标签： c++ makefile g++ embedded-linux stm32f4discovery

我正在为stm32f4微编译器构建一个makefile，它包含所有外围库，并包含一个syscalls（名称newlib_stubs.cpp），其中printf（）重定向到uart。在我开始将所有源代码构建到自己的目标文件以链接到可执行文件之前，我编写了makefile，以便在一次命中中编译所有源代码以证明makefile在此阶段工作但它不起作用。 这是makefile：

我无法识别main.cpp文件中的任何错误，而这些错误似乎来自于它们。

这个错误的包装是什么以及如何修复？

1 个答案:

答案 0 :(得分：6)

您的Makefile设置LDFLAGS+=-T $(LDSCRIPT)但未定义$ LDSCRIPT。这导致调用g++ -T {nothing here} main.cpp ...，因此链接器假定main.cpp是脚本。尝试从Makefile中删除LDFLAGS+=-T $(LDSCRIPT)。
