具有 2 个源目录的 makefile make include guard 失败
makefile with 2 source directories make include guard fail
我有一个项目，源代码位于 2 个位置。
当项目链接时，它抱怨一个函数是双重定义的（它不是）：

我认为这是因为 makefile 对每个目录有 2 个不同的编译方法，并且它们不共享预编译定义。
有没有更好的方法来制作一个包含 2 个源目录的项目？我应该只将不同目录中的几个源添加到一个迷你库然后添加吗？

人们总是从多个目录构建项目。每个案例都需要不同的方法。
您发布的内容应该有效。由于 Makefile，多重定义很可能 而不是 。我会更仔细地查看错误。 toolchain 告诉您它在哪里找到这两个定义。
