I tried to upgrade cmdstan from 2.30.0 to 2.30.1 by unpacking [this zip file](https://github.com/stan-dev/cmdstan/archive/refs/tags/v2.30.1.zip) zipfile to C:\cmdstan-2.30.1 and then following the instructions [here](https://mc-stan.org/docs/2_30/cmdstan-guide-2_30.pdf).

The first problem is that Command Prompt doesn’t recognize `mingw32-make` as a runnable command. The troubleshooting says to address this by calling:

`pacman -Sy mingw-w64-x86_64-make`

But this command runs into the following errors:

```nohighlight

```

Is there a path forward from this?

No idea, but perhaps try: `gpg --refresh-keys`

Tried that, same thing happens though.

Strange… This seems to be the problem:

Yes sir, that’s a very mystifying message. Bad grammar and all.

Well, I seem now to have graduated to the next problem. Since the first problem was just the failure of the system to recognize mingw32-make as a command, what seems to have worked is that I simply went to my RTools42 directory, located mingw32-make.exe, and added its location to the PATH environment variable from Control Panel → System → Advanced System Settings → Environment variables.

After doing this, I am able to run mingw32-make. So, the next step is to use mingw32-make to build cmdstan. This I try to do by opening Command Prompt, going to the C:\cmdstan-2.30.1 directory, and calling `mingw32-make build`. The resulting output is so voluminous that the scrollback fails to capture all, but the end of it looks like this:

Any idea what the problem is?

Three follow-up questions as well:

1. Does it matter whether the file I’ve downloaded and unpacked is [cmdstan-2.30.1.tar.gz](https://github.com/stan-dev/cmdstan/releases/download/v2.30.1/cmdstan-2.30.1.tar.gz) or [Source code (zip)](https://github.com/stan-dev/cmdstan/archive/refs/tags/v2.30.1.zip)?
2. Does it matter whether I have unpacked one of the two aforementioned files manually or “automatically”, i.e. by opening a Git Shell and calling `git clone https://github.com/stan-dev/cmdstan.git --recursive`?
3. When I tried the Git Shell approach, the automatic installation directory was simply `C:\cmdstan`. This I renamed manually to `C:\cmdstan-2.30.1`. Could this have been a problem?

I would really really like to get this working.

To fix that issue, make a `make/local` file and add the following two lines:

```nohighlight
CXXFLAGS += -Wno-nonnull
TBB_CXXFLAGS= -U __MSVCRT_VERSION__ -D __MSVCRT_VERSION__ =0x0E00

```

Holy shit, that worked.
