#8260: Parallel build behaves erratic under Windows ----------------------------------+---------------------------------------- Reporter: schyler | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Build System | Version: 7.7 Keywords: | Operating System: Windows Architecture: | Type of failure: Building GHC failed Unknown/Multiple | Test Case: Difficulty: Unknown | Blocking: Blocked By: | Related Tickets: | ----------------------------------+---------------------------------------- Under Windows, `make -j4` will freeze randomly all through the build system (every ~ 1-2 minutes). The only way to get it to resume it is to kill the make process and restart it. It sometimes even freezes on things like `rm` or `happy`. This makes building GHC take an unbearably long time. Tested on latest MinGW. {{{ GNU Make 3.81 Copyright (C) 2006 Free Software Foundation, Inc. This is free software; see the source for copying conditions.
