#8842: Make sure msys2 builds non emulating binaries -------------------------------------+------------------------------------- Reporter: schyler | Owner: Type: task | Status: infoneeded Priority: normal | Milestone: 7.12.1 Component: Build System | Version: 7.8.1-rc2 Resolution: | Keywords: msys2 Operating System: Windows | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Changes (by thomie): * status: new => infoneeded * milestone: => 7.12.1 Comment: On Windows, GHC uses a mingw gcc compiler. This command shows that it does define the `_WIN32` macro: {{{ $ /opt/ghc-7.8.3/mingw/bin/gcc -dM -E -x c /dev/null | grep ' _WIN32' #define _WIN32 1 }}} I also compiled a small c program containing an `#ifdef _WIN32` block on Windows using `ghc -c`, and it indeed showed that `_WIN32` is defined. The [wiki:Building/Preparation/Windows build instruction on Windows] for GHC itself are also pretty clear to use the non-emulating version of MSYS2. Anything else I can do to check this? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8842#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
