[GHC] #8842: Make sure msys2 builds non emulating binaries
#8842: Make sure msys2 builds non emulating binaries ------------------------------------+--------------------------------- Reporter: schyler | Owner: Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.1-rc2 Keywords: | Operating System: Windows Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+--------------------------------- I came across this in my own project. MSys2 doesn't enter #ifdef blocks which test for _WIN32. Instead, it pretends to be Linux and has a set of headers which emulate things like mmap. These emulation functions are really really slow -- in my personal tests about 10x slower than calling the WINAPI -- so this ticket is just a reminder (it may already be done) for someone to check that MSys2 builds things non-emulated in GHC. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8842 GHC http://www.haskell.org/ghc/ The Glasgow Haskell 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
