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，不高兴。似乎有些东西阻止了 mingw32-make 更改目录。也可以确认

cd /c/dev/poco/Foundation

工作正常。

用make试过，结果是一样的：

没有明显的原因导致 mingw32-make 失败，因为路径没有空格。

我错过了什么？欢迎提出任何建议。

在mingw32-make.exe 的上下文中，路径/c/dev/poco/Foundation 并不代表您的想法。看，mingw32-make.exe 是一个本机 Windows 应用程序，所以它肯定将不理解MSYS 特定路径，例如/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:），我确定这不是您想要的。

您似乎确实使用MSYS 作为您的外壳，那么您为什么还要使用mingw32-make.exe？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；似乎你已经放置了make.exe的替代版本——甚至可能是mingw32-make.exe本身的副本，因为输出是相同的——在你的@中MSYS版本之前的某个目录中987654338@。你应该删除这个非 MSYS 版本的make.exe；调用 MinGW 版本mingw32-make.exe 的全部目的是避免这种冲突。当您从 MSYS shell 运行 make 时，您需要 MSYS 版本，并且不是一些 mingw32-make.exe 克隆。
