缀？ –

@eat_a_lemon先决条件与目标相同，所以你的意思是'test_tester：dir'？与dir-target相反，mkdir必须缩进到下一行 – Ctx

我想通了感谢。
