makefile 删除 uname 命令

Question

我只想在 windows cmd 中运行 make。目标只是我可以在默认情况下运行 make windows CMD 而不需要在 MSYSY 或 CYGWIN 中运行 make。

当我在 windows cmd 中运行 make 命令时，它显示消息：'uname' 未被识别为内部或外部命令、可运行程序或批处理文件。 process_begin: CreateProcess(NULL, uname -m, ...) 失败。

Answer 1

看这里：

UNAME      := $(shell uname | tr '[:upper:]' '[:lower:]')

你运行$(shell uname...) 。 这将启动 shell 并运行给定的命令。 如果你运行 make 以便它使用cmd.exe作为它的 shell 而没有 msys 或 Cygwin，那么就好像你输入了uname | tr '[:upper:]' '[:lower:]' uname | tr '[:upper:]' '[:lower:]'在您的cmd.exe提示符处，如您所见，这显然会失败。

如果您想避免使用 msys 或 Cygwin，那么您必须修复所有makefile 以不使用任何 POSIX 命令，包括此处。
