devkitPro

I have been trying to compile DSI games as usual by opeing up the folder and using PowerShell and typing Make and I am getting this error. I have had this for weeks now and it started right after a windows update. I have tried to update Cygwin and DevkitPro but with no luck. If anyone can help please do.

ERROR:
0 [main] mkdir (14324) C:\devkitPro\tools\bin\mkdir.exe: *** fatal error - cygheap base mismatch detected - 0x180345408/0x180347408.
This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version. The most recent version *should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution. Rebooting is also suggested if you
are unable to find another cygwin DLL.
make: *** [Makefile:94: build] Error 127

We don't support use with cygwin. We provide *nix tools with msys2 which you should be able to find under the devkitPro start menu.

It looks like you've tried to copy cygwin binaries into the devkitPro tools folder where they have no business being. I'd recommending purging cygwin from your machine, uninstalling your devkitPro toolchains & then reinstalling without ever putting cygwin anywhere near your machine again.
