带有或不带有MSYS的MinGW Makefile(del vs rm) [英] MinGW makefile with or without MSYS (del vs rm)

问题描述

我正在使用MinGW在Windows上编译一些东西.我直接从cmd.exe调用mingw32-make，一切(我需要)都可以正常工作.但是我发现我将需要能够在MSYS环境中进行编译，并且我遇到了copy和del命令无法识别的问题.我知道只用cp和rm替换它们，但是我想在两种情况下都使用单个makefile.

I am using MinGW for compiling some stuff on Windows. I call mingw32-make directly from cmd.exe and everything (I need) works fine. However I found out I will need to be able to compile from the MSYS environment and I run in problems with copy and del commands not beeing recognized. I know it is only matter of replacing them with cp and rm, but I would like to use single makefile for both cases.

是否有一种方法可以强制msys环境调用系统del和cp命令?

Is there a way to force msys environment to call system del and cp commands?

或者更好的是，有没有办法区分是从cmd.exe还是msys调用makefile?比我可以为命令设置适当的变量.这将非常有帮助，因为这样我就可以删除其他一些重复的makefile.

Or better yet, is there a way to distinguish whether the makefile is called from cmd.exe or msys? Than I could set appropriate variables for the commands. This would be quite helpfull, because I could then remove some other duplicate makefiles.

感谢您的帮助.

谢谢

而且要使事情更困难:如果从cmd.exe运行时在PATH中找到mingw32-make，则似乎正在使用sh.exe.这具有完全不同的环境变量集.

And to make things more difficult: mingw32-make seems to be using sh.exe if found in PATH when run from cmd.exe. This has completely different set of environment variables.

编辑:好吧，如果仍然有人感兴趣，我最终得到了以下文件，该文件包含在我的其他Makefile中:

OK, if anyone is still interested, I ended up with the following file, which I include to my other Makefiles:

ifeq ($(OS),Windows_NT) 
RM = del /Q /F
CP = copy /Y
ifdef ComSpec
SHELL := $(ComSpec)
endif
ifdef COMSPEC
SHELL := $(COMSPEC)
endif
else
RM = rm -rf
CP = cp -f
endif

如果不是，您仍然认为这是一个重复的问题，我当然可以删除此问题.

If not, and you still think this is a duplicate question I can of course delete this question.

出于我未知的原因，ComSpec和COMPSPEC有所作为.

For reasons unknown to me ComSpec and COMPSPEC make a difference.

推荐答案

我和您遇到了同样的情况.我将MSYS目录添加到virtual环境中，并且运行良好.

I met the same condition with you. I add MSYS directory to PATH environment virable, and it works well.
