Do you know how to fix this issue?

Step to reproduce: clone from my mingw64 branch on https://github.com/iahunq/COS/tree/mingw64 and try to build with make on MINGW64. It will fail with this error:

MINGW64/release/Any.d:1: *** multiple target patterns.  Stop.
make: *** [CosBase/include/cos/mak/common:44: CosBase] Error 2

Strangely enough it will not fail on the MSYS environment.

I got the following error.

$ make
CosBase/include/cos/prologue:119: CosBase/include/cos/cfg/MINGW64: No such file or directory
make: *** No rule to make target 'CosBase/include/cos/cfg/MINGW64'.  Stop.

You have to clone from the mingw64 branch: https://github.com/iahunq/COS/tree/mingw64

git clone -b mingw64 https://github.com/iahunq/COS

My apology, I have no idea why it failed. But the issue does not seem related to msys2 or mingw64.

@Biswa96 Open COS/CosBase/MINGW64/release/Any.d you will see the paths all begin with /msys64/mingw64/. I tried to run the command cd /msys64 and it failed with -bash: cd: /msys64: No such file or directory. So it seems the paths are invalid. /msys64 should be replaced with /. The rule to generate .d files is on COS/CosBase/include/cos/mak/compile. I have no idea why it generated invalid paths on MINGW64. It works as expected on MSYS.

Update: I know how to fix this problem. The sed command on COS/CosBase/include/cos/mak/compile needs the -z switch to work as expected on MINGW64.
