Hi, I uploaded a version of ghc that does not use epoll_create1. I chose not to include a little tested runtime check and leave that to ghc upstream developers for the next release. The amd64 build that I uploaded successfully build the haskell-transformers library. Unfortunately, the buildds were unable to build ghc on i386, because the previous ghc version did not have the fix. I think I’ll just do a binary upload myself for this architecture. ghc builds failed on sparc and the kfreebsd’s due to sem_* functions missing (and it mentions sem_unlink, sem_open and sem_post. It seems quite random which one is reported, so this seems to be unimportant). I wonder why it works with amd64 now?
Great! Ian suggested on the other thread that the hack will be needed to bootstrap a working GHC which can then be used without hacks thereafter. amd64 probably works because your previous binary upload wasn't misbuilt for whatever reason. I'll try and get you a patch later. If you want to do it in the meantime: * Patch configure to pass -optl-pthread when building ghc-pwd * Add -optl-pthread to SRC_HC_OPTS in d/rules to explicitly link with pthread everywhere Then when this is built and uploaded everywhere you can hopefully revert the patch and upload what is essentially -3 again. Cheers, Iain
