[GNC-dev] GnuCash 4.0 move windows support to only Windows 10?

Tue Apr 28 12:27:14 EDT 2020

Sumit,

That's something I've wanted to find time for as well. I haven't yet examined the MS STL code, but I expect that it's based on msvcrt rather than llvm's libc so you'd need to use clang-cl to build a project with it. You'll also need to compile the boost libraries we use (filesystem, system, regex, date_time, and locale) and because of boost::locale, ICU,
with clang-cl. In theory you can continue to use the MinGW-w64 dependencies, but in practice that might explode because the C++ binaries will link against msvcrt140 while the MinGW-w64 provided binaries link against the MSYS2 msvcrt. If that's the case then you'll need to use vcpkg to generate as many of the dependencies as it supports and build the rest yourself.

Note that boost libraries and GnuCash must be built to the same C++ standard and that GnuCash's CMakeLists.txt specifies C++17. The C++17-using code didn't get finished in time to make it into 4.0 so if necessary you can change it to C++14.

Please keep us posted on your progress.

Regards,
John Ralls

Whether that build would run on Windows 8.1 I don't know, and for the moment not that important. Our official builds can and will continue to use MingW's clang and gcc for the time being.
