问题
I'm building POCO library 1.6.0 under MinGW32, environment: Windows 7 Ultimate 32-bit, shell: MSYS. Successfully executed ./configure.
$ ./configure
Configured for MinGW
Contents of config.make:
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
After launching mingw32-make I'm getting:
$ mingw32-make --debug -w

The problem is in
mingw32-make: Entering an unknown directory
mingw32-make: *** /c/dev/poco/Foundation: No such file or directory. Stop.
because /c/dev/poco/Foundation does exist:
$ ls

I was modifying makefile to change directory to other sub-folders, no joy. It seems like something prevents mingw32-make from changing directory. Also can confirm that
cd /c/dev/poco/Foundation
works fine.
Tried with make, result is the same:
$ make --debug -w

There are no obvious reasons for mingw32-make to fail as path does not have spaces.
What I have missed? Any suggestions welcome.
回答1:
The path /c/dev/poco/Foundation does not mean what you seem to think, in the context of mingw32-make.exe. See, mingw32-make.exe is a native Windows application, so it definitely will not understand an MSYS specific path such as /c/dev/poco/Foundation; rather, it will interpret it "as is", as c:/c/dev/poco/Foundation, (assuming your current working drive is c:), which I'm sure is not what you intended.
You do seem to be using MSYS as your shell, so why are you using mingw32-make.exe anyway? Use the make.exe that MSYS itself provides; it does understand MSYS paths.
Do note that, if you run make --version from the MSYS shell, you should see, (at this time of writing):
$ make --version

In your updated question, you show an example of running make.exe, which clearly is not this MSYS version; it appears that you have placed an alternative version of make.exe -- perhaps even a copy of mingw32-make.exe itself, for the output is identical -- in some directory which precedes the MSYS version in your $PATH. You should delete this non-MSYS version of make.exe; the entire purpose in calling the MinGW version mingw32-make.exe is to avoid this very conflict. When you run make from the MSYS shell, you want the MSYS version, and not some mingw32-make.exe clone.
