Hi,

only the frd.c-file has to be replaced.

The GitHub file fits the present development version, not version 2.20 (although  
the difference in this case is quite small).

I will upload file frd.new.c to [http://www.dhondt.de](http://www.dhondt.de), so you get it by  
downloading [http://www.dhondt.de/frd.new.c](http://www.dhondt.de/frd.new.c)

Best,

Guido

fixed for macOS 10.13!

Thanks.

" 2022-10-29 - Changing the default environment from MINGW64 to UCRT64

About 1.5 years ago we started adding a new variant of the MINGW64 environment called [UCRT64](https://www.msys2.org/docs/environments/), which uses the Universal CRT instead of the old msvcrt.dll. Now that all our packages are available in this new environment and a very large percentage of our users (~97%) are on a system that includes UCRT, we recommend it as the default environment instead of MINGW64.

The MINGW32/64 environments will continue to exist and there are no plans to remove them, but we will focus our attention more on UCRT64 and the other UCRT-using environments such as CLANG64 and CLANGARM64."

Results for ucrt version (for mingw OK):

The only difference in the source code is: `&& !defined(_UCRT)`

```auto
#if defined(_WIN32) && !defined(_UCRT)
_set_output_format(_TWO_DIGIT_EXPONENT);
#endif

```

Great, apparently the problem is fixed. With the mingw64 version of Rafal’s build, I obtained complete results for all of the few tries that I did.

Did you keep that code outside the function body? I find that Mingw-w64 won’t compile when it’s there but only if it’s moved inside `CalculiXstep()` and `main()`.

No doubt it works anywhere on UCRT64 because it’s now `#if`’d out.

I can confirm that this issue is fixed in CalculiX 2.21.
