#16153: ghc 8.6.3 fails to build on macOS Sierra, High Sierra and Mojave (10.12 to 10.14) -------------------------------------+------------------------------------- Reporter: fxcoudert | Owner: (none) Type: bug | Status: infoneeded Priority: normal | Milestone: Component: Compiler | Version: 8.6.3 Resolution: | Keywords: Operating System: MacOS X | Architecture: x86_64 Type of failure: GHC doesn't work | (amd64) at all | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari):
Does the testsuite not support parallel build? The testsuite does support parallel execution. However, to enable parallel execution you must use the `THREADS` variable.
For instance, {{{ make test THREADS=9 }}} For details see wiki:Building/RunningTests/Running.
It used to work without issue in previous versions, such 8.4.4.
I'll admit I'm a bit skeptical; GHC's testsuite driver has never supported parallel execution using `make -j` as far as I know. Perhaps it didn't break as violently, but it certainly never worked. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16153#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
