[[!meta title="ZSNES on AMD64 Ubuntu"]] [[!meta date="2010-10-06"]] [[!meta author="rohieb"]] [[!meta license="CC-BY-SA 3.0"]] [[!flattrthing id=80701]] **[ Update, 2013-10:** This post post is not up to date anymore. On newer Debians (since 7.0/wheezy) and Ubuntus (at least since 12.04, Precise Pangolin), you should be able to install zsnes out of the box: `sudo apt-get install zsnes:i386`. For details see the MultiArch documentation for [Debian][MultiArchDebian] and [Ubuntu][MultiArchUbuntu]. **]** [MultiArchDebian]: https://wiki.debian.org/Multiarch/ [MultiArchUbuntu]: https://help.ubuntu.com/community/MultiArch Before I bought my current hardware, I was working on a 32-bit-based system, and I really appreciated ZSNES as an SNES emulator. But unfortunately, my new hardware was an AMD64 system, and there is currently no ZSNES package for 64-bit Ubuntu or Debian :( So I decided to google a bit about the issue, but it took me until now (a year later) to get ZSNES finally working on my machine. The problem is, if you build ZSNES on a 64-bit machine, all the application does is segfault at start, and if you [try to compile for 32-bit systems][0], you get errors about missing 32-bit libs (in particular, configure does not find a suitable `libsdl`). Instead, if you just take the binary which was compiled on a 32-bit system, and install the `ia32-libs` package, everything seems to work—at least I was able to play a few levels of Super Mario World succesfully :-) [0]: http://board.zsnes.com/phpBB3/viewtopic.php?p=118067&sid=dd9a2a54d9178eb5009c33586aea703c#p118067 So here was my idea: take the 32-bit package from the Ubuntu repository, and just change the Architecture control field, and by this fool dpkg :P And as it turned out, this idea worked great. You can get the Debian package here if you want, it *should* work for Ubuntu Karmic and Lucid, as well as for Debian testing (**but** I only tested it on Lucid, so there is no warranty here—but I’m happy to hear if it works :-)): * [zsnes_1.510-2.2ubuntu3~ppa1_amd64.deb][2] * SHA1: `716bbd37267b477ef02961a7727212619309b83f` * MD5: `452ea5230ad17df1dee649ab4cc6c8c0` [2]: http://rohieb.name/stuff/zsnes_1.510-2.2ubuntu3~ppa1_amd64.deb ## How to Reproduce It For the curious people reading here, here is what I actually did: 1. `wget http://archive.ubuntu.com/ubuntu/pool/universe/z/zsnes/zsnes_1.510-2.2ubuntu3_i386.deb` 2. `ar x zsnes_1.510-2.2ubuntu3_i386.deb` 3. `tar xzf data.tar.gz` 4. Edit `usr/share/applications/zsnes.desktop` and added `-ad sdl` to the `Exec:` field, otherwise it would just segfault on the first run: Exec=zsnes -ad sdl 5. Edit `usr/share/doc/zsnes/changelog.Debian.gz` and added a new changelog entry for the version (just copy one of the previous entries and adapt it) 6. `tar xzf control.tar.gz` 7. Edit the `control` file, changed the `Version:` and `Architecture:` field to `amd64`, added the `ia32-libs` dependency, and set myself as maintainer: Package: zsnes Version: 1.510-2.2ubuntu3~ppa1 Architecture: amd64 Maintainer: Roland Hieber Installed-Size: 4160 Depends: ia32-libs, libao2 (>= 0.8.8), libc6 (>= 2.4), libgcc1 (>= 1:4.1.1), libgl1-mesa-glx | libgl1, libpng12-0 (>= 1.2.13-4), libsdl1.2debian (>= 1.2.10-1), libstdc++6 (>= 4.1.1), zlib1g (>= 1:1.2.2.3) [...] 8. Change the `md5sums` file for the right values for `usr/share/applications/zsnes.desktop` and `usr/share/doc/zsnes/changelog.Debian.gz` (I used the `md5sum` command and copy-pasted it) 9. `tar czf control.tar.gz control md5sums postrm postinst` 0. `tar czf data.tar.gz usr/` 1. `ar r zsnes_1.510-2.2ubuntu3~ppa1_amd64.deb debian-binary control.tar.gz data.tar.gz` I’m afraid that I can’t put the package into [my PPA][3], Launchpad only accepts source packages for uploads, and builds the binary packages itself, both for i386 and AMD64. This approach can not be used here, since we needed the i386 binary for AMD64.
