通用Makefile模式将每个源编译为相应的目标文件

时间：2015-04-16 08:35:41

标签： c gcc makefile rule

您好我正在尝试使用通用makefile来构建我的项目。

我得到的错误是我的源代码中存在重复的函数。我检查了nm，是的，他们在那里。我知道我可以用每个明确命名的源文件编写一个normale makefile，并逐行编译。但是我的项目的性质要求，其他人能够在没有新平台的情况下整合新平台，并将整个事件移植到新机器上。 （这意味着从长远来看，即使是直接的库路径也必须变得相对） 任何帮助表示赞赏。

其他信息： 主机系统是Windows 7，我使用MinGW 32（nuwens发行版）进行编译 - 作为交叉编译器和库提供程序，我使用ARM-Launchpad中的gnu-arm-none-eabi-gcc。

更新： 我在VPATH中添加了一些缺失的包含，现在至少它编译为开头所述的错误：

更新了错误示例：

TimeTillAlarm只存在一次。其他地方没有预先声明。在整个来源上为它做好准备。

更新 nm表示所有汇编器o.files具有相同的符号

来自c_sources的o.files看起来形状相同，但至少有一组不同的符号。 结论：一个源文件被制作成两个组的名为o.files的不同文件。有人建议为什么？

再次感谢您的耐心和建议
