Makefile中的错误：gcc：error：filename.o：没有找到这样的文件或目录

Question

我有以下的makefile，但是当我将它编译为时出现错误：找不到这样的文件或目录。 这是我正在执行的makefile： P.S.我正试图在Linux和Windows上执行此操作，但两者都出现同样的错误。

make: *** [coder] Error 1 

Answer 1

编译器不找对象文件，因为它们不建。并且目标文件不会生成，因为源文件位于不同的目录中（例如src），或者由于某些其他原因make不会看到它们。

我调查了这多一点与--debug

make --debug=v -f makefile.gcc 

，并得到

gcc: error: autocorr.o: No such file or directory

因为头文件的依赖性，使得公司认为他们已经正确地重拍的对象文件的目标，甚至尽管它没有看到源文件。

如果提供的源文件（即使是空的），输出看起来不同的一点

...
Finished prerequisites of target file `coder.o'.
Must remake target `coder.o'.
gcc -Wall -g -O4 -DWMOPS=0 -D__MSDOS__ -c coder.c

在这里你可以看到，如何让检查所有先决条件，然后重建对象文件，使用在makefile中给出的隐式规则。

您可以通过将源文件明确列为依赖项来避免混淆，例如，然后

coder.o: coder.c 

make会抱怨缺少的源文件，而无需调用链接命令

make: *** No rule to make target `coder.c', needed by `coder.o'. Stop.
