我有下面的Makefile,由于某种原因它依赖于文件ewapi.c。此文件执行一些SWIG命令并使用ewapi.i文件。我清除了ewapi.c的所有内容,并且Makefile成功运行。如果我删除ewapi.c文件,make文件将无法完成。如果有帮助,异常堆栈在下面。关于如何更改Makefile以使其不依赖于ewapi.c的任何想法?

答案 0 :(得分:1)
宏OBJECTS
包括$(OBJ_DIR)/ewapi.o
; $(TARGET)
的规则说明取决于$(OBJECTS)
; all
的规则说明取决于$(TARGET)
。因此,需要有一种方法可以从某些内容创建ewapi.o
- 如果没有ewapi.c
,则无法构建ewapi.o
,因此您会得到投诉。
可能的修复:
ewapi.c
。ewapi.o
移除$(OBJECTS)
。答案 1 :(得分:1)
从$(OBJ_DIR)/ewapi.o
删除OBJECTS
。
