I noticed a few years ago there was talk about DOSBoxes that do save states, but the only one I can find is Daum, which doesn't work in 64-bit Linux. Is there something 2015 that can do this?
Daum runs fine in 64-bit Linux: if you're running the prebuilt binaries from YKHWong's web site, just make sure you've got the 32-bit versions of the needed libraries installed. How you do this will vary from distro to distro -- in Arch, you'd enable the multilib repos, then install the 'lib32' packages for the libraries you need. Alternatively, you can always build from source and generate a native 64-bit binary -- there's a source archive downloadable alongside the binary distribution. A third option, which may be the easiest to configure (but not likely the best in terms of performance) is to run the Windows binary under Wine.
Unfortunately, w/my distro (Ubuntu) it looks like I'd have to uninstall my 64-bit libraries in favour of the 32-bit ones. I know, it's crazy. I usually don't like to bother trying to build these things from source. I wind up wasting a lot of time trying to setup the build environment, and in the end, give up. Since Daum is so thinly supported, I'm sure that's what would happen.
It appears that you *can* get the 32bit stuff in parallel... http://askubuntu.com/questions/454253/how-to- … n-ubuntu-64-bit
Appears, yes, but I don't think it's that simple. You still need the 32-bit libraries, which are usually supplied by the distro. In my case, when I try running it I get:
error while loading shared libraries: libtbb.so.2: wrong ELF class: ELFCLASS64
If I try to install the i386 libtbb.so.2, I'm told that it'll have to uninstall the 64-bit one, plus all the apps that rely on it.
Did you google it? I know it's possible but I can't really spend more time on another OS that I'm not using 😉
I did. The solution to everything after that library name in that error is to install the 32-bit version. The solutions for that specific library are elusive. I don't think there's a clean solution.
The "proper" way to do this is to have all your native (64-bit, if your OS is 64-bit) libraries in /usr/lib, and then the 32-bit libraries go into /usr/lib32. If you are trying to install a package from a 32-bit version of your distro, it will most likely try to install into /usr/lib, as this is the native path for that 32-bit distro. This will end up overwriting the 64-bit version in there already, which is not what you want.
What you need is a 64-bit aware, 32-bit package. This will install the 32-bit libraries into /usr/lib32 instead, allowing them to coexist on a 64-bit platform without trying to overwrite the 64-bit libraries.
You can either look in your distro's repositories for these 64-bit aware packages (for example on Arch, the 64-bit aware, 32-bit version of the "sdl" package is called "lib32-sdl") or worst case, extract the libraries from the 32-bit package and manually put them into /usr/local/lib32. Then as long as you have included /usr/local/lib32 in your library search path (/etc/ld.so.conf) it should work.
