#10973: Building git HEAD with a singe make job fails due to dependency problem -------------------------------------+------------------------------------- Reporter: erikd | Owner: Type: bug | Status: new Priority: normal | Milestone: 8.0.1 Component: Build System | Version: 7.11 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Building GHC | Unknown/Multiple failed | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Description changed by erikd: Old description:

If I clone git HEAD and do:

{{{ perl boot && ./configure && make }}}

The build fails with:

{{{ /usr/bin/ld: cannot find -lHSghc-boot-0.0.0.0 collect2: error: ld returned 1 exit status }}}

and it keeps failing if I run `make` without any `-j` option.

Building with `make -j<N>` where `N` is 2 or more is fine.

Looks like some sort of dependency problem.

Doing a `make clean` followed by `make -j<N>` with N >= 2 is fine. Akso building from scratch with: {{{ perl boot && ./configure && make -j<N> }}} with N of 2 or more is fine. Looks like some sort of dependency problem. -- -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/10973#comment:1> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

One such hack filtered on 'ghc%', with the intention of filtering the ghc package only. After renaming bin-package-db to ghc-boot (d2f9972a35ce05ceb8a78893e433ef1df06f73ef, Phab:D1313, #10796), ghc-boot also got caught in the hack, which broke the build when running without parallelism. This patch replaces the before mentioned hack by a different one, such that filtering on 'ghc%' is no longer necessary. See Note [inconsistent distdirs].
