Question

也许这是一个非常明显的答案，但我正在尝试在Windows环境中使用C扩展Ruby而且当我运行mingw32时我无法进行扩展 - 使得它生成一个名为“forktest”的文件-i386-mingw32.def“然后说”没有规则来制作目标'ruby.h'，'forktest.o'需要。“

Forktest是我正在尝试制作的扩展名。

makefile是由ruby自己的create_makefile命令生成的，它确实令人费解，所以我无法理解它，但无论如何它都在这里：

SHELL = /bin/sh

# V=0 quiet, V=1 verbose.  other values don't work.
V = 0
Q1 = $(V:1=)
Q = $(Q1:0=@)
n=$(NULLCMD)
ECHO1 = $(V:1=@$n)
ECHO = $(ECHO1:0=@echo)

我遇到了同样的问题，发现我不小心在我的路上做了 MinGW 制作。这意味着Ruby DevKit在它自己的 msys 版本之前发现了该版本。

mingw版本不处理/D/Programs/Ruby193/样式的路径，并产生“没有规则来制作目标'ruby.h'......”错误。

我的解决方法是从我的PATH中删除MinGW make，以便Ruby DevKit在运行时找到msys版本的Make（当它打印“暂时增强PATH以包含DevKit ...”时）。

我从msys.bat环境检查了我的Make版本（只运行C：\ devkit \ msys.bat）：

$ which make
# Should print a location like: C:\devkit\bin\make.exe

并检查这样的版本：

$ make --version

正确的 msys 版本包含在最后一行：

此程序专为i686-pc-msys
而构建

错误的 MinGW 版本输出：

GNU Make 4.1 专为i686-w64-mingw32而设计

我正在使用 ruby 2.2.3p173 和 DevKit-mingw64-32-4.7.2-20130224-1151-sfx ，但这似乎是一个路径问题，不是红宝石问题。

Ruby生成的makefile不运行
