Alexey,
I ‘ve taken a look at the wiki page and in my opinion the role of msys2 is not
clear . It is claim : "Technically, the major difference between MSYS2 and
Cygwin is that MSYS2 makes every effort to interoperate with native Windows
software as that is often a requirement for running and (by extension) building
such software. »
Ok but ,if I use the default compiler (/usr/bin/gcc) the final executable is
linked to msys2.dll , something like cygwin and if I’ve understood in order to
build an executable fully compliant with MS Windows I’ve to use
/mingw64/bin/gcc.
What is philosophy (the reasons) behind that ?
I’m just trying to clearly understand the msys2 architecture in oder to use it
in the right way.
Regards
Michel
