[Mingw-users] weird path conversion with 'make'

[Nathan R. <zer...@ho...>]

Hello,

I'm trying to use MinGW make to compile a program with the Visual C++ compiler, but
I'm running into some strange behaviour.

Consider the following trivial makefile:

my_program :
        cl /c src\test.cpp

("cl" is the command for the Visual C++ compiler).

This works fine. However, if I add quotes around the input file name, as such:

my_program :

        cl /c "src\test.cpp"

I get an error:

cl : Command line warning D9024 : unrecognized source file type 'c:/', object file assumed

It seems that MinGW make is converting the /c option into the path c:/
However this seems to only happen if there are quotes around the src\test.cpp
If there are no quotes, everything is fine.

If I add other options, it gets even weirder:

my_program :


        cl /c /O2 "src\test.cpp"

cl : Command line warning D9024 : unrecognized source file type 'c:/', object file assumed
cl : Command line warning D9024 : unrecognized source file type 'C:/mingw/msys/1.0/O2', object file assumed

Again, MinGW make converted something that wasn't supposed to be a path, into a path.
But again, it works fine if I removed the quotes around src\test.cpp

What is going on here? Can this path conversion functionality be disabled?

Note that while I have MSYS installed on my system, I am using a regular Windows command
prompt, not MSYS, and I am using mingw32-make, not MSYS make.

Thanks,
Nate.
