Add clang instructions for building Win64 julia #17223
Conversation
| 2. Set clang as your default compiler: | ||
| ``` | ||
| cat > Make.user <<EOF | ||
| override CC_ARG=--sysroot=$(HOME)/julia/usr/x86_64-w64-mingw32/sys-root/mingw -target x86_64-w64-mingw32 |

should also separate instructions for 32 vs 64 bit build

Bullet 1 assumes $(HOME)/julia, if people adjust this, that's their own business.

only implicitly, if you assume people clone from home. should be more generalizable via pwd

I'd rather have this out of line as a separate bullet since it's not widely tested. |

It's the only configuration that actually works at the moment. Following the instruction as is will get you a gcc that miscompiles LLVM. |

I also consider msys2 effectively unsupported, but opensuse has upgraded to gcc 6 which fixed the issue with ipa-ra. |

closed because we're not actively supporting msys2 right now. there is a clang-cross package in cygwin these days but libgmp's build system is still broken with it |
