makefile - mingw32-make 的目录更改错误

Question

我正在MinGW32下构建POCO库1.6.0，环境:Windows 7 Ultimate 32位，shell:MSYS。成功执行./configure。

$ ./configure
Configured for MinGW

config.make的内容:

POCO_CONFIG = MinGW
POCO_BASE = /c/dev/poco
POCO_BUILD = /c/dev/poco
POCO_PREFIX = /usr/local
POCO_FLAGS = 
OMIT = 
export POCO_CONFIG
export POCO_BASE
export POCO_BUILD
export POCO_PREFIX
export POCO_FLAGS

启动 mingw32-make 后我得到:

$ mingw32-make --debug -w

问题出在

mingw32-make: Entering an unknown directory
mingw32-make: *** /c/dev/poco/Foundation: No such file or directory.  Stop.

因为/c/dev/poco/Foundation确实存在:

$ ls

JSON            Util      build_vs100.cmd          config.build

我正在修改makefile以将目录更改为其他子文件夹，没有乐趣。似乎有什么东西阻止 mingw32-make 更改目录。也可以确认

cd /c/dev/poco/Foundation

工作正常。

尝试使用make，结果是相同的:

由于路径没有空格，mingw32-make 没有明显的原因失败。

我错过了什么？欢迎任何建议。

在 mingw32-make.exe 的上下文中，路径 /c/dev/poco/Foundation 并不意味着您所想的那样。看，mingw32-make.exe 是一个 native Windows 应用程序，因此它肯定不会理解 >MSYS具体路径如/c/dev/poco/Foundation；相反，它将“按原样”解释为 c:/c/dev/poco/Foundation(假设您当前的工作驱动器是 c:)，我我确信这不是您想要的。

您似乎确实使用 MSYS 作为 shell，那么为什么还要使用 mingw32-make.exe 呢？使用MSYS本身提供的make.exe；它确实理解 MSYS 路径。

请注意，如果您从 MSYS shell 运行 make --version，您应该看到(在撰写本文时):

$ make --version

在您更新的问题中，您展示了一个运行 make.exe 的示例，这显然不是这个 MSYS 版本；看来您已经放置了make.exe的替代版本——甚至可能是mingw32-make.exe本身的副本，用于输出是相同的——在 $PATH 中 MSYS 版本之前的某个目录中。您应该删除这个非 MSYS 版本的 make.exe；调用 MinGW 版本 mingw32-make.exe 的全部目的就是为了避免这种冲突。当您从 MSYS shell 运行 make 时，您需要 MSYS 版本，而不是某些 mingw32-make.exe 克隆。
