freenode server seems in trouble for this while, and I'd like to take this chance to report my progress to the mailing lists. I'm thankful to folks at #ghc and #smartos who helped me so much in this journey, especially bgamari, without his hints and bleeding edge patches this won't be possible at all. And https://www.mail-archive.com/smartos-discuss@lists.smartos.org/msg05016.html provided the information to get me started at all. So far what's done: :: installed 7.6.3 -> booted 7.10.3 -> booted 8.2.2 -> booted 8.4.4 -> booted 8.6.5 -> booted 8.8.2 Notable issues as I remembered: (I don't remember the details clearly, anyway am to redo it all over again to have everything logged for reprod) * `gmake -i` is used to build 8.2.2 to workaround the stage1 ghc crash after target file generated * 8.6.5's ghci won't start | [root@hswander /build/ghc8]# /opt/local/ghc8.6.5/bin/ghci||| ||| GHCi, version 8.6.5: http://www.haskell.org/ghc/ :? for help||| ||| ghc: loadArchive: Not an archive: `/usr/lib/iconv'||| ||| ghc: panic! (the 'impossible' happened)||| ||| (GHC version 8.6.5 for x86_64-unknown-solaris2):||| ||| loadArchive "/usr/lib/iconv": failed||| ||| Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug||| * worth to mention that I needed to put "SplitSections=YES" into mk/build.mk even for 8.8.2 or it'll fail, might be unexpected. And dtrace compiler on latest SmartOS don't support C++ style line comment, so I applied this patch to 8.8.2 https://gitlab.haskell.org/snippets/1549 Meanwhile I'm starting a fresh smartos vm to repeat (and log) all steps to make sure others and future me can follow such a reproducible procedure to build later versions.
