Msys on Windows misses header file "locale"

[openmodelica@…]

I tried to compile code of a self-created modelica library with 1.17.0-beta3-64bit

Error message:
C:\OpenModelica1.17.0-dev.beta3-64bit\tools\msys\mingw64\include\c++\10.2.0\iomanip:44:10: fatal error: 'locale' file not found
#include <locale>

Investigation:

• Open msys shell, in my case
  • C:\OpenModelica1.17.0-dev.beta3-64bit\tools\msys\msys2_shell.cmd
• see who owns the "locale" header file:
  • pacman -Qo /mingw64/include/c++/10.2.0/locale
    • the result is "/mingw64/include/c++/10.2.0/locale is owned by mingw-w64-x86_64-gcc 10.2.0-5"
• check if it is there
  • ls /mingw64/include/c++/10.2.0/locale
    • ls: cannot access '/mingw64/include/c++/10.2.0/locale': No such file or directory

So i guess the installer does not ship that file. Let's see if there are more files missing:

• pacman -Ql mingw-w64-x86_64-gcc | cut -d" " -f2 | grep -ve"/$" | xargs -n1 ls
  • except for man-pages which are not essential, locale is the only file missing

Fortogt to mention: the workaround is, installing the package again:

pacman -S mingw-w64-x86_64-gcc

We do have it in our OMDev git repository so the installer filters it out it seems:

I'll fix this asap.

Fixed with 181f6a1/OpenModelicaSetup (master) and a81487a/OpenModelicaSetup (maintenance/v1.17).
