Hello! I have been busy almost the whole evening yesterday to bootstrap ghc on Debian sh4 yesterday. I successfully cross-compiled ghc for sh4 and installed a mini ghc distribution into my sh4 sbuild chroot. I still have some minor issues with the ghc package database so that I cannot build the Debian ghc package for sh4 yet, but otherwise, ghc on sh4 is fully working.
Thus, if anyone wants to get their hands at bootstrapping ghc for sparc64 - which I would highly appreciate - here's what you need to do to get a stage2 (a native) compiler for sparc64: 1. Install ghc on your amd64 build machine and its build dependencies: $ apt-get install ghc && apt-get build-dep ghc 2. Install the sparc64 gcc cross toolchain: $ apt-get install gcc-sparc64-linux-gnu 3. Download the right version of ghc from Debian: $ wget http://snapshot.debian.org/archive/debian/20151203T214229Z/pool/main/g/ghc/ghc_7.10.3.orig.tar.xz 4. Unpack the source tarball: $ tar xf ghc_7.10.3.orig.tar.xz 5. Apply this patch: https://phabricator.haskell.org/D1430 6. Run configure with sparc64-linux-gnu as TARGET: $ ./configure --enable-unregisterised --target=sparc64-linux-gnu --with-curses-libraries=/usr/lib/sparc64-linux-gnu --with-curses-includes=/usr/include --with-gmp-libraries=/usr/lib/sparc64-linux-gnu --with-gmp-includes=/usr/sparc64-linux-gnu/include 7. Edit ghc's build configuration to build ghc's BuildFlavour "quick-cross" only. $ cp mk/build.mk.sample mk/build.mk and uncomment "BuildFlavour = quick-cross" In the same file, check that in the section for "quick-cross" further below, you remove "-fllvm" everywhere. Here you can also control with ("stage=1" or "stage=2") whether you want to build just stage1 or right away stage2 the latter requiring to move the code over onto a native sparc64 to continue the build at some point. 8. Run "make". Let me know about your results. This guide is still incomplete but if everything goes well, you should end up with a minimal stage1 and/or stage2 compiler respectively. Adrian -- .''`.
