#14526: GHC fails to configure on MacOS if Cuda is installed -------------------------------------+------------------------------------- Reporter: nehal | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Build System | Version: 8.0.2 Keywords: Cuda | Operating System: MacOS X Architecture: x86_64 | Type of failure: Building GHC (amd64) | failed Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Hello, I had the following issue trying to build ghc (indirectly via stack) {{{ [error] Running /usr/bin/make install in directory /Users/nehal/.stack/programs/x86_64-osx/ghc-8.0.2.temp/ghc-8.0.2/ exited with ExitFailure 2 mk/config.mk:521: *** missing separator. Stop. @(Stack/Setup.hs:991:21) 2017-10-16 07:16:01.831719: [error] Error: Error encountered while installing GHC with make install run in /Users/nehal/.stack/programs/x86_64-osx/ghc-8.0.2.temp/ghc-8.0.2/ }}} Here is the line from `mk/config.mk:521`: {{{ 519 WhatGccIsCalled = /usr/bin/gcc 520 GccVersion = 9.0.0 521 8.0 522 ifeq "$(phase)" "0" ... }}} output from gcc: {{{ nehal$ gcc -v Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1 Apple LLVM version 9.0.0 (clang-900.0.37) Target: x86_64-apple-darwin16.7.0 Thread model: posix InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin Found CUDA installation: /usr/local/cuda, version 8.0 }}} It looks like the version detection is getting confused by the cuda installation (and so is thinking the version is something like `"9.0.0\n8.0"`) This could be something for further upstream (e.g. autotools mainainters), but I'm just rebooting my "try to grok Haskell" efforts, so I am going to take the lazy approach and report it here.... Thanks for ghc!
