** Summary changed: - zsnes 64-bit searches for libao files incorrectly + libao.so contains hardcoded paths
** Description changed: - ZSNES cannot be compiled as a 64-bit binary, and therefore uses 32-bit - libraries on 64-bit systems. A 64-bit package could be made of the - 32-bit binary relatively easy (whether it would violate Debians - packaging standards or not IDK). + libao2 currently hard codes the paths to it's plugins, located in + /usr/lib/ao/plugins-2/. - Among others, it uses libao for sound output. In Hardy+ only, libao is - available in the package ia32-libs (before Hardy, one had to download - the 32-bit libao and install it manually). ia32-libs correctly places - libao packages at the following path: + This can be shown by running this command: + [code]strings /usr/lib/libao.so.2 | grep / [/code] - From http://packages.ubuntu.com/hardy/amd64/ia32-libs/filelist - /usr/lib32/ao/plugins-2/libalsa09.so - /usr/lib32/ao/plugins-2/libarts.so - /usr/lib32/ao/plugins-2/libesd.so - /usr/lib32/ao/plugins-2/libnas.so - /usr/lib32/ao/plugins-2/liboss.so - /usr/lib32/ao/plugins-2/libpulse.so + This becomes a problem when the 32-bit version of libao is used on a + 64-bit system. It'll check /usr/lib/ao/plugins-2/ instead of + /usr/lib32/ao/plugins-2/, which causes a segfault in zsnes (a 32-bit + only binary). - However, zsnes currently seems to only look for the 32-bit libraries in /usr/lib/ao/plugins-2/, leading to a segfault within zsnes when compiled with --enable-libao and run using the OSS driver like so: - ./zsnes -ad oss + This can temporarily be fixed on user's systems by symbolically linking + the 32-bit plugins located in /usr/lib32/ao/plugins-2/ to + /usr/lib/ao/plugins-2/. A better fix would be to use a relative path + such as ./ao/plugins-2/ instead of the absolute path of + /usr/lib/ao/plugins-2/. - A fix that works is to symbolically link the 32-bit libs in /usr/lib32/ao/plugins-2/ to /usr/lib/ao/plugins-2/, making sure not to overwrite the already existing 64-bit libs. Most of this information I believe I've covered in detail on the ubuntu forums thread I created: - http://ubuntuforums.org/showthread.php?t=588744 + This affects ia32-libs in hardy especially, since it now contains + libao2. ** Changed in: libao (Ubuntu) Sourcepackagename: zsnes => libao ** Also affects: ia32-libs (Ubuntu) Importance: Undecided Status: New -- libao.so contains hardcoded paths https://bugs.launchpad.net/bugs/227475 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
