[msink]

Trying to statically link SDL in Tetris sample:

get this error:

Seems like it's same as rust-lang/rust#47048 - msys2 now uses mingw-w64-x86_64-crt-git-6.0.0, but Kotlin uses bundled with clang-5.0 mingw-w64-x86_64-crt-git-5.0.0.

Well, on llvm6 branch crt issue fixed, but now instead of single SDL2.dll it requires 3 libs: libgcc_s_seh-1.dll libstdc++-6.dll libwinpthread-1.dll

Well, it's still marked as WIP :)

Found it - -Wl,-Bstatic -lstdc++
So final path to fully static tetris for mingw on llvm6 branch:

Fixed in master.
